本标准规定了测量10 kHz至1 GHz频率范围内低压电气和电子设备发出的无线电噪声的统一方法。本标准涵盖了辐射和电力线传导无线电噪声的测量方法，并可适用于任何此类设备，除非个别设备要求另有规定。 这些方法适用于单个组件、单元或包含组件和单元的系统的测量。根据需要，可在本标准中添加其他方法，以满足未来的要求。除非特别指出，本标准不适用于航空电子设备的认证或批准。试验场地（如露天场地和吸收器）的验证方法- 本标准包含30 MHz-1000 MHz频率范围内的内衬腔室。

This standard sets forth uniform methods of measurement of radio noise emitted from low voltage electrical and electronic equipment in the frequency range of 10 kHz to 1 GHz. Methods for the measurement of radiated and power-line conducted radio noise are covered and may be applied to any such equipment unless otherwise specified by individual equipment requirements. These methods apply to the measurement of individual components, units, or systems comprising components and units. Additional methods may be added to this standard to fulfill future requirements as needed. Unless specifically called out, this standard is not intended for certification or approval of avionic equipment. The method for validation of test sites such as open area sites and absorber-lined chambers for frequencies in the range of 30 MHz-1000 MHz is contained in this standard.
