GB 17799.4-2022
ActiveElectromagnetic compatibility (EMC)—Generic standards—Part 4: Emission for industrial environments
电磁兼容 通用标准 第4部分：工业环境中的发射
Application Summary AI generated
This standard specifies emission limits for electrical and electronic equipment intended for use in industrial environments, including areas supplied from high-voltage or low-voltage industrial networks. It is applied to ensure that equipment does not generate electromagnetic disturbances exceeding acceptable levels, covering a frequency range from 0 Hz to 400 GHz. The standard is used for compliance testing of industrial machinery, control systems, and power equipment to meet EMC regulatory requirements in factory, manufacturing, and heavy industrial settings.
