GB 4824-2019 (English Version)

Scope: This standard applies to industrial, scientific and medical electrical (hereinafter referred to as ISM) operating frequencies in the range of 0 Hz to 400 GHz, as well as household and similar appliances designed to generate and/or locally use radio frequency energy. This standard covers the emission requirements of radio frequency disturbance in the 9kHz~400GHz frequency band. However, it is only necessary to perform measurements in frequency bands within the limits specified in Chapter 6. For the industrial, scientific and medical radio frequency applications defined in the International Telecommunication Union (ITU) (see definition 3.13), this standard covers the radio frequency disturbance emission requirements in the 9kHz~18GHz frequency band. Note: The emission requirements of induction cookers are in accordance with the requirements of GB4343.1-2018. This standard also applies to ISM radio frequency lighting equipment and ultraviolet radiation equipment in the ISM frequency band defined by the International Telecommunication Union (ITU) Radio Regulations. This standard does not apply to equipment already covered in other CISPR product categories or other product emission standards.
