1 Scope
This European Standard for EMC emission requirements applies to professional audio,
video, audio-visual and entertainment lighting control apparatus as defined in 3.6 intended
for use in the environments described in Clause 4. This includes the digital apparatus defined in 3.5 and sub-assemblies, see 6.3.
Disturbances in the frequency range 0 Hz to 400 GHz are covered, but requirements
are not set over the whole of that range. See Note 5.
NOTE 1 In Annex D, information is included on infra-red radiation in the wavelength range 0,7 µm to
1,6 µm.
Fault conditions of source or victim apparatus are not taken into account. Apparatus
as defined in 3.4, 3.5 and 3.6 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. Some standards
may not apply to private low-voltage supplies.
NOTE 3 In special cases, for instance when highly susceptible apparatus is being used in
proximity, additional mitigation 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 E.
This European Standard does not apply to
-
- consumer apparatus,
-
- apparatus specifically designed for security systems, and
-
- apparatus designed to radiate electromagnetic energy for radio communications purposes.
NOTE 5 To ensure freedom from interference, manufacturers should consider the characteristics
of other equipment likely to be in the same environment and thus determine whether
limitation of emissions in additional frequency ranges is necessary.
The objective of this standard is to define limits and methods of measurement for
apparatus defined in the scope, in relation to continuous and transient, conducted
and radiated disturbances. These requirements represent essential electromagnetic compatibility requirements.
