BAIJIAN - Third party testing organization
The measurement of Leeb hardness tester is based on a relatively simple physical dynamic hardness testing principle. The impact body with a hard metal indenter is pushed towards the surface of the sample through spring force. When the impact body collides with the detection surface、 it will cause deformation of the surface、 which will lead to the loss of kinetic energy. By calculating the energy loss based on the impact and rebound velocities measured at an accurate distance on the surface、 the permanent magnet inside the impact body generates an induced voltage in the single coil of the impact device. The signal voltage is proportional to the velocity of the impact body、 and the signal processed by electronic technology provides hardness readings for display and storage The calculation formula for the Leeb hardness tester is as follows: HL=1000 × Vb/Va、
In the formula: HL - Leeb hardness symbol
Va - impact velocity of the ball head、 m/s
