What is the ik grade standard?

IK grade refers to the equipment shell anti-impact protection level, usually IK and IP protection requirements are present together, for outdoor electronic equipment, whether it is overhead, buried or ordinary outdoor placement, need to have the corresponding IP, IK requirements, IK level is the joule unit of the swing hammer free fall impact to determine, the specific reference standard, electrical equipment shell on the external mechanical collision of the protection level (IK code).

Ik codes are typically used, and the protection rating is applied to the overall enclosure. Product standards should also specify the marking method used in the following cases:

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

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

IK rating is an internationally accepted digital code used to represent the protection rating of electrical equipment housings against external mechanical collisions. According to IEC 62262:2002 and IEC 60068-2-75:1997, the protective capability of the electrical equipment housing in the event of an external force collision on the internal equipment.

IK00 – No protection.

IK01 – To withstand a 0.14J impact force (the equivalent of 0.25KG weight of an object falling from a height of 56mm onto the surface)

IK02 – To withstand a 0.2J impact force (equivalent to 0.25KG of objects falling from 80mm high on to the surface)

IK03 – To withstand a 0.35J impact force (the equivalent of 0.2KG weight of an object falling from a height of 140mm to the surface of the impact)

IK04 – To withstand a 0.5J impact force (equivalent to an object weighing 0.25KG falling from a height of 200mm to the surface)

IK05 – To withstand a 0.7J impact force (the equivalent of 0.25KG weight of an object falling from a height of 280mm to the surface of the impact)

IK06 – 1J impact force (equivalent to 0.25KG weight of object falling from 400mm high on the surface impact)

IK07 – 2J impact force (equivalent to 0.5KG weight of object falling from a height of 400mm on the surface impact)

IK08 – 5J impact force (equivalent to 1.7KG of objectfalling from 300mm to the surface impact)

IK09 – 10J impact force (equivalent to 5KG of objects falling from 200mm high on the surface impact)

IK10 – 20J impact force (equivalent to 5KG weight of object falling from a height of 400mm on the surface impact)
