IEC60668-2-75 Impact Testing Machine For Vertical Hammer Test With
0-1000mm Drop Height Button Control
Standard:
IEC 60668-2-75-2014 Environmental testing – Part 2-75: Tests – Test
Eh: Hammer tests clause 7 Test Ehc: Vertical hammer.
Application:
It is for testing enclosure mechanical strength of household and
similar electrical appliances, lamps.
Feature:
The device is released by the electromagnet, which can ensure the
instantaneous release and the vertical drop. The lifting device is
combined by screw guide rail, which can make the lower end of the
conduit smooth contact with the surface of the specimen, the fixed
drop height is the length of the guide rail, just contact no need
to adjust, easy to use. Standard equipped with 2, 5, 10, 20, 50 J
hammer and conduit, it is suitable for the enclosure mechanical
strength test of most products.

1. See note in 3.2.2.
2. In this part of IEC 60068, the energy, J, is calculated taking
the standard acceleration due to the earth’s gravity (gn), rounded
up to the nearest whole number, that is 10 m/s² |
