Ik rating for light fitting
2020-01-06

IK level: indicates protection against mechanical shock.

IEC / TR 62696: 2011 (E) covers testing and classification of luminaires according to IEC 62262.

The application of the IK rating to lighting equipment is considered a performance issue and has no direct relationship with the safety regulations of the IEC 60598 standard concerning the safety of lighting equipment.

Application according to the IK code specified in the International Electrotechnical Commission (IEC) Technical Report-Version 1.0 2011-04.

Ratings that demonstrate the degree of Impact Protection (IK) are critical for street, roadway and other lighting products. IP ratings are required per IEC/EN 60598-2-3 for all roadway and street applications. IK ratings are required in specific applications when high impact glass provides protection for the enclosed lamp.
