IK07 2J Spring Hammer
1. Introduction
2J spring hammer is for IK07 impact test. IK ratings are defined as IKXX, XX is a number from 00 to 10 which indicated 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's designed according to IEC60068-2-75 and can applicate to IEC60598 etc. IK07 spring hammer is for 2J impact energy levels.
