2.2 T ESTING PRINCIPLE

The basic principle is: The impact object of certain weight pounds at the testing surfaceunder certain test force. Measure the impacting velocity and the rebounding velocity of the impact object respectively when it is 1mm above the testing surface. The calculationformula is as followed:

HL=1000×VB/ VA

Where,HL -- Leeb hardness valueVB -- Rebounding velocity of the impact objectVA -- Impacting velocity of the impact object

4.1 PREPARATION & INSPECTION BEFORE TESTING

4.1.1 PREPARATION FOR SAMPLE SURFACE

Preparation for sample surface should conform to the relative requirement inTable 3.- In the preparation process for sample surface, the hardness effect of being

heated or cold processing on the surface of sample should be avoided.- Too big roughness of the measured surface could cause measure error. So, the

measured surface must be metallic luster, smoothing and polish, without oilstain.

- Curved surface: The best testing surface of sample is flat. When the curvatureradius R of the surface to be tested is smaller than 30mm while use D, DC,D+15,C, E and DL type of impact device or smaller than 50mm while use G typeof impact device, the small support ring or the shaped support rings should bechosen.

- Support of test sampleSupport is not necessary for heavy sample.Medium-weight parts must be set on the smoothing and stable plane. Thesample must set absolutely equability and without any wobble.

- The sample should have enough thickness, minimum thickness of sampleshould conform to Table 3.

- For the sample with hardened layer on surface, the depth of hardened layershould conform to Table 3.

- couplingLight-weight sample must be firmly coupled with a heavy base plate. Bothcoupled surfaces must be flat and smooth. And there should be no redundant

coupling agent exists. The impact direction must be vertical to the coupledsurface.

- When the sample is a big plate, long rod or bending piece, it can be deformedand become unstable, even though its weight and thickness is big enough, andaccordingly, the test value may not be accurate. So should be reinforced orsupported at its back.

- Magnetism of the sample itself should be avoided.

4 PREPARATION & TESTING


13/41

4.2 T ESTING

- If necessary, calibrate the TH160 with the standard test block. The accuracy andrepeatability displayed should be within the regulation of Table 5.

4.2.1 F IX PRINTING PAPER

- Hold lightly on the prismatic area at two ends of paper compartment cover bypollex and middle finger, turn the paper compartment cover upward, press printhandle fore-upwards, make paper entry at open condition.

- Put printing paper into the paper compartment, draw printing paper out and putit into the paper entry at the end of paper compartment.

- Press “Upper/paper feed” key to make printing paper feed in the cutting exit,then press down the printer handle. Hold lightly on the prismatic raised area attwo ends of paper compartment cover by pollex and middle finger and pressdown, until heard a click, the two ends of paper compartment cover fall in thelock entirely.

- If the printer handle does not return, TH160 will indicate: It can not print now.

4.2.2 S TART -UP

- Insert the plug of impact device into the socket on the tester.- Press “on/off” key, now power is connected. The tester is into testing condition.

4.2.3 L OADING

- Pushing loading-sheath downwards until contact is felt, then allow it to slowlyreturn to the starting position to lock the impact body.For DC type of impact device, place loading stick next to test area. Plunge faceof impact device(support ring side) over stick and press down till it reaches thestop position.

- Press impact device on the surface of sample firmly, the impact direction shouldbe vertical to testing surface.

12 Manual TH-160


14/41

4.2.4 T ESTING

- Press release button at top of impact device to test. The sample and the impactdevice as well as the operator are all required being stable now, and the actiondirection should pass the axis of the impact device.

- Usually, test 5 times on each measure area of sample. The data dispersionshould not be more than mean value±15HL.The distance between any two indentations or from the center of anyindentation to the edge of tested sample should conform to the regulation ofTable 6.

Table 6

Type of Impact Device Distance of center of Distance of center of thethe two indentations indentation to sample edgeno less than (mm) no less than (mm)

D,DC 3 5DL 3 5D+15 3 5G 4 8E 3 5C 2 4

- For special material, if accurate conversion from the Leeb hardness into other

hardness method is wanted, contrastive test must be done to get conversionrelations. Use inspected qualified Leeb hardness tester and corresponding otherhardness tester to test at same sample respectively. For each hardness value,measure 5 Leeb hardness values. using Leeb hardness arithmetic average valueand corresponding hardness method average value as correlative value to makeindividual hardness contrastive curve. Contrastive curve at least should include threeunits of correlative data.

4.2.5 READ MEASURED VALUE

4.2.6 PRINT OUT THE RESULT

See 6.3.3 and 6.6.

4.2.7 PRESS “ON/OFF ” TO SWITCH OFF .

4.2.8 T EST RESULT PROCESSING

Take the arithmetic average value of 5 efficient testing points as a Leeb hardnesstesting data.

4.2.9 T ESTING RESULT

- In front of Leeb hardness symbol HL, expresses the hardness value; behind HL

expresses type of impact device. For example: 700HLD expresses using D typeof impact device measured Leeb hardness value is 700.

- For other hardness method converted from Leeb hardness, put the symbol ofcorresponding hardness method in front of Leeb hardness symbol. For example:400HVHLD expresses using D type of impact device measured Leeb hardnessvalue converted Vickers hardness value is 400.

Manual TH-160 13

- Exchange the impact device in the power off condition. Otherwise it can not identifyimpact device automatically, and the circuit board of tester might be damaged.

- In normal condition, it could not print present testing value while not reachsetting Average . If want to print, press “Menu esc”key at the main display interfaceto end the testing in advance, then print.

- When the test is end in advance as mentioned above, all the functions of Autosave, Auto print and Auto transfer etc., of System set menu will not work.

- When the Impact direction was set as AUTO, if the Impact direction is or,the user need to confirm it manually.

- G type impact device has not the function of identifying impact directionautomatically. So its Impact direction can not be set as AUTO ( the cursor couldnot be moved at this symbol in the menu). If the user used other impact device andset Impact direction as AUTO , then exchanges to G type impact device, theImpact direction will be changed to? automatically.

- Only D type impact device has the function of strength measure. So, when other

type of impact device is used,Set Hardness orσ

b can not be select ( The cursorcould not be moved at Set Hardness or σ

b). If the user used D type impact deviceand set to σb, then exchanged to other type impact device, Set Hardness or σbwill be set as Hardness automatically.

- When the user sets σb to measure, he can not set hardness method ( the cursorcould skip over Hardness Scale).

- Not all hardness methods can be converted to each other for all materials. Thesetting of hardness scale will recover to HL automatically after material setting ischanged. So select material first then select hardness method when setting

measure condition.

- Reset switch is used to cut off the power thoroughly. All settings will be recoveredto ex-work settings after it is turned off. It needs readjustment using standardhardness block when the TH160 is used again. Data in memory will be lost too. Theswitch is sealed by a round piece of paper in 'On' position. Break it first when theswitch must be used.

1. If the preset group number exceeds actual range, print available group.2. To print 1~5 group, you can preset from 1 to 5, or from 5 to 1.3. The bigger the number of the group is, the closer the group to current group number.

Print contents include: tester name, number,operator, time, date, impact device type, impactdirection, average times, material, singlemeasured values and average value.

If the date, impact device type, impact direction,averaging times, material or hardness scale of the

next group are the same as those of the formerone, only the number of unit, single measuredvalues and average value are printed. Otherwise,all content as figure display are printed.
