2.5 Leeb Hardness Testing Princip e
The basic principle is: use an impact body of certain eight impacts against the testing
surface under certain test force, then measure the impacting velocity and the rebounding
velocity of the impact body respectively hen the spherically test tip is located 1mm
above the testing surface.
The calculation formula is as follo s:
HL=1000×VB/ VA
Where, HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
3 Preparation & Testing
3.1 Preparation & Inspection before Testing
3.1.1Preparation of Samp e Surface
Preparation for sample surface should conform to the relative requirement in the Table 3.
(1) In the preparation processing for sample surface, the hardness effect of being heated
or cold processing on the surface of sample should be avoided.

(2)Too big roughness of the being measured surface could cause measure error. So the
surface of the sample to be measured must appear metallic luster, smoothing and polish,
ithout oil stain.
(3)Support of test sample. Support is no necessary for heavy sample. Medium eight
parts must be set on the smoothing and stable plane. The sample must set absolutely
equability and ithout any obble.
(4)The sample should have enough thickness, and minimum thickness of sample should
conform to Table 3.
(5)For the sample ith hardened layer on surface, the depth of hardened layer should
conform to Table 3.
(6)Curved surface: The best testing surface of sample is flat. When the curvature
radius R of the surface to be tested is smaller than 30mm (D, DC, D+15,C, E and DL type
of impact device) and smaller than 50mm (G type of impact device), the small support
ring or the shaped support rings should be chosen.
(7) Coupling. Light- eight sample must be firmly coupled ith a heavy base plate. Both
coupled surface must be flat and smooth, and there is no redundant coupling agent
existing. The impact direction must be vertical to the coupled surface. When the sample
is a big plate, long rod or bending piece, it can be deformed and become unstable, even

though its eight and thickness is big enough, and accordingly, the test value may not
be accurate. So the sample should be reinforced or supported at its back.
(8)Magnetism of the sample itself should be avoided.
Table 3
3.1.2 System Setting
See 4.5 for details.
3.1.3 Presetting Testing condition
See 4.2 for details.
3.2 Testing Program
Verification of the tester is by using standard test block. The error and repeatability
of displayed value should be ithin the regulation of table 4.
Note：Use a calibrated hardness tester, test the standard test block
downward vertically for 5 times, the arithmetical average value compare with
the value of standard test block. If this value exceeds the standard value,
could use the function of software calibration to adjusting.

3.2.1 Start-Up
(1)Insert the plug of the impact device into the socket of impact device on the tester.
(2)Press key，no po er is connected. The instrument is in testing condition.
Table 4:
3.2.2 Loading
Pushing the loading-tube do n ards until contact is felt. Then allo it to slo ly
return to the starting position or using other method locking the impact body.
Chart 1 Chart 2 Chart 3
3.2.3 Loca ization
Press the impact device supporting ring on the surface of the sample firmly, and the
impact direction should be vertical to the testing surface.
3.2.4 Testing
(1)Press the release button on the upside of the impact device to test. The sample and
the impact device as ell as the operator are all required to be stable no .

The action direction should pass the axis of the impact device.
(2)Each measure area of the sample usually need 5 times of testing operation. The result
data dispersion should not more than mean value±15HL.
(3)The distance bet een any t o impact points or from the center of any impact point to
the edge of testing sample should conform to the regulation of Table 5.
Table 5
(4)If you ant accurate conversion from the Leeb hardness value to other hardness
value, contrastive test is needed to get conversion relations for the special material. Use
inspection qualified Leeb hardness tester and corresponding hardness tester to test at
the same sample respectively. For each hardness value, each measure homogeneously 5
points of Leeb hardness value in the surrounding of more than three indentations hich
need conversion hardness, using Leeb hardness arithmetic average value and
corresponding hardness average value as correlative value respectively, make individual
hardness contrastive curve. Contrastive curve at least should include three group of
correlative data.

The system ould automatically detect the type of the impact device during po er
up and ould display this information on the screen as belo .
Follo ing is the main display interface as belo .
4.2 Test Set
Pressat the main interface to enter the main menu—Leeb H Tester, as belo . Press

keyorcould continuously glance do n ard or up ard.
Press to enter menu “Set parameter”. Press key or to move the cursor to the line
you ant to set, and press keyto enter submenu.
4.2.1 Hard/σ setting
Press keyor to move the cursor to the line of “Measure H”，and then press key to
s itch H/TS continuously.
Note：
1. H is short for Hardness and TS is short for strength.
2. When H/TS is switched to TS, the hardness scale could not be selected.
3. Only D type of impact device has the function of TS measure. So the impact device could
not be selected.
4.2.2 Impact Direction Setting
Press keyor to move the cursor to the line of “Set DIR” ，and press key to enter

submenu ”Set DIR ” , and then press keyor to choose one of the five kinds of impact
