GB 4824-2019 Industrial,scientific and medical equipment—Radio-frequency disturbance characteristics—Limits and methods of measurement
Abstract
This standard applies to industrial, scientific, and medical electrical equipment (hereinafter referred to as ISM) with operating frequencies in the range of 0 Hz to 400 GHz, as well as household and similar appliances designed for generating and/or locally using radio frequency energy.
This standard covers the emission requirements for radio frequency interference in the frequency range of 9 kHz to 400 GHz. However, measurements only need to be conducted in the frequency bands specified by the limits in Chapter 6.
For ISM radio frequency applications defined by the International Telecommunication Union (ITU) (see Definition 3.13), this standard covers the emission requirements for radio frequency interference in the frequency range of 9 kHz to 18 GHz.
Note: The emission requirements for induction cookers are in accordance with the requirements of GB 4343.1—2018.
This standard also applies to ISM radio frequency lighting equipment and ultraviolet irradiation equipment within the ISM frequency bands defined by the ITU Radio Regulations.
This standard does not apply to equipment already covered by other CISPR product categories or other product emission standards.
