IEC60668-2-75 Impact Testing Machine Striking Element Made Of Stainless Steel
Standard:
IEC 60668-2-75-2014 Environmental testing – Part 2-75: Tests – Test Eh: Hammer tests Annex A;
Application:
It is suitable for mechanical impact strength test to electric cabinets and other sheet metal, shell of Non metal electric energy metering cabinet, substation cable switchboard and cable junction box with vertical impact tester or pendulum impact device.
Feature:
The lengths of the striking element are calculated for vertical hammers or for pendulum hammers with arms of negligible mass. When the mass of the arms cannot be neglected, the lengths of the striking element should be reduced so that the equivalent mass meets the requirements of Table 1
Table 1 – Coordinated characteristics of the striking elements
