Enclosure Mechanical impact resistance

Mechanical impact resistance An additional number has sometimes been used to specify the resistance of equipment to mechanical impact. This mechanical impact is identified by the energy needed to qualify a specified resistance level, which is measured in joules (J). This has now been superseded by the separate IK number specified in EN 50102. Although dropped from the 3rd edition of IEC 60529...
