CALIBRATION OF THE IMPACT VELOCITY AT PORTABLE HARDNESS TESTING DEVICES IN ACCORDANCE WITH LEEB

Dieter Schwenk, Maximilian Bandel
Abstract:
MPA NRW realized a new concept for the calibration of the velocity of the impact body of Leeb hardness testers according to the standards DIN 50156, ISO/DIS 16859 and ASTM A 956. A laser vibrometer is used for the continuous measurement of velocity andtime. The measuring device enables the calibration of theimpact velocity of all types of Leeb hardness testers available on the market.
