Lighting IK ratings...What does it mean?


In the technical specifications for lighting and light fittings you will often see the "IK rating" - but what does this mean and how does it tell you what is the correct lighting that you need for your application?


Put simply, IK rating indicates the protection against mechanical impact.   IEC/TR 62696:2011(E) covers the testing and classification of luminaires according to IEC 62262.


The application of an IK rating to a luminaire is considered to be a performance issue and is not directly related to the safety provisions of IEC 60598 standards covering luminaire safety.

Application of the IK code as specified on the International Electrotechnical Commission (IEC) Technical Report - Edition 1.0 2011-04.
