What does the different IK ratings mean?
The resistance of a luminaire against impacts and other external effects can be classified using the international IK rating. The rating uses a scale of IK00–IK10, wherein IK00 does not offer special protection against vandalism. If a luminaire is rated as IK10, it should withstand a direct impact of 20 joules.
- IK01 0,14 J
- IK03 0,35 J
- IK05 0,70 J
- IK06 1 J
- IK07 2 J
- IK08 5 J
- IK09 10 J
- IK10 20 J
Standard EN 60068-2-75 describes the test characteristics for verifying the resistance of a luminaire against external forces. Usually, IK10 (20 joules) is declared as the highest value. It may sound like a high figure, but in practice it corresponds with a 2 kg ball dropped from the height of 1 metre. This test is repeated three times.
The rating of the vandal-proof luminaire by Malux is IK10 or IK10+, meaning that it must withstand impacts of more than 20 joules.
The rating of the vandal-proof luminaire by Malux is IK10 or IK10+
IK rating in practice
The IK10 basic rating is suitable for a broad variety of uses. At the same time, additional protection is required in particularly vulnerable environments. The vandal-proof luminaires by Malux offer extremely good impact resistance, and we have decided to refer to this concept as IK10+.
Enhanced impact resistance. Withstands smaller impacts and dents.
Good impact resistance. Withstands hits and kicks and shots from footballs, floorball etc.
Extremely good impact resistance. Also withstands hits with bludgeons, such as wooden clubs, ice hockey sticks etc. and kicks.
Extremely good impact resistance. Withstands strong hits with a hammer, thrown rocks etc.
