IEC62262/60068 IK Impact Hammer Pendulum Tester For Led Lighting Ik Test

IEC62262/60068 IK Pendulum Impact Hammer Test Instrument   IK ratings are defined as IKXX, where “XX” is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against external mechanical impacts. The different IK ratings relate to the ability of an enclosure to resist impact energy levels measured in joules (J). IEC 62262 specifies how the enclosure must be mounted for testing, the atmospheric conditions required, the quantity and distribution of the test impacts and the impact hammer to be used for each level of IK rating.   The European standard EN 62262 - the equivalent of international standard IEC 62262:2002 - relates to IK ratings. This is an international numeric classification for the degrees of protection provided by enclosures for electrical equipment against external mechanical impacts. It provides a means of specifying the capacity of an enclosure to protect its contents from external impacts. The IK Code was originally defined in European Standard BS EN 50102:1995 and amended in 1998. Following its adoption as an international standard (IEC 62262) in 2002, the European standard was renumbered EN 62262.   1.Pendulum:length 1000mm With 0.5kg,1.7kg,5kg hammer
