IK Rating or “Impact Protection” (the K is from 'Kinetic' to differentiate from IP rating) is defined in international standards and indicates the level of resistance an electrical enclosure provides against mechanical impact. IK ratings are an important factor when choosing LED lighting which may be fitted in an area that could be subject to rough environment, attempted vandalism or other impacts.
The numbers that follow the IK have a specific meaning and indicate the level of protection from mechanical impact. It is a 1 to 10 system with a higher number indicating a more robust product able to maintain safety at higher energy impacts.
By applying the required amount of energy (joules) to the enclosure. We do these standard tests in a controlled environment by 'control dropping' set weights from set heights and angles onto the enclosure. To apply the correct amount of impact energy (joules) we use the specified method in the standard to deliver the energy. Strikes without bouncing are performed three times on the same spot. This test is performed at several locations on each test enclosure, looking for weaknesses, to ensure IK rating is valid for the whole product, not just the tougher bits.
