3. Measurement

Table of Contents

3.1 Performing Measurements

3.1.1 Leeb Testing Procedure (except Leeb U)
Select automatic compensation for impact direction “Automatic”, see chapter “3.2.1 Controls”. If “Automatic” is not allowed, set the impact direction (         ). The Equotip Leeb Impact Devices DL doesn’t sup­port automatic mode. The impact direction must be selected manually.
Select the appropriate material group, hardness scales and number of impacts per measurement series. For more information see chapter “4. Settings”. Conduct impacts by cycling through “load, position and trig­ger” mechanism:
1. Load the impact device – while not in contact with the test piece – by hold­ing it firmly with one hand and sliding the loading tube with the other hand until contact is grabbed by the clutch.
2. Position the support ring on the test piece. Take particular care to fully position the support ring on the test piece, but not coinciding with a previ­ous test indentation.
3. To trigger an impact, press the trigger button to release the impact body. To perform another impact, repeat this cycle.
Figure 4: Leeb Testing Procedure
After the last of the impacts is performed, the hardness average and fur­ther statistics of the measurement series are displayed.
NOTE! Make sure the loading tube is allowed to slowly return back to the starting position. Do take care so the loading tube does not spring back uncontrolled, which may result in permanent device damage.
NOTE! If possible, follow the standard practice of Leeb re­bound hardness testing as described in the standards DIN 50156-1 (metallic materials), ASTM A956 (steel, cast steel and cast iron only), or other applicable standards. If these are not available, the user is recommended to average a minimum of n = 3 impacts at an indentation distance of 3 to 5 mm (0.12 to 0.20”) for each location of the sample that shall be tested.
NOTE! Do not carry out an impact in an area that has already been deformed by another impact. Also, do not load the device when it is already positioned in the new test location, since the material under the device may be affected through prior stress, and the catch chuck of the device may get damaged.

3.1.2 Portable Rockwell Testing Procedure
Table of Contents
1. Place the probe on the sample to test. For flat surfaces the standard foot is most suitable. For cylindrical objects it is recommended to use one of the special feet. For locations difficult to access a tripod foot can be used. See chapter “14. Ordering Information” for more details.
2. Press the probe slowly but firmly against the surface to perform the measurement. Suppress vibrations as much as possible, and follow the instructions on the screen.
3. Release the probe when the instru­ment says so. Again, this movement has to be done in a controlled man­ner. If the probe is released too fast, a warning will be shown and the measurement should be repeated.
Figure 5: Portable Rockwell Testing Procedure
3.1.3 UCI Testing Procedure
1. Place the probe on the sample to test. The probe must be perpen­dicular to the surface (± 5°). The special foot can be used to increase repeatability and reduce distor­tion of the results, see chapter “14. Ordering Information”.
2. Press the probe slowly but firmly against the surface until the se­lected measuring force is reached. The instrument will indicate when to release the probe with an on-screen prompt and audible sound.
3. Release the probe from the mate­rial. It is important to remove the probe completely from the test object. Otherwise the results can be biased.
Figure 6: UCI Testing Procedure
NOTE! A warning will be shown if the user applied too much load when pressing the probe against the surface. Please avoid frequent overloading, as this could seriously damage the probe.

3.1.4 Leeb U Testing Procedure
Table of Contents
The Equotip 550 Leeb U enables the user to quickly and precisely diag­nose roll imperfections, hardness inconsistencies and uneven winding, thereby preventing problems for printing and converting operations.
With Equotip Impact Device Leeb U automatic impact direction mode is not supported and the user must select the appropriate impact direction manually (90° down, 45° down, 0°).
As for roll hardness testing no conversion curves are used, no material group has to be selected.
Conduct impacts by cycling through “position and trigger”.
1. Position the probe on the roll to be tested. Make sure to fully posi­tion the support ring on the roll to ensure an impact perpendicular to the test surface.
2. While holding the impact device firmly with two hands, slide the loading tube smoothly down to load and trigger an impact.
Move the impact device to the next point on the roll and repeat.
Figure 7: Leeb U Testing Procedure
NOTE! Some features mentioned in this Operating Instruc­tions are specifically addressing metal hardness testing ap­plications and therefore not available for Equotip Leeb U.

Impact Body
During measurement with Equotip 550 impact devices (D, DL, DC, C, G, S, and E); an impact body with a ball indenter is launched by spring energy against the sample to be measured, and then rebounds. Before and after the impact, a permanent magnet inside the impact body passes through a coil in which a voltage signal is induced by the forwards and backwards movement. This induction signal behaves proportionally to the velocities. The ratio of the rebound velocity vr to the impact velocity vi multiplied by 1000 yields the hardness value HL (Leeb hardness). HL is a direct measure of the hardness. The third resp. fourth letter of the HL unit refers to the impact device HLD D impact device.

Equotip Leeb U
Although the Equotip Leeb Impact Device U is constructed differently to simplify the measurement process, the underlying principle is the same.
Figure 11: Equotip Leeb U Impact Device
Existing Parotester impact devices type U are fully supported by the Equotip 550. Typ P and PG impact devices can be still used, but the unit is shown as HLU although it would be actually LP resp. LPG.
NOTE! HLU values can be directly compared to LU on exist­ing Parotester instruments.

3.3.1.2 Sample Preparations
Table of Contents
Keep the sample free of vibrations during the test. Light and thin parts must be specially fastened, see chapter “3.3.1.6 Testing Light Samples”. Ensure that the surface of the work piece is clean, smooth and dry. If re­quired, use appropriate cleaning agents for cleaning, such as acetone or isopropanol. Do not use water or any other detergent fluids.
NOTE! Please use the surface roughness comparator plate provided to estimate the average roughness of the test piece prior to testing.

3.3.1.6 Testing Light Samples
Table of Contents
If the samples are lighter than specified in chapter “3.3.1.4 Test Condi­tions” or sample sections have unfavorable mass distribution they can vibrate as the impact body hits the test point. This results in unwanted energy absorption. Such samples shall be supported by solid worktops. If the mass falls below the specific requirements but still exceeds the coupling amount then coupling it to a larger mass can help prevent vibra­tions.
The following requirements must be met for coupling:
• The contact surface of the sample and the surface of the solid support must be level, flat and ground smooth.
• The sample must exceed the minimum sample thickness for coupling. Follow the coupling procedure.
• Apply a thin layer of coupling paste to the contact surface of the sample.
• Press the sample firmly against the support.
• Push the sample in a circular motion and carry out the impact as usual, perpendicular to the coupled surface.
NOTE! Clamping may strain the sample, which can affect the hardness readings.
3.3.1.7 Testing Curved Surfaces
The instrument works properly only when the ball indenter at the front of the impact body is precisely at the end of the tube at the time of the im­pact. When concave or convex surfaces are tested, the ball indenter either does not entirely leave the test tube or comes out too far. In such cases, replace the standard support ring by a specially suited ring, see chapter “14. Ordering Information” or contact your local Proceq representative.
