GB/T 9254.2-2021 Information technology equipment,multimedia equipment and receivers—Electromagnetic compatibility—Part 2:Immunity requirements

Scope

This document applies to information technology equipment (3.1.18), audio equipment (3.1.6), video equipment (3.1.32) , broadcast receiving equipment (3.1.7), entertainment lighting control equipment (3.1.14) and their combinations with a rated AC voltage effective value or DC voltage not exceeding 600 V.
This document also applies to the above-mentioned equipment for professional use.
Equipment with broadcast receiving functions is within the scope of this document, see Appendix A. Equipment with non-broadcast wireless interfaces is also within the scope of this document, however, there is no need to evaluate the performance of these interfaces according to this document.
Equipment for which immunity requirements are specified in the frequency range by other IEC/CISPR standards corresponding national standards (except GB/T 9383 and GB/T 17618) is not included in the scope of this document.
The purpose of this document is:
——To propose requirements within the frequency range of 0 Hz~400 GHz, so that the EUT has sufficient immunity levels and can operate as expected in the environment in which it is used.
——To specify procedures to ensure the reproducibility of the test and the repeatability of the results.
Due to the technical integration of equipment functions, the performance criteria are determined based on functions rather than on equipment.
