1 ABOUT YOUR TESTER
The Elcometer 110 Pneumatic Adhesion Tester is a simple-to-use instrument for measuring the bond strength between a coating and a substrate.
The tester uses a pneumatically operated piston to apply a tensile force along the axis of a pull stub which has been glued to the coating. The tester mea sures the pressure in the piston during the test and records the pressure at the point of coating failure or at the point when the test is stopped.
The values obtained provide a quantitative mea sure of the strength of the bo nd between a coating and its substrate or the strength of an adhesive.

2 GETTING STARTED
2.1 Basic principle of operation
An aluminium pull stub is glued to the test surface. When the glue has fully cured, a pulling piston is attached to the pull stub (Figure 2).
A reservoir inside the control module is pressurised by a CO
cartridge or by a
2
compressed air line. The control module is connected to the pulling piston by a hose. The control module applies increasing pressure to the pull stub until it becomes
detached from the test surface or until the test is stopped. The control module registers the maximum pressure (psig) attained and this
value can be converted to bond strength (POTS) - see “Piston burst pressure to POTS conversion” on page 17

F20 Piston
The F20 piston (Figure 6) differs from the standard pistons as it has two piston gaskets. The compressed air supply to each of th e gaskets can be switch ed on or off, therefore allowing the piston to be used as:
an F8 piston (air supply to inner gasket only)
an F12 piston (air supply to outer gasket only)
or as an F20 piston (air supply to inner and outer gaskets) To switch off the air
supply to a gasket, remove the gasket to reveal the tapped hole in the piston housing. Insert into this hole one of the two screws with O-ring supplied with your piston and tighten gently.

2.4 Power supply
Your Elcometer 110 Pneumatic Adhesion Tester is powered by a single 9 V dry cell battery or direct from the m ains electricity using the optional external powe r supply.
To fit the battery, slide open the battery compartment at the rear of the tester and insert the battery taking care to observe the corr ect polarity. Slide the battery compartment closed when you are finished.
If appears on the display, change the battery.
Plug the optional power supply into the mains outlet an d connect the lead to the socket marked ‘9 V DC in’ on the rear of the control module. There is no need to remove the battery while the tester is powered from the mains.
3 SAFETY PRECAUTIONS
USE EXTREME CAUTION WHEN CARRYING OUT PULL OFF TESTS.
Due to the high pressures utilised (up to 100 psi), pieces of the test sample or apparatus may fragment, and consequently, safety precautions should be followed at all times.
The control module should be as far removed as possible from the surface under test (i.e. the full length of the connecting hose).
Pull off may occur at any pressure level. At pull off point the piston (with the pull stub attached) will be forced upwards from the test surface. Consequently, while waiting for pull off to occur you must not lean over, or place any part of your body over, the test surface.
When releasing pressure from the system (see page 16), ensure that your face is not over the piston.
Use extreme caution when disconnecting hoses while the system is pressurised (see page 16).

4 PREPARING FOR A TEST
4.1 Attaching the pull stub to the coating
These instructions describe the use of Araldite epoxy resin to attach the pull stub to the coating. Use of other adhesives may require different surface preparations and/or application techniques. Please refer to the relevant manufacturers recommended procedures.
1. To ensure good adhesion, the pull stub and test surface must be clean and free from debris and contaminants e.g. skin oils etc. Any recognised method for cleaning and degreasing aluminium may be used. Apply an adhesive mask to each test surface.
2. Mix the epoxy. Apply to the blast cleaned end of the pull stub and some to the middle of the mask, press it into the roughened surface of the pull stub to fill the voids.
Note: Ensure no epoxy gets onto the threaded part of the pull stu b.
R
3. Press the epoxied end of the pull stub to the epoxied area of the test surface guide the pull stub to the centre of the adhesive mask and maintain pressure for approximately 1 minute.
Figure 7. Attaching a pull stub to the coating
DO NOT rotate or tilt the pull stub in relation to the test surface as this will create voids in the epoxy. If this does happen, remove the pull stub immediately, remove all residual adhesive, restore the blast cleaned (roughened) surface and re-attach the pull stub to the test surface.
4. Allow the epoxy to fully cure (24 hours at room temperature).

R
4.2 Preparing the control module
1. Attach the connecting hose to the piston outlet on the front panel of the control module.
2. Switch the instrument on by rotating the Off/On control.
3. Reset the instrument; press and hold the Reset button, then release.
4. Bleed any residual pressure in the connecting hose by pressing the stem in the centre of the connector carefully. Then push Reset, and at the same time turn the Zero Reset spindle on the back panel of the control module until the digital piston pressure gauge reads 00.0. Release Reset.
4.3 Pressurising the system
The system must be pressurised before it can be used. When the system is fully pressurised (170 psig), sufficient gas is available for 5 tests using the F4 piston at a maximum pressure of 100 psig.
The system can be pressurised using any of the following techniques:
•CO
cartridge + standard cartridge holder.
2
Compressed air supply using optional hose assembly.
•CO
cartridge + optional trigger inflator.
2
4.3.1 Pressurising using the standard cartridge holder
1. Fit the cartridge into the cartridge holder and screw it into the inlet marked ‘CO
cartridge’ on the rear panel of the control module until resistance is
2
felt.
2. Continue screwing the cartridge holder until the cartridge is pierced and the gas is heard to flow into the control module.
The analogue supply pressure gauge will indicate the pressure. Excess pressure (above 170 psig) will escape through the relief valve inside the control module; the analogue meter re ading should drop to approximately 170 psig.
3. Unscrew the cartridge holder and disp ose of the empty CO
cartridge.
2
4.3.2 Pressurising using a compressed air supply
The system can be pressurised from an external compressed air supply (compressed air line, compressor, bottle, etc). Ensure that the maximum pressure of the supply is regulated to a maximum of approximately 100 psig.
1. Use the optional connecting hose assembly (part number T11013455 - see “Accessories and spare parts” on page 18) to connect the compressed air
10
supply to the inlet marked ‘air-line in’ on the rear panel of the control module.
2. Open the compressed air supply valve to pressurise the control module. The analogue supply pressure gauge will indicate the pressure. The compressed air supply can be left connected to the control module
during testing.
3. When you have finished testing, close the compressed air sup ply valve and remove from the inlet at the rear of the control module.

4.3.3 Pressurising using the trigger inflator (optional item)
The trigger inflator is available as an optio nal accessory - see “Accessories a nd spare parts” on page 18.
1. Non-threaded cartridges: Unscrew and remove the handle of the trigger inflator and insert the cartridge into the handle with the narrow end up. Screw the handle slowly onto the body of the trigger inflator until the cartridge begins to make contact with the puncture pin. Without depressing the trigger, quickly and firmly continue to screw the handle to puncture and then seal the cartridge (Figure 8).
Figure 8. Inserting a non-threaded
cartridge
Threaded cartridges: Unscrew
and remove the handle of the trigger inflator. Screw the cartridge slowly into the valve body until the cartridge begins to make contact with the puncture pin. Without depressing the trigger, quickly and firmly continue to screw the cartridge to puncture and then seal the cartridge (Figure 9).
2. Screw the outlet of the trigger
Figure 9. Inserting a threaded
cartridge
inflator onto the inlet mar ked ‘a ir­line in’ on the rear panel of the control module.
3. Depress the trigger of the inflator to pressurise the control module. The analogue supply pressure gauge will indicate the pressure. Excess
pressure (above 170 psig) will escape through the relief valve inside the control module; the analogue meter re ading should drop to approximately 170 psig.
4. Unscrew the outlet of the trigger inflator from the inlet at the rear of the control module. If the CO otherwise retain for future use.

4.4 Preparing the piston
1. Rotate the Rate control on the front panel of the control module to 0.005.
Note: The closed position is 0.000. Do not overtighten the Rate control as this may damage the valve inside the control module.
2. The run rate can be adjusted finely if required, by turning the Rate control by small increments.
R
To apply a tensile force increasing at a constant rate of less than 1 N/mm per second (150 psi/s), but to reach full force in less than 100 seconds, the run rate should be adjusted to be within the times shown in Table 1. This should be done with the appropriate piston attached.

3. Press and hold Reset to reset the digital meter to 00.0. The time taken to reset is relative to the time taken for maximum pressure to be reached in step 2 above.
4. Attach the piston hose to the valve on the connecting hose (Figure 5).
5. Remove the black reaction plate (removing the pull stub from the centre of the piston) to expose the gasket and then press the Run button.
6. The piston gasket must be push ed out using less than 3 psig. If not, remove the piston gasket from the piston housing being careful not to scratch the vertical walls of the piston housing. Wash the gasket with detergent and water solution. Wipe dry and lubricate the gasket and piston housing with a light coating of pure talcum powder.
7. Replace the gasket into the piston housing carefully; the concave surf ace must face into the housing.

5 PULL OFF TEST PROCEDURE
Before you start a test, the adhesive between the pull stub and the coating must be cured. Prepare the instrument and piston - see “Preparing for a test” on page 9.
5.1 Pull off test
If the adhesion need only be tested to a specified pull off tensile strength (POTS), the pressure must be determined by the burst pressu re (BP) to POTS Conversion Table - see “Piston burst p ressure to POTS conversion” on page 17 The test is only successful if pull-off does not occur up to and including the specified POTS.
For best accuracy a piston that pulls off at a high burst pressure (greater than 60 psi) should be selected.
1. Ensure the metal protection washer inside the piston body is in place.
2. With the felt-coated side down wards, p lace the sele cted piston over the pull stub.
3. Thread the reaction plate onto the pull stub until light contact is made with the piston. Note this orientation.
14
Figure 10. A test in progress
4. Unscrew the reaction plate through 90° from the point of contact. This will allow gasket sealing and alignment of the reaction plate perpendicular to the pull stub axis.
5. The digital piston pressure gauge should read 00.0. If not, adjust the zero setting by holding in Reset and at the same time turning the Zero reset control on the back panel of the control module. Then release Reset.
6. Press and hold Run until the piston assembly (with attached pull stub) detaches from the surface (pull-off point), or 100 psig is attained.
7. Release Run.
5.1.1 If pull-off has occurred
1. Using extreme caution, unscrew the connector hose from the piston assembly and bleed any residual pressure by pressing the stem in the centre of the hose valve fitting.
2. Unscrew the reaction plate from the piston and remove the pull stub.
3. Record the maximum pressure as indicated on the digital piston pressure gauge (using correct mathematical rounding), the piston size and nature of failure.
R
4. Convert the pressure reading to adhesion strength by referring to the appropriate Piston Burst Pressure to POTS Conversion Tables.
If you want to carry out further tests, ensure the system is still correctly setup (Section 4) and then repeat Section 5.1.
If the pressure on the analogue meter has dropped below 100 psi it is advisable to re-pressurise the system (Section 4.3) before attempting further pull off tests.
5.1.2 If pull-off has not occurred
If pull-off is required and maximum pres sure does not detach the pull stub, it indicates either:-
Too small a piston has been used. Disconnect the connecting hose from the piston hose, remove the reaction plate and then remove the piston from the pull stub.
Ensure the system is correctly setup (Section 4) and then repeat Section
5.1 using the next largest F piston.
There is insufficient pressure in the system. Repressurise the system and repeat Section 5.1.
15
R
5.2 After the test
It is safe to leave the system pressurised between pull off tests. However, if the instrument is to be transported, or left unused for a long period of time, it is advisable to shut down (depressurise) the system.
1. If using a regulated gas supply, close the main valve on the supply.
2. If pull-off has not occurred, disconnect the connecting hose from the piston hose, remove the reaction plate and then remove the piston from the pull stub.
3. Reconnect the piston hose connector to the connecting hose to allow the system to vent.
4. Open the Rate control on the front panel of the control module (turn it anti­clockwise) to increase the speed of venting.
5. Press and hold Run until the analogue pressure gauge reads 0. Pressure will vent from the piston causing the piston gasket to extrude.
6. Disconnect the connecting hose from both the piston assembly and the control module.
7. Tu rn the instrument off to conserve battery life.
6 RECORDING THE PULL OFF TEST
Your tester includes an interface (recorder output) at the rear of the control module which allows the pressure during a test to be monito red or recorded.
To use this facility, insert the 3.5 mm jack plug (included) into the recorder output terminal on the back of the control module and connect it to your Chart Recorder. This will record the pressure used during the test, but does not record the displayed pull off point value.
Note: The tip of the 3.5 mm Jack Plug is positive an d th e cas e is ne gative . The output ranges from 0 mV DC to 100 mV DC for 0 psi to 100 psi pressure.
The control module output is a differential signal via 2 x 1 kΩ resistors and therefore a measuring instrument with 200 kΩ input impedance or higher must be used to ensure the reading is within 1% of the display.
16
7 PISTON BURST PRESSURE TO POTS CONVERSION
POTS = Pull Off Tensile Strength (psi or N/mm²) BP = Burst Pressure (psig) (digital piston pressure gauge reading)
Each piston is supplied with a Burst Pressure to Pull Off Tensile Strength Conversion Table for a Standard Pull Stub of 12.7 mm (½") diameter.
Using the Conversion Tables
When using a BP to POTS Conversion Table, a burst pressure of 55 psig from the digital piston pressure gauge converts to a POTS reading on the Table where row 50 and column 5 intersect.
Non-Standard Pull Stub POTS
Non-standard pull stub POTS readings must be adjusted to allow for the change in the pull stub area. To do this, divide the POTS reading by the non-standard pull stub area; then multiply this figure by the standard pull stub area.
R
Note: Standard Pull Stub area is 126.7 mm² (0.196 square inches). The Standard Pull Stub diameter is 12.7 mm (½").
8 STORAGE
This instrument uses a Liquid Crystal Display. If it is heated above 50°C (120°F) it may be damaged. For instance, this can happen if it is left in a parked car in strong sunlight.
Remove the battery from the instrument if it is to remain unused for a long period of time. This will prevent damage to the instrument in the event of malfunction of the battery.
