Provides limits for the level of electromagnetic disturbance characteristics produced by lighting equipment and methods of its measurement. This Standard is technically equivalent to and has been reproduced from IEC/CISPR 15:1996. It contains some changes to limits to protect local radio services.

This standard applies to the emission (radiated and conducted) of radiofrequency disturbances from: all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; the lighting part of multi-function equipment where one of the primary functions of this is illumination; independent auxiliaries exclusively for use with lighting equipment; UV and IR radiation equipment; neon advertising signs; street/flood lighting intended for outdoor use; transport lighting (installed in buses and trains).Excluded from the scope of this standard are: lighting equipment for aircraft and airports; apparatus for which the electromagnetic compatibility requirements in the radio-frequency range are explicitly formulated in other IEC or CISPR standards.NOTE Examples are: built-in lighting devices in other equipment, for example scale illumination or neon devices; photocopiers: slide projectors: lighting equipment for road vehicles.The frequency range covered is 9 kHz to 400 GHZ.Multi-function equipment which is subjected simultaneously to different clauses of this standard and/or other standards shall meet the provisions of each clause/standard with the relevant functions in operation.The limits in this standard have been determined on a probabilistic basis to keep the suppression of disturbances within economically reasonable limits while still achieving an adequate level of radio protection and electromagnetic compatibility. In exceptional cases additional provisions may be required.
