Purpose of the manual

Instrument utility

NOTE

INTRODUCTION

This manual has been written to provide the information necessary for proper installation, operation, and maintenance of the CANNON Rotary Viscometer (CMRV-4500).

The CANNON viscosity and yield stress of engine oils and drive line lubricants within the temperature range of -10 4684, D 3829, D6821 and D 6896. ASTM test method D 4684 is required by the Society of Automotive Engineers (SAE) Engine Oil Viscosity Classification SAE J300.

The CMRV-4500 capabilities have been tailored to the requirements of the current ASTM methods cited above. For this reason, the instrument may not be suitable for some general-purpose viscometry applications. Consult with CANNON® Customer Service before testing with materials and/or methodology at significant variance with ASTM D 4684, ASTM D 3829 or ASTM D 6821.

 Networking capability for multiple instruments

The VISCPRO

software can control/monitor up to four CMRV instruments with one computer via RS-485 serial connections. See APPENDIX D for more information.

Instrument overview

The CANNON® Mini-Rotary Viscometer is designed for precision control of temperature over time, enabling accurate yield stress and viscosity measurement of oil samples in conformance with ASTM D 3829, ASTM D 4684, ASTM D 6821 and ASTM D 6896 test methods.

Test procedure

Oil samples placed in the CMRV-4500 viscometric cells are heated and cooled at a predetermined rate according to a user-specified cooling profile. The cooling profile parameters are downloaded to the CMRV4500 onboard memory via a serial interface with the host computer. The CMRV-4500 then uses this profile to control the rate of temperature change, independent of the host computer.

All three methods specify that the samples be initially heated to ensure that all components of the sample are released into solution. The samples are then slowly cooled to the test temperature using the user-selected temperature profile and maintained at test temperature for a specified soak period. Following the soak period, apparent viscosity (and yield stress if applicable) for each sample is determined by applying a constant torque to, and measuring the rotational speed of, a cylindrical rotor which has been immersed in the sample.

The time required for completion of the ASTM D 3829 test cycle is approximately 19 hours. The time required for completion of the ASTM D 4684 (TP-1, two-day) test is 45½ to 53½ hours. The time required for completion of the ASTM D 6821 test cycle is approximately 18 hours. The time required for completion of the ASTM D 6986 test cycle is approximately 43½ to 53½ hours.

CHAPTER

CMRV-4500 APPARATUS

CMRV-4500 unit/accessories

The CMRV-4500 unit contains an aluminum block with a heater for warming the block. Nine viscometric cells are closely fitted into nine holes in the block (see photo). There are also two thermometer wells in the block.

Lower rotor bearing

Each viscometric cell consists of an aluminum block aperture with a rotor resting in a stainless steel cup at the base. The rotor is attached to a rotor shaft with a pivot point at the bottom. The pivot point fits a mating conical depression at the bottom of the stainless steel cup; this mechanism serves as the lower bearing. The standard rotor composition is hardened stainless steel. The drive line rotor composition is Delrin (NOTE: The drive line rotors/pins/ weights must be purchased separately from CANNON®.)

DESCRIPTION

CMRV-4 unit with rotors inserted and thread wound on pulley-wheel

Rotor for oil testing (top) and

drive line lubricant testing

Upper rotor bearing

CANNON

The upper bearing consists of a brass insert at the top of the rotor shaft with a 1.2 mm hole on the shaft axis. A cylindrical rotor pin is inserted through the upper bearing plate about one or two millimeters into the hole on the shaft axis.

Rotor crossbar

Rotor locking pins

Pulley-wheel assembly

The rotor crossbar is used to hold the loop at the end of the thread. It also serves as an indicator for (optional) manual timing of rotor rotation.

The rotor locking pins

String on rotor and pulley-wheel assembly

are used to prevent unwanted rotor rotation. When the locking pin is lowered over the rotor crossbar (see photo), rotation is prevented. When the pins are in the raised (detent) position, the rotors are free to rotate.

The pulley-wheel assembly consists of a V-channel timing wheel with a digital-optical sensor permitting precise measurement of the wheel rotation. The pulley-wheel base is designed to be fitted to the CMR V-4500 slide track adjacent to the viscometric cells. The probe

Slide track with pulley-wheel assembly

cable is connected to the jack on the front of the CMRV-4500 housing.

Winding thread

Slide track

CANNON

The thread used for CMRV-4500 testing is a single, nonelastic strand of 70 cm (28") winding thread of silk, cotton, or similar material (Coats North America or comparable brand, 0.1 mm radius) with a loop on one end. One end is wound around the CMRV-4500 rotor. The other end of the thread is tied to a small rigid plastic ring from which the test weight may be suspended.

The pulley-wheel assembly is designed to interlock with the pulleywheel slide track and move laterally so it can be aligned with the scored marks on the track opposite each of the nine rotor shafts.

Hook-weights

Temperature probe

Thermometers

Hook-weights are hung on the plastic ring at the free end of the thread to apply the required force to the rotor during yield stress and viscosity measurements. Nine disk weights, one hook-cage, and one larger hook-weight are provided. Weights vary depending on the ASTM Method used for testing.

CMRV-4500 block temperature is detected by a 3k-ohm temperature probe, which must be seated securely in the thermistor aperture at the rear of the CMRV housing and plugged into the electronic chassis.

Hook-weights

The CMRV-4500 unit is shipped from CAN-

with two thermometers to be used to check the temperature of the

NON

block.

 The long thermometer used for the probe and cell calibrations is a

PRINCO mercury-thallium calibrated thermometer with a range of

-46°C to +30°C in .2°C increments and an accuracy of ± 0.01°C below 20°C.

NOTE

If a thermometer is removed from the CMRV-4500 when the unit is cooling, plug the thermometer aperture in the Plexiglas® cover to prevent ice formation around the rotors.

 The shorter, high-temperature uncalibrated thermometer has a range

of 0°C to 105°C in 1°C increments with an accuracy of ± 1°C.

Air/Water Heat Exchanger

CMRV-4500 cooling is accomplished with internal thermoelectric cells and an external Air/W ater Heat Exchanger circulating a mixture of water and antifreeze to remove heat from the thermoelectric modules.

The Air/Water Heat Exchanger contains the electronics necessary to monitor the coolant flow rate and regulate the action of the circulating pump during the running of ASTM-specified temperature profiles. The Heat Exchanger also supplies DC power for the operation of the CMRV thermoelectric modules.

SETUP

The instructions in this chapter are for setting up a single CMRV-4500 with the Air/Water Heat Exchanger. For additional information on multiunit configurations, see APPENDIX D.

Do not apply power to the CMRV-4500 or Heat Exchanger until all connections are secure.

Some CMRV components, including the Air/Water Heat Exchanger, are quite heavy. To avoid injury, obtain necessary assistance when lifting and moving these components.

Place the CMRV-4500 on a stable laboratory bench or table top within 10 mm of the front edge. This will allow the weight suspended from the pulley-wheel assembly to clear the edge of the table during viscosity and yield stress tests. Allow 30.5 cm (12") of clearance to the back and sides of the unit.

CAUTION

Thermometer placement

NOTE

Place the Air/Water Heat Exchanger below the table top on which the CMRV-4500 is placed. The unit may be located within the parameters permitted by the length of the hoses and cables shipped with the unit.

Do not obstruct the front or rear cooling vents on the Air/Water Heat Exchanger.

When in use, the large thermometer (-46°C to +30°C) is placed in the thermometer well on the left side of the CMR V-4500 unit (seen from the front).

When in use, the small thermometer (0°C to 105°C) is placed in the thermometer well on the right side of the CMR V-4500 unit (as seen from the front).

If the mercury column in a thermometer has separated during shipment, read the instructions included in APPENDIX C. These instructions offer several methods for joining separated mercury columns.

PREPARING FOR CMRV

TESTING/CALIBRATION

The procedures in this chapter should be followed when preparing for CMRV-4500 testing or calibration.

In the event that the protocols of your ASTM test method differ from any of the procedures outlined in this manual, the ASTM method should take precedence.

T o prepare for operation of the CMRV-4500 unit, turn on the POWER switch on the upper rear panel of the Air/Water Heat Exchanger.

The ice point of the CMRV-4500 thermometers should be checked periodically at 76 mm immersion, which corresponds to the depth of immersion in the CMRV-4500 aluminum block.

Cleaning cycle

CAUTION

Cleaning procedure

Small deviations in the ice point (less than 0.4°C) should be noted and added to (or subtracted from) calibration readings at all other temperatures (See section on temperature calibration). If corrections larger than

0.4°C are needed, there may be a problem with the thermometer. Examine the thermometer for a bubble of gas in the lower reservoir, a bubble of mercury in the upper reservoir, or a break in the mercury column. For information on joining separated mercury columns see APPENDIX C.

Clean the rotors and all nine viscometric cells as described in the following procedure.

When handling the rotors, be careful not to damage the rotor tips. Damage to the tips will cause erroneous test results and may damage the cells.

When operating the CMRV, make sure that the rotor and cell numbers coincide (use the #1 rotor in cell #1, the #2 rotor in cell #2, and so on). Failure to do so may diminish test accuracy and void the cell calibration constants.

1. Remove the Plexiglas® cover from the CMRV-4500 and place it away

from the cleaning solvents.

3. Insert the pin through the plate and into the center bearing hole at the

top of the rotor shafts.

The pins, when inserted through the upper bearing plate, should extend approximately 3 mm (1/8 inch) below the plate.

4. Make sure that the rotor locking pins are in the raised (detent)

position. Rotate each of the rotors to ensure that it spins freely and without signs of binding at either bearing.

5. Remove the rotors from the viscometric cells.

6. If necessary, install the pulley-wheel assembly on the slide track. See

Chapter 4 for details.

7. Make sure that the free end of the sensor wire from the pulley-wheel

assembly is plugged into the receptacle marked WHEEL on the CMRV-4500 front panel.

You are now ready to perform the CMRV-4500 calibration procedure or run a test sample using the applicable test methods or a custom profile. See the appropriate chapter for further instructions.

CHAPTER

CALIBRATING THE CMRV

TEMPERATURE PROBE

The CMRV temperature probe must be calibrated before performing the initial cell calibration or running temperature profiles. A complete calibration session involves setting temperature offsets in the VISCPRO software for key temperature checkpoints beginning at 80°C, then 50°C, then other temperatures at 5-degree increments from 0 to -40°C. The calibration process ensures that temperature probe readings are correctly interpreted by the CMRV hardware and software. This ensures accurate temperature control throughout the temperature profile.

There is a 10-minute equilibration time at each calibration temperature. The entire calibration procedure requires at least 3 hours and requires operator input at each temperature plateau. Thereafter, the probe should be calibrated at the user's discretion, particularly when viscosity data is suspect, the instrument exhibits poor repeatability , or the probe temperature on the display does not correspond with the calibrated thermometer reading.

Probe calibration procedure

Checking temperature probe

NOTE

Both the CMRV probe calibration and cell calibration procedures should be completed shortly after initial installation of the CMRV software. Probe calibration must precede cell calibration to ensure accurate temperature control during the cell calibration process. Periodic probe calibration will enhance the accuracy of test results.

1. After preparing the CMR V instrument (see Chapter 6), place 10 ml ± 0.1

ml of any clean generic oil sample into each of the viscometric cells being calibrated. Carefully place the rotors into their corresponding viscometric cells and secure each rotor in position with the rotor pin.

2. Make sure that the thermistor probe sheath is securely seated in the

cylindrical opening on the rear of the CMRV housing.

3. Using the VISCPRO

NOTE

In each calibration session, the initial probe calibration must be performed at 80°C (see procedure below) before calibrating at other temperatures. When prompted by the VISCPRO software: "Do you want to zero the offset at 80°C before calibrating?", click YES the first time in the session that you attempt to calibrate at 80°C. Thereafter, click NO unless you would like to start the calibration over from the default offset value.

The CMRV unit will begin heating or cooling to the desired temperature. When it reaches temperature, a 10-minute timer will start. This delay allows the CMRV temperature to stabilize at the calibration temperature. Note that more time may be required for stabilization at 80°C, 50°C and 0°C. After the timed delay, the Thermometer Temperature °C field will become active, enabling data entry.

5. After the instrument reaches the probe calibration temperature and

completes the temperature stabilization period, type the actual temperature from the reference thermometer in the Thermometer Temperature °C field. Then click the Accept button to store the temperature calibration offset to the current instrument configuration.

6. Click the Calibrate button again to reset the timer and check the

calibration for that temperature. If the reference temperature varies from the displayed temperature, repeat steps 5 & 6.

NOTE

Make certain to use the "-" key when entering a temperature below 0°.

7. Repeat steps 4 through 6 for each desired calibration temperature.

Then click to exit the Temperature Probe Calibration window.

NOTES

Make certain to SAVE the instrument following a successful calibration (File/Save Instrument). You should also print an archive copy of calibration data (click Configure/MRV/Print Instrument Settings). A partial calibration session may enable you to run some profiles as long as the coldest calibration offset is 5° lower than the lowest profile temperature.

Manual restoration of voltage and offset data

If the VISCPRO database is corrupted, or if temperature calibration data is lost for any other reason, voltage and temperature offset values may be manually restored without recalibrating the instrument. Existing data can be viewed by clicking Service/MRV/Temperature Probe Calibration. When the user is logged into VISCPRO as a Manager, the Temperature Probe Calibration window displays additional security-protected controls for manual adjustment/ restoration of voltage and offset values obtained during the probe calibration.

T o manually adjust temperature offsets or voltage reference values, log into the VISCPRO software as a Manager. Then open the probe calibration window (Service/MRV/Temperature Probe Calibration). The Reference Supply Voltages and offset fields will now be editable. Use your printed copy of the most current instrument settings to determine appropriate values and input the values in the indicated fields. Click OK when the values have been entered correctly. Then click the Accept Manually Entered Offsets and V olt ages button.

CALIBRATING THE

CMRV CELLS

T o ensure the accuracy of sample data, the CMRV -4500 cell calibration procedure must be completed after initial installation of the software. First complete the temperature probe calibration (see previous chapter) and instrument preparation (Chapter 6). Then follow the procedure in this chapter to calibrate the CMRV cells.

After the initial calibration, CANNON calibrated every 4-8 weeks at the discretion of the user. Note that some ASTM methods may require multiple calibrations prior to sample testing. These ASTM profiles will not appear in the drop-down list until all calibration(s) required by the method is/are performed.

Each of the nine viscometric cells must be calibrated to determine the relationship between viscosity , angular velocity of the rotor, and the applied mass.

The general calibration constant is determined from the following equation:

where C' = general calibration constant, millipascals (mPa)

r = number of full revolutions η = known viscosity of calibration oil at the calibration

temperature in centipoise (cP) (1 centipoise = 1 millipascal second (mPa·s (cP))

M = applied mass, grams (g) m = mechanical friction of bearings, grams (g) t' = time for r revolutions in seconds (s)

When this test is run according to the applicable ASTM procedures, m is negligible relative to M, r = 3, and M = 150. Thus, for convenience, the calibration equation can be simplified as follows:

CANNON

viscosity standard N105B is recommended for calibration at

-20°C and -25°C. This calibration is required for running ASTM profiles included with the software. At -20°C, N105B has a nominal viscosity of 30,000 cP (mPa·s). At -25°C, N105B has a nominal viscosity of 56,600 cP (mPa·s).

It is also possible to calibrate the CMRV cells at -25°C using viscosity standard N400B with a nominal viscosity of 60,000 cP (mPa·s).

CANNON

Instrument Company can furnish viscosity standards for a variety of temperatures and viscosities. The CMRV-4500 can be calibrated over the viscosity range of 1 to 99,999 cP (mPa·s).

After you have prepared the CMRV-4500 for the calibration run (see Chapter 6) follow the procedure below to calibrate the CMRV.

1. Place 10 ml of the calibration

standard into each of the nine cells (see photo).

2. Carefully place the rotors in

their corresponding viscometric cells, making sure that the rotor tip at the bottom of the shaft slides into the recess at

Winding rotors

CANNON

3. Secure each rotor in position with a rotor pin, and make sure that the

rotor locking pin is in the raised position.

4. To wind the rotors in preparation for the cell calibration, slide the

pulley-wheel assembly along the track until the pulley is aligned with the rotor to be wound. Use the engraved lines on the slide bar as a guide to determine the proper position of the left side of the pulleywheel block.

5. Place the loop of a thread over the left end of the crossbar at the top

of the rotor shaft.

6. Pass the free end of the thread (the end with the plastic ring) over the

pulley-wheel and allow it to hang freely in front of the viscometer. While holding the rotor motionless, hook a light weight, such as a large paper clip, on the plastic ring to apply slight tension to the thread.

7. Guiding the thread with your finger, turn the rotor clockwise to wind

the thread above the crossbar until the knot in the loop has been

Then pass the thread below the crossbar and continue turning the rotor clockwise (as viewed from above) to wind 20 closely spaced turns of thread around the shaft below the crossbar without overlapping the turns. About 200 mm (8 inches) of thread will remain. Place this remaining length of thread over the upper bearing support plate so it hangs to the rear of the viscometer and secure the rotor in place by lowering the rotor locking pin over the rotor crossbar (see figure and photo).

NOTES

Cell calibration test procedure

Cell calibration

To reduce the chance of separating the mercury column during the heating phase of the temperature profile, you may wish to initially remove the calibrated thermometer from the CMRV unit. Store the thermometer in a vertical position. You may replace the calibrated thermometer when the CMRV has cooled to 30°C or lower. If the thermometer is not in place during CMRV-4500 cooling, you should seal the thermometer well in the block and the thermometer hole in the Plexiglas® cover with stoppers, particularly when the humidity of the ambient air is high. This will help prevent frost buildup on the surface of the block and enhance temperature control.

Be sure the thread is properly wound around each rotor and the Plexiglas cover is in place on top of the CMRV-4500 before proceeding with the test.

Use the VISCPRO

software to input calibration information as follows:

1. Load the VISCPRO software and make certain that the MR V instrument is listed on a button bar at the bottom of the Primary Window. If it is not, click Poll for Instruments from the Main menu to establish computer contact with the CMRV unit.

2. Click Service/Calibrate Cell Constants. The Calibration Param- eters window will open.

3. Click the Temperature field and select the desired calibration temperature from the drop-down options.

4. Click the Mass field and select the correct value for the test mass.

5. Click the Known Viscosity field and input the known viscosity of the standard at the calibration temperature in centipoise (mPa·s).

6. Click the Calibrate ... button to open the

Calibrate Cell Constants window. The

CMRV-4500 will cool to the desired calibration temperature and maintain the temperature for one hour. When the instrument has completed the calibration profile, the Status field in the Calibrate Cell

7. Remove the Plexiglas® cover and align the pulley-wheel with the cell to be calibrated.

8. Place the thread from this cell over the pulley-wheel. Hook the calibration weight specified by the Method to the end of the thread (see photo).

9. From the Calibrate window, click the desired cell number for calibration.

10. Press the blinking Start Test button on the CMRV controller.

11. Raise the locking pin quickly and smoothly. The weight will apply torque to the rotor. The computer will record the time for three complete revolutions.

12. Permit the wheel to make at least three complete revolutions (the viscosity LED will go out). Then catch and remove the 150-gram weight before the thread is completely unwound. Do not permit the thread to completely unwind.

Limiting calibration time

NOTE

After the rotor revolution time has been recorded, the program will calculate the calibration constant for that cell.

13. At the conclusion of the test, the VISCPRO® software will display the newly-calculated calibration constants.

If the new constants vary from the previous cell constants by more than 4 percent, an error will be generated. It is generally advisable to recalibrate the cell in this instance.

View Cell Constants.

14. Repeat the above calibration routine for the remaining cells.

It is recommended that you perform the cell calibration immediately following the one-hour sample soak time. Although CANNON® viscosity standards N105B and N400B have been dewaxed to a very low temperature, the standard should not be allowed to soak at -20°C for more than two hours. The small amount of wax which may be in the oil could cause an error in calibration.

If any cell has a calibration constant more than 10 percent higher or lower than the average for the other cells, the fault may be excessive friction in the upper bearing, improper seating of the lower bearing, or a damaged rotor tip. Examine the rotor for damage and, if necessary, replace the rotor and recalibrate the cell.

ASTM D 3829 method

ASTM D 4684 method

SUMMARY OF TEST PROCEDURE

In the ASTM D 3829, ASTM D 4684 and ASTM D 6821 test methods, a 10-ml sample is placed in a test cell, pre-heated to a specified temperature, and held at that temperature for a specified time to ensure complete solution of all components of the oil. The temperature of the cell is then lowered to the test temperature at a programmed cooling rate. The test temperature and the cooling program (profile) are determined by the nature of the sample being tested and by the test method being used.

ASTM D 3829 uses slow cooling followed by a soak period at the test temperature and requires about 19 hours for completion of the entire test. The test is designed for engine oils.

ASTM D 4684 uses much slower cooling and requires between 45 and 54 hours for completion of the test. (The D 4684 temperature cycle is sometimes referred to as the TP-1 cycle.) The test is designed for engine oils.

ASTM D 6821 method

ASTM D 6896 method

NOTE CANNON may provide copies of a relevant ASTM Method with your CMRV

ASTM D 6821 uses slow cooling and requires about 18 hours for completion of the test.The test is designed for drive line lubricants.

ASTM D 6896 uses slow cooling and requires between 43 and 45 hours for completion of the test. This test method covers the measurement of the yield stress and viscosity of used diesel oils.

instrument purchase. The ASTM D 6821 method is currently provided with any order for the special drive line rotors available for the MRV. Additional reprints of the ASTM test methods may be purchased from:

ASTM 100 Barr Harbor Drive West Conshohocken, PA 19428

The CMRV-4500 determines the yield stress and apparent viscosity of the sample by measuring the rotational speed of a cylindrical rotor immersed in the sample in the test cell. For ASTM D 3829, yield stress is measured by adding 10-gram disks successively until discernible rotation occurs. Apparent viscosity is then determined by measuring the angular velocity of the rotor when a 150-gram weight is applied.

ASTM D 4684 method

CANNON

ASTM Method D 4684 describes the procedure for measuring yield stress and apparent viscosity . Yield stress is an indication of a structure that has formed within the oil under the cooling conditions of the test.

NOTE

Most commercial oils do not have a yield stress when tested as specified by the SAE J300 Viscosity Classification.

For the complete, definitive description of the ASTM D 4684 method, see the provided and Apparent Viscosity of Engine Oils at Low Temperature, Designation: D 4684, also available in the Annual Book of ASTM Standards, Volume

05.03.

NOTE

Nothing in this manual is intended to supersede the provisions of the ASTM test method.

The cooling cycles used in the ASTM D 4684 test method are sometimes referred to as the TP-1 cycles. For details, see ASTM D 4684 and Henderson, K. O., Manning, R. E., May , C. J., and Rhodes, R. B., “New Mini-Rotary V iscometer Temperature Profiles That Predict Engine Oil Pumpability ,” SAE Paper No. 850443.

Required test time

The ASTM D 4684 temperature program (profile) requires 45 to 54 hours to complete, depending on the final test temperature. Additional time is required to perform yield stress and apparent viscosity measurements.

ASTM D 3829 method

Standard Test Method for Determination of Yield Stress

For the complete, definitive description of this method, see the provided Standard Test Method for Predicting the Borderline Pumping Temperature of Engine Oil, Designation: D 3829, also available in the Annual Book of ASTM Standards, Section 5, Volume 05.03.

NOTE

Nothing in this manual is intended to supersede the provisions of the ASTM test method.

ASTM Method D 3829 offers the option of reporting that the BPT (borderline pumping temperature) is below a certain temperature. The temperature control profiles for the CMRV-4500 are designed to run the test at the limiting BPT for each viscosity grade. Thus, viscosity or yield stress values must be below the critical values for an oil to be acceptable.

The temperature profile for this method consists of a 2-hour soak at 80°C ± 3°C, a 10-hour nonlinear cool-down to the test temperature, and a 6hour soak at the test temperature. The entire temperature profile, up to the point of measuring yield stress and viscosity , requires about 18.5 hours.

ASTM D 6821 method

For the complete, definitive description of this method, see the provided Standard Test Method for Low Temperature Viscosity of Drive Line Lubricants in a Constant Shear Stress Viscometer, Designation: D 6821.

Page 63

The temperature profile for this method consists of a 1.5-hour soak at 50°C ± 1°C, a 2-hour nonlinear cool-down to the test temperature, and a 14-hour soak ± 0.02°C at the test temperature. The entire temperature profile, up to the point of measuring yield stress and viscosity , requires

17.5 hours.

ASTM D 6896 method

For the complete, definitive description of this method, obtain a copy of the Standard Test Method for the Determination of Yield S tress and Apparent Viscosity of Used Engine Oils at Low Temperature, Designation ASTM D 6896.

This test method covers the measurement of the yield stress and viscosity of used diesel oils after cooling at controlled rates over a period of 43 or 45 hours to a final test temperature of -20 or -25°C. The viscosity measurements are made at a shear stress of 525 Pa over a shear rate of 0.4 to 15 s-1. This method is suitable for measurement of viscosities ranging from 4,000 mPa-s to 400,000 mPa-s, and is suitable for yield stress measurements of 7 Pa to >350 Pa. The Method is quite similar to ASTM D 4684 except that the preheat phase is accomplished in an oven (not provided with the CMRV) immediately prior to commencing the temperature profile.

SAE J300 notes

SAE Standard SAE J300, Engine Oil Viscosity Classification temperatures, specified according to the viscosity grade, are as follows:

SAE Viscosity Grade Low-Temperature Pumping Viscosity

Source: SAE J300 Revised DEC99

NOTE The user of the CMRV-4500 is advised to be alert for revisions of the

SAE J300 Viscosity Classification.

Delayed start option

Because of the length of the profile, the starting time should be chosen so that the test temperature will be reached at a convenient time for testing. The delayed start option is quite useful for starting the cooling cycle over a weekend or holiday in preparation for running samples on the following business day. For details, see Chapter 10.

Test preparation

Procedure

NOTE

RUNNING PROFILES

The guidelines in this section are not intended to supercede any test method. Always refer to the method for validation of any test procedure.

T o run a temperature profile, first prepare the CMRV -4500 for testing (see Chapter 6). Make sure that the Air/Water Heat Exchanger POWER switch is on and that the unit is operating normally .

1. Place 10 ml of test oil in each of the viscometric cells to be used. Any number of cells, one to nine, may be used but all test oils for the run must be for the same test temperature. Use a syringe or small plastic cup to fill the cells.

If testing with fewer than nine cells, fill unused cells with 10 ml of a clean oil prior to running the test.

2. Load the VISCPRO® software and click Main/View Instrument. Select the desired instrument type (MRV) and configuration from the View Instrument window. Then click OK.

NOTE

CAUTION

3. Record the sample ID for the first calibrated MRV cell by clicking in the Sample ID field and typing the sample name. Then press the Tab key to move the cursor to the next Sample ID field (or just click in the desired ID field). Repeat the process until ID information has been entered for all test samples.

4. (optional) Save your MRV instrument configuration by clicking Main/Save Instrument. Select your instrument type (MRV) and enter a name for the configuration in the Save As: field. Then click OK to save the configuration.

You may change the Sample ID at any time prior to initiating the Yield Stress or Viscosity tests. If you change the sample information, you may wish to save the configuration (see step 4, above) before closing the Instrument View window or your changes may be lost.

5. Carefully insert the rotors into their corresponding test cells, making sure that the rotor tip at the bottom of the shaft slides into the recess at the bottom of the cup.

Do not drop the rotors into place or you may damage the rotor tips.

6. Secure each rotor in position with a rotor bearing pin.

Winding rotors

7. To wind the rotors in preparation for the profile, slide the pulleywheel assembly along the track until the pulley is aligned with the first viscometric cell. Use the engraved lines on the slide bar as a guide to determine the proper position of the left side of the pulleywheel block.

8. Place the loop of a thread over the left end of the crossbar at the top of the rotor shaft.

9. Pass the free end of the thread (the end with the plastic ring) over the pulley-wheel and allow it to hang freely in front of the viscometer. While holding the rotor motionless, hook a light weight, such as a large paper clip, on the plastic ring to apply slight tension to the thread.

10. Guiding the thread with your finger, turn the rotor clockwise to wind the thread above the crossbar until the knot in the loop has been wound around the rotor shaft. Then pass the thread below the crossbar and continue turning the rotor clockwise (as viewed from above) to wind 20 closely spaced turns of thread around the shaft below the crossbar without overlapping the turns. About 200 mm (8 inches) of thread will remain. Place this remaining length of thread over the upper bearing support plate so it hangs to the rear of the viscometer and secure the rotor in place by lowering the rotor locking pin over the rotor crossbar. You may need to turn the rotor slightly to align the crossbar with the locking pin.

Plexiglas

cover placement

CAUTION

11. Repeat steps 8-10 for each of the remaining rotors/cells.

12. Place the Plexiglas

cover in position over the top of the viscometric cells (see photo). The small hole which allows the

-46 to 30°C thermometer to extend through the cover should be on the left when viewed from the front of the viscometer.

CMRV 4500 with rotors wound and Plexiglas® cover in place.

If a thermometer is not in place during CMRV-4500 testing, you should seal the thermometer opening in the Plexiglas® cover, particularly when the humidity of the ambient air is high. Otherwise, moisture may condense and freeze on the top of the block.

13. CMRV users following the ASTM D 4684 or ASTM D 3829 methodology should insert a flexible 3/16"-OD tube from their dry gas supply and regulator through the dry gas purge in the Plexiglas

Instrument Status window

Removing thermometer

During the profile, the Instrument View window will display the current status of the profile, the current test temperature, the desired temperature, time elapsed, and the time remaining until the yield stress and viscosity tests should be run. Display data is normally updated every 0.5 seconds. The following status options are available:

RED–Fatal Instrument Fault (unlikely); Instrument stops responding to queries for more than 60 seconds (or 385 seconds during a Viscosity Test) YELLOW–Instrument Warmup (displayed for 45 minutes after turning on instrument). During this time, instrument calibration cannot be performed. A test can be run on a calibrated instrument only if the “Ignore Instrument Warmup” box is checked in the instrument view. GREEN–Normal Instrument Operation

T o reduce the chance of separating the mercury column, you may wish to remove the calibrated thermometer from the CMRV unit prior to running a cooling profile. Store the thermometer in a vertical position. You may replace the calibrated thermometer when the CMR V has cooled to 30°C or lower. If the thermometer is not in place during CMRV -4500 cooling, you should seal the thermometer hole in the Plexiglas® cover, particularly when the humidity of the ambient air is high. Otherwise, moisture may condense on the top of the block.

Verifying temperature

Tolerance problems

Completing CMRV tests

NOTES

When the profile has concluded, verify the temperature reading and then measure the yield stress and viscosity .

If the CMRV instrument fails to maintain temperatures within required tolerances during the profile, the MRVW software will display a warning. The profile will be completed, but displays and printouts of CMRV data will indicate that the profile was out of tolerance.

Viscosity and yield stress tests should be completed shortly after the completion of the profile.

ASTM D 4684 requires completion of yield stress and viscosity tests within 30 minutes of the conclusion of the profile.

If, at the conclusion of a test, the block temperature is more than 0.2°C cooler or warmer than the specified test temperature then the test may not conform to ASTM D 4684 or ASTM D 3829 requirements. Consult the appropriate ASTM method for additional information. If the test is out of tolerance the temperature probe may have to be recalibrated and the test rerun to obtain reliable readings for the desired temperature. Yield stress and viscosity tests may still be performed for the samples, but the calculated values will be indicative of the actual temperature at the end of the profile, not the desired temperature.

Adjusting temperature at the end of a profile

In the event that the CMRV instrument fails to attain the desired temperature at the conclusion of a profile, it is possible to adjust the instrument temperature using the following procedure:

1. Wait until the profie is completed and the Temperature Correction button is active.

2. Click in the Thermometer Temperature field and type the current temperature (as indicated by your calibrated thermometer) to the nearest 0.1°C in the Thermometer Temperature field. Make certain to use the minus (-) sign for subzero temperatures.

3. Click the Temperature Correction button to enter the temperature reading.

NOTE

If you input a temperature but do not click the Correction button, the input temperature value will be stored in the database as the actual temperature for the test.

4. Wait for the instrument to stabilize at the new temperature for the desired time period.

5. Continue with the Y ield S tress and Viscosity test procedures.

NOTES

The Temperature Correction button option is only active at the conclusion of the temperature profile and prior to yield Stress or Viscosity testing.

If the amount of the Final Temperature adjustment is greater than the tolerances specified in the profile, the temperature probe and CMRV cells should be recalibrated per the manual procedure.

If you do not enter a Thermometer Temperature, the final profile temperature will be recorded as the actual temperature for the test(s).

2. Slide the pulley-wheel assembly along the track until the pulley is aligned with the left side of the shaft of the appropriate rotor. Use the engraved lines on the slide track to determine the proper position of pulley wheel block relative to the rotor.

3. Make sure that the pulley-wheel sensor wire is placed in a position to prevent its interference with the falling hook-cage/weight during yield stress/viscosity testing.

4. Place the rotor thread over the pulley-wheel with the plastic disk hanging in front of the viscometer block and over the edge of the table.

5. Hang the hook-cage on the ring at the end of the thread.

ASTM D 3829 and 4684 specify an initial weight of 10-grams, and increase of weight in 10-gram increments. ASTM D 6821 specifies an initial weight of 2.5 grams and increase of weight in 2.5-gram increments.

6. Ensure that a Sample ID has been entered for each sample. Then click

for the desired sample. OR use the Tab key to highlight

the yield stress icon and then press R. The Yield LED (lightemitting diode) on the CMRV-4500 will glow and the Start Test

button will begin flashing rapidly.

7. Press the flashing Start Test button on the CMRV front panel and proceed immediately to step 8.

8. Slide the rotor locking pin upward to its detent position, allowing the weight/hookcage to hang free. The Yield LED will flash as the CMRV microprocessor measures the wheel rotation (See Notes on yield testing on the next page regarding the ASTM D 4684 method). If no yield stress is observed (sufficient rotation), the blinking Yield Stress light on the instrument front panel will turn off. If it does, conclude the test by lowering the locking pin to prevent the rotor from further rotation.

Adding a 10-gram weight to the hook-cage during yield stress test

NOTES

CAUTION

CANNON

9. (Optional) If there is insufficient movement of the rotor during the 15-second sampling period, follow the screen prompts to add weight to the hook-cage per ASTM methodology (see photo). The CMRV4500 will calculate the range for the yield stress value. If there has not been adequate movement of the rotor by the time the weight load reaches 100 grams, the MRVW software will calculate a minimum value in Pascals for yield stress.

When adding weights to the hook-cage, support the hook cage with one hand while keeping some tension on the thread. When releasing the hook cage use a smooth downward motion of the hand to prevent the hook-cage from swinging back and forth and to avoid jarring the rotor.

To view test results as soon as they have been recorded in the database, open an MRV Data Table analysis with the Use Dynamic Update option (see Chapter 13).

Make sure to wait for the CMRV software prompts before adding additional weights.

10. If testing viscosity for the sample, follow the directions for viscosity testing (see Measuring Apparent V iscosity, next page).

11. Repeat steps 1-10 to perform yield stress/viscosity tests for all remaining cells to be tested in order from left to right.

Notes on yield stress testing

 Step 9 (see previous section) is required for ASTM D 3829.  The ASTM D 4684 method is a pass-fail method for fresh oils. If the

rotor fails to move with the weight of the 10-gram hook-cage, the oil has failed the test. However, the MRVW program permits adding of additional weights. If this alternate method is preferred, continue with the procedure as described in step 9. Otherwise, click the Abort Test button to abort yield stress testing on that cell.

NOTE

Do not abort CMRV temperature control until you have finished all yield stress and viscosity tests for the cells.

 Pulley-wheel motion is detected by the digital-optical sensor. Ad-

equate rotor movement is defined as 13° of rotation for ASTM D 4684 and ASTM D 6821 (This is equivalent to 3 mm of motion by the crossarm). For ASTM D 3829, 10° of rotation is required.

 If yield stress testing on a cell is aborted before adequate rotor

movement is detected, the resultant calculated yield stress will be based on the highest weight used. For example, if the operator aborts a yield stress calculation after testing with a total of 30 grams with no rotor movement, the CMRV software will report yield stress greater than 105 Pascals (Y>105).

Measuring apparent viscosity

After the yield stress test has concluded, you may measure apparent viscosity using the procedure below:

1. Place the pulley-wheel in line with the appropriate viscometric cell and place the rotor thread over the pulley-wheel.

NOTE

CANNON

ASTM methodology requires testing the samples in sequence from left to right.

2. Ensure that a Sample ID has been entered for each sample. Then click

for the desired sample. OR use the Tab key to highlight

the desired viscosity test icon and then press R. The Viscosity LED (light-emitting diode) on the CMRV-4500 will glow and the Start Test button will begin flashing rapidly.

3. Carefully place the large hook-weight on the end of the thread (see photo, next page), supporting the weight with your hand to prevent rotation of the rotor.

5. Press the flashing Start Test button and proceed immediately to step 6.

6. Lift the locking pin and release the weight by lowering your hand quickly and smoothly.

The CMRV-4500 will measure the speed of rotor rotation by timing the revolution(s) of the pulleywheel as the weight falls.

NOTE

CAUTION

The total number of rotations measured by the CMRV-4500 during the viscosity test depends on the viscosity of the sample and the values chosen in the Advanced Settings box. Default values for the Advanced Settings correspond to the specifications of the ASTM method selected for the profile.

7. When the Viscosity LED on the CMRV front panel stops flashing, indicating the conclusion of the viscosity test, remove the hook-weight

from the string.

Do not remove the weight while the Viscosity LED is still flashing.

To view test results as soon as they have been recorded in the database, open an MRV Data Table analysis with the Use Dynamic Update option (see Chapter 13).

8. To test additional cells, repeat steps 1-7 above, testing in order from left to right.

After all viscosity tests have been concluded, select End Profile from the Instrument View window to terminate temperature control of the CMRV.

NOTE

No further testing can be conducted after temperature control has been aborted.

Notes on viscosity testing

Do not let the large hook-weight swing back and forth during testing or the apparent viscosity measurement may be distorted.

Cooling profile limitations

CMRV cooling capacity

Correcting profiles

The CMRV cooling capacity changes proportionally with the temperature at which the instrument is controlling. Greater cooling capacity is achieved at warmer temperatures, and capacity decreases as temperature decreases. This makes linear rates-of-cooling impossible in relatively short time frames.

If the rate-of-cooling for a profile exceeds the cooling capacity of the instrument, one of three things must be done:

 Lengthen the time between the two fixed temperature points  Decrease the temperature change between the two fixed times  Apply a combination of the two previous options.

When a profile data point with a specified tolerance is entered in the Profile Designer, software calculations are automatically made to determine if the rate-of-cooling relative to the previously-entered point is within the instrument’s capability. It is assumed that the instrument can achieve the temperature specified by the previous point. If no tolerance is specified for that point, then this assumption may or may not be warranted. For this reason, it is possible to design a profile that the instrument is incapable of achieving. The software will only flag those points that are absolutely impossible to realize. This suggests that experience and experimentation are needed to properly design profiles which can be run successfully .

NOTE

The ASTM D 3829 and ASTM D 4684 profiles supplied with the MRVW software define non-toleranced points which are outside of the instrument’s capability, but these are merely necessary stepping stones which permit the instrument to attain proper temperature control at the subsequent temperatures that are toleranced.

Profile Designer test parameters

The Profile Designer displays important test parameters for Yield Stress and Viscosity testing. These values are editable from the Profile Editor. For all ASTM profiles in the profile library, these values have been preset in conformity with current ASTM specifications.

NOTE

When the user is designing an entirely new profile “from scratch”, the test parameters will default to ASTM D 4684 specifications. Copies or modifications of standard profiles will default to the parameters associated with the ASTM method (D 3829 or D 4684).

Changing test parameters

1. Open the Profile Designer.

2. Select the desired profile and click the Create ..., Copy ... or Edit ... button as desired. The Profile Editor window will open.

3. Enter appropriate test parameter values. See the chart below for information on default test parameters.

5. Make any other necessary changes to the profile; then save the profile by clicking the Save button from the Profile Editor window.
