values after the measurement has been performed.

2.4 Leeb Hardness Testing Principle

The basic principle shortly described:

An impact body with a certain weight impacts against the

testing surface under certain test force. Then the impact

velocity and the rebound velocity of the impact body are

measured respectively while the spherically test tip is

located 1 mm above the testing surface.

The calculation formula is as follows:

HL= 1000 x VB/VA

Where HL= Leeb Hardness Value

VB= Rebounding velocity of the impact body

VA= Impact velocity of the impact body

3. Preparation

3.1 HMP Preparation and Inspection

The instrument is calibrated by using the test block,

included in delivery. The error and repeatability of the

displayed value should be within the regulation of

APPENDIX Table 2.

The instrument and the impact device have to be

calibrated using a standard hardness block before the first

use. If the hardness tester has not been used for a longer

period, it is also recommended to calibrate it and as well, if

the instrument’s system has been reset.

To power on the instrument, the key has to be pressed

and held, meanwhile the key is also pressed. Then the

calibration screen is shown as on page 4.

5 points have to be tested on the standard hardness block.

After that, the average value of those 5 measured values

will be displayed. The keys and have to be

pressed to change its nominal value.

Finally the calibration has to be confirmed by pressing the

key. To cancel the calibration, the key has to be

pressed. Range of adjustment: ±30 HL

The measurement parameters, including the material

setting, the hardness scale and the impact direction, can’t

be changed during calibration.

3.2 Impact Device Selection

For the selection of impact devices, please refer to

APPENDIX Table 1 and Table 3.

3.3 Preparation of the Sample Surface

Preparation of the sample surface should conform to the

relative requirements in APPENDIX Table 3.

 During the preparation of the sample surface,

any heating or cold processing on this surface

should be avoided.

 Too big roughness of the surface being

measured could cause errors. The surface of the

sample should show metallic luster, be smooth

and polished, without any stains of oil etc.

 Support of the sample is not necessary for

heavy objects. Medium-weight samples have to

be placed onto a smooth and stable plane. It

must be placed in absolute equability and

without any wobble.

 Curved surface: The best testing surface, of

course, is flat. When the curvature radius R of

the surface to be tested is smaller than 30 mm

(D, DC, D+15, C, E and DL type of impact

device) and smaller than 50 mm (G type of

impact device), the small support rings should

be chosen.

 The sample should have enough thickness, the

minimum thickness of it should conform to

Table 3.

*For a sample with a hardened layer on its surface,

the depth of the hardened layer should also conform

to Table 3.

 Coupling: Light-weight samples must be firmly

coupled with a heavy base plate. Both coupled

surfaces have to be flat and smooth; there may

not rest any redundant coupling agent. The

impact direction must be vertical to the coupled

surface. If the sample is a big plate, long rod or

bending piece, it can be deformed and become

unstable, even though its weight and thickness

is big enough; accordingly, the test value might

not be accurate. So the sample should be

reinforced or supported at its back.

 Magnetism of the sample itself should be

avoided.

4. Testing Program

4.1 Start-up

 The plug of the impact device has to be inserted

into the socket of the impact device of the

instrument.

 The key has to be pressed to power on. Now

the instrument is in working mode.

4.2 Testing

- The release button on the upside of the impact device

has to be pressed to start testing. The sample and the

impact device as well as the operator are all required to be

stable now. The action direction should pass the axis of

the impact device.

- Each measurement area of the sample usually needs 3

to 5 times of testing operations. The result data dispersion

should not be more than the mean value ± 15 HL.

- The distance between any two impact points or from the

centre of any impact point to the edge of the sample

should conform to the regulation of Table 4-1.

- If an accurate conversion from the Leeb hardness value

to another hardness value is requested, a contrastive test

is needed to get conversion relations for the special

material. An inspected qualified Leeb hardness tester and

a corresponding hardness tester have to be used to test at

the same sample respectively. For each hardness value,

each homogeneous measurement, 5 points of Leeb

hardness value are needed. They are in the surroundings

of more than three indentations which need conversion of

hardness. The Leeb hardness arithmetic average value

and the corresponding hardness average value as

correlative value respectively are used to establish an

individual hardness contrastive curve. The contrastive

curve at least should include three groups of correlative

data.

4.3 Read Measured Value

After each impact operation, the current measured value

will be displayed, to the impact times always one is added.

The buzzer alerts with a long howl if the measured value is

not within the valid range. If the presetted impact times are

reached, the buzzer alerts with a long howl. After two

seconds it will alert a short howl and the mean measured

value will be displayed.

4.4 Notes

* Replacement of the impact device must be done during

the instrument is powered off. Otherwise the main body

cannot identify the type of the impact device. This might

damage the circuit board of the main body.

* The current test value cannot be saved if the impact

times are less than the presetted times value.

* Only D and DC type of impact device have got the

function of strength test option. It isn’t possible to change

the setting to strength tests by using other types of impact

device. The setting will be automatically set to hardness

testing after replacing the impact device; no matter the

setting is hardness testing or not before.

* Not all materials can be converted to all hardness scale

values. The hardness scale is reset to HL automatically

after changing material. So, material has to be selected

first before changing the hardness scale.
