Impact resistance

Important: We assume no liability for cited standards!
The IK classification is an international standard which describes suitability for the widest range of ambient conditions. It states how resistant articles such as enclosures are to mechanical stress. The official classification with IK codes of 00 to 10 specifies impact resistance up to a defined minimum level of impact energy which the enclosure must withstand. This code is expressed by means of the letters IK and a two-digit code number.
