Scope

This Part of GB/T 19554 specifies immunity test requirements, test signals,
performance criteria and test methods for apparatus, involving immunity to continuous
and transient, conducted and radiated electromagnetic disturbances, including
electrostatic discharge, which are the necessary electromagnetic compatibility
requirements.
This Part applies to audio, video, audio-visual and entertainment lighting control
apparatus for professional use as defined in Clause 3 and apparatus used in the
electromagnetic environment described in Clause 4, including the professional digital
apparatus defined in 3.5 and the components specified in 7.4.
This Part specifies that the disturbance signal frequency range is 0 Hz ~ 400 GHz, but
does not make the requirements for the entire frequency band.
Annex C provides relevant information on infrared emitters with wavelengths of 0.7 μm
to 1.6 μm.
This Part does not consider conditions of disturbance source or disturbed apparatus
failure.
The apparatus defined in 3.4, 3.5 and 3.6 may be operated in any form of power supply,
including.
- public low-voltage power grids;
- independent power grids with similar characteristics;
- DC power supplies for specific apparatus;
- built-in batteries of the apparatus;
- standby generators.
Some of the standards referenced in this Part may not apply to independent low-
voltage power grids.
Note 1. In special cases, for example, when portable transmitters are in use near the apparatus,
in addition to the specified limits, additional measurements may be carried out in order to
improve the electromagnetic immunity of the apparatus.
This Part does not apply to.
- consumer electronics products;
- specially designed security system apparatus;
- emission apparatus designed for wireless communications.
