IK rating refers to the impact protection level of the equipment enclosure, which is mainly used to evaluate the protection ability of the electrical equipment enclosure against external mechanical collision. IK protection level standard is primarily based on IEC 62262 (https://webstore.iec.ch/en/publication/7374).
IK ratings usually appear together with IP ratings. Because for outdoor lamps, the IP and IK requirements are asked together.
The IP rating (Ingress Protection) indicates the level of protection of electrical equipment's housing against foreign object intrusion. (Maybe you are interested in The knowledge of IP Rating for LED lights)
The IK rating is the level of protection against mechanical collisions.
How do we test the IK rating?
The IK protection level is determined by the free-fall impact of an object in joules.
IK protection level tests are generally performed with three test devices: pendulum, spring hammer and vertical drop hammer to achieve the required impact energy.
The specific protection classes range from IK00 to IK10, each representing a different level of impact resistance.
Lighting products, such as LED batten lights, street lights, explosion-proof lights and other special lamps, are required to undergo protection level testing from IK05 to IK10, especially the key levels of IK07, IK08, IK09 and IK10.
IK Rate | Description |
IK00 | No protection. |
IK01 | It withstands an impact force of 0.14J, similar to the impact of a 0.25kg object dropped from a height of 56mm onto the surface. |
IK02 | It withstands an impact force of 0.2J, similar to the impact of a 0.25kg object dropped from a height of 80mm. |
IK03 | It can withstand an impact force of 0.35J, similar to the impact of a 0.25kg object dropped from a height of 140mm onto the surface. |
IK04 | It withstands an impact force of 0.5J, similar to the impact of a 0.25kg object dropped from a height of 200mm on the surface. |
IK05 | It withstands an impact force of 0.7J, similar to the impact of a 0.25kg object dropped from a height of 280mm on the surface. |
IK06 | It withstands an impact force of 1J, similar to the impact of a 0.25kg object dropped from a height of 400mm. |
IK07 | It can withstand an impact force of 2J, similar to the impact of a 0.5kg object dropped from a height of 400mm onto the surface. |
IK08 | It can withstand an impact force of 5J, similar to the impact of a 1.7kg object dropped from a height of 300mm onto the surface. |
IK09 | It can withstand an impact force of 10J, similar to the impact of a 5kg object dropped from a height of 200mm onto the surface. |
IK10 | It can withstand an impact force of 20J, similar to that of a 5kg object dropped from a height of 400mm onto the surface. |
IK Rate | IK00 | IK01 | IK02 | IK03 | IK04 | IK05 | IK06 | IK07 | IK08 | IK09 | IK10 |
Height(mm) | - | 56 | 80 | 140 | 200 | 280 | 400 | 400 | 300 | 200 | 400 |
Weight(kg) | - | 0.25 | 0.25 | 0.25 | 0.25 | 0.25 | 0.25 | 0.5 | 1.7 | 5 | 5 |
Impact energy(J) | - | 0.14 | 0.2 | 0.35 | 0.5 | 0.7 | 1 | 2 | 5 | 10 | 20 |
Conclusion
The IK protection level standard is an important indicator of the protective performance of electrical equipment enclosures. It improves the equipment's safety and reliability. When customizing and using electrical equipment, its IK protection level should be fully considered to ensure its stable operation in complex environments.
