IEC60068-2-75 Adjustable Impact Test Equipment Spring Hammer Test Apparatus For Lab
Adjustable Spring Impact Hammer for IK02 to IK06 Testing According to IEC60068-2-75
1. Introduction:
The spring hammer test apparatus is completed designed according to IEC60068-2-75 figure E.1, the universal spring hammer is adjustable to perform IK01 (0.14J), IK02 (0.2J), IK03 (0.35J), IK04 (0.5J), IK05 (0.7J) and IK06 (1J)tests. IK ratings are defined as IKXX, XX is a number from 00 to 10 which indicates the degrees of protection provided by enclosures against external mechanical impacts. The different IK rating relate to the ability of an enclosure to resist impact energy levels measured in joules (J). It is designed according to IEC60068-2-75 Ehb, and can applicate to IEC60598, IEC60068-2-75 and etc.
