What is the IK protection level test ?

IK refers to the impact protection level of the equipment casing, which usually appears together with the protection requirements of IK and IP. For outdoor electronic equipment, whether it is overhead, buried, or placed outdoors, corresponding IP is required. IK requirements are determined by the joule of the pendulum free fall impact. Specific reference standards include the protection level of the electrical equipment casing against external mechanical collisions.

The purpose of the IK protection level test is to prove that the product casing will not cause damage to the interior of the product in the event of collision. This standard only specifies that the intended use of the casing can meet the requirements of the corresponding product standard in any other aspect. From the perspective of materials and technology, under normal usage conditions, the casing should ensure the indicated protection level. The tests that should be conducted to confirm whether the shell meets the requirements of this standard.

How is the IK level graded ?

IK00 - No Protection
IK01 - Protected against 0.14 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 56mm above the impacted surface)
IK02 - Protected against 0.2 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 80mm above the impacted surface)
IK03 - Protected against 0.35 joules of impact (the equivalent to the impact of a 0.2kg mass dropped from 140mm above the impacted surface)
IK04 - Protected against 0.5 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 200mm above the impacted surface)
IK05 - Protected against 0.7 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 280mm above the impacted surface)
IK06 - Protected against 1 joules of impact (the equivalent to the impact of a 0.25kg mass dropped from 400mm above the impacted surface)
IK07 - Protected against 2 joules of impact (the equivalent to the impact of a 0.5kg mass dropped from 400mm above the impacted surface)
IK08 - Protected against 5 joules of impact (the equivalent to the impact of a 1.7kg mass dropped from 300mm above the impacted surface)
IK09 - Protected against 10 joules of impact (the equivalent to the impact of a 5kg mass dropped from 200mm above the impacted surface)
IK10 - Protected against 20 joules of impact (the equivalent to the impact of a 5kg mass dropped from 400mm above the impacted surface)
