Electromagnetic compatibility - Product family standard for audio, video, audio-visual and entertainment lighting control apparatus for professional use -- Part 1: Emission

This standard for EMC emission requirements applies to professional audio, video, audio-visual and entertainment lighting control apparatus as defined in clause 4 intended for use in the environments described in clause 5. This includes the digital apparatus defined in 4.5 and sub-assemblies, see 7.3. Disturbances in the frequency range 0 Hz to 400 GHz are covered, but requirements are not set over the whole of that range. NOTE 1 : In annex C, information is included on infra-red radiation in the wavelength range 0,7 æm to 1,6 æm. Fault conditions of source or victim apparatus are not taken into account. Apparatus as defined in 4.4, 4.5 and 4.6 may be operated with any source of power. NOTE 2: Sources of power may include, for example: . the public low-voltage supply; . private supplies with similar characteristics; . a d.c. source provided specifically for the apparatus; . batteries internal to the apparatus; . stand by generators. NOTE 3: In special cases, for instance when highly susceptible apparatus is being used in proximity, additional mitigative measures may have to be employed to reduce the electromagnetic emission further, below the specified levels. NOTE 4: Professional user receiving apparatus may be very sensitive to disturbance; see annex D. This standard does not apply to: . consumer apparatus . apparatus specifically designed for security systems . apparatus designed to radiate electromagnetic energy for radio communications purposes.
