The IK Rating refers to the impact protection level of the equipment case. Usually, we will require both IK rating and IP rating of the equipment. For outdoor electronic equipment, whether it is overhead, buried or ordinary outdoor placement, it needs to have corresponding IP and IK Rated requirements. The IK Rating is determined by the free fall impact of the pendulum in joules. The specific reference standard is the protection level (IK code) of the electrical equipment enclosure against external mechanical impact.

Use of the IK code

Generally to say, the degree of protection applies to the overall housing. If some parts of the case have different IK Rateing, the corresponding protection levels should be marked. If the relevant product committee decides to require the marking of the IK code, the marking requirements shall be specified in detail in the relevant product standard. The product standard should also specify the marking method to be used in the following cases:

1. The protection level of one part of the same case is different from that of other parts;

2. The installation status will affect the protection level of the enclosure.

The IK level is an internationally accepted digital code used to indicate the degree of protection of electrical equipment enclosures against external mechanical impacts. According to IEC 62262:2002 and IEC 60068-2-75:1997 standards, it is the protection ability of electrical equipment enclosures for internal equipment when subjected to external impact.
