IK CODE NF EN 62262
Shock resistance
The European standard EN 62262, the equivalent of the international standard IEC 62262 (2002), concerns IK ratings. This is an international numerical classification of the degrees of protection provided by the enclosures of electrical equipment against external mechanical impacts. It specifies the ability of an enclosure to protect its contents from external impacts. The IK10 classification is the highest vandal resistance rating with an impact energy of 20 joules repeatedly applied to the GRP enclosure.
