under the effect of elastic force, and calculate the hardness value with the ratio of the
rebound speed and impact speed of the punch at a distance of 1mm from the sample
surface. The calculation formula is as follows:
HL=1000 * VB/VA
Where: HL - Leeb hardness value
VB -- Rebound speed of impact body
VA - Impact velocity of impact body

4.5 Preparation before use
Preparation of sample surface
When preparing the sample surface, the influence of heating and cold working on the
sample surface hardness shall be avoided as far as possible.
If the measured surface is too rough, measurement error will be caused. Therefore, the
tested surface must show metallic luster and be flat, smooth and free of oil stain.
Curved surface: The test surface is better to be flat. When the curvature radius R of the
tested surface is less than 30mm (type D, DC, D+15, C, E, DL impact devices) and less
than 50mm (type G impact devices), small support rings or profiled support rings should
be used for testing.
Figure 4 Curved sample face
Support of sample
1. No support is required for heavy samples;
2. For medium-sized samples, they must be placed on a flat and firm plane. The
samples should be placed stably without any shaking;
3. The sample shall have sufficient thickness, and the minimum thickness of the sample
shall comply with Table 3;
4. For the samples with surface hardening layer, the depth of hardening layer shall
comply with Table 3.
Coupling
1. For the light sample, it must be tightly coupled with the solid support, the two
coupling surfaces must be flat and smooth, the amount of coupling agent must not be
too much, and the test direction must be perpendicular to the coupling plane;
2. When the sample is a large area plate, long rod or bending piece, if the weight and
thickness are too large, it may cause distortion and instability of the sample, leading to
