GB/T 19954.2-2016 Electromagnetic compatibility—Product family standard for audio,video,audio-visual and entertainment lighting control apparatus for professional use—Part 2:Immunity
Basic Information
Scope
This part of GB/T 19554 specifies the requirements for electromagnetic immunity testing of equipment, including test signals, performance criteria, and testing methods, covering resistance to conducted and transient electromagnetic interference, including electrostatic discharge. These requirements are essential for electromagnetic compatibility. This part applies to equipment used in the professional audio, video, and audiovisual devices defined in Chapter 3, as well as lighting control equipment for entertainment venues described in Chapter 4, including professional digital devices defined in Section 3.5 and components defined in Section 7.4. The disturbance signal frequency range specified in this part is 0 Hz to 400 GHz, but requirements are not applied to the entire frequency range. Appendix C provides information on infrared emission devices with wavelengths of 0.7 μm to 1.6 μm. This part does not consider the conditions of failure of disturbance sources or interfered equipment. The equipment defined in Sections 3.4, 3.5, and 3.6 can operate under any power supply forms, including: -- public low-voltage grids; -- independent grids with similar characteristics; -- DC power supplies for specific equipment; -- built-in batteries in equipment; -- backup generators. Some standards referenced in this part may not apply to independent low-voltage grids.
