IEC60668-2-75 Calibration Device For Spring Hammers Impact Testing Machine
Standard:
IEC 60668-2-75-2014 Environmental testing – Part 2-75: Tests – Test Eh: Hammer tests Annex B;
Application:
This device is intended to verify the impact energy of spring operated impact hammers.
Test sample:
Spring hammer test apparatus
Principle of calibration:
The principle of this calibration procedure is to compare the energy provided by a spring hammer, which is difficult to measure directly, to the energy of a pendulum, calculated from its mass and height of fall.
