GB 17799.3-2023 Electromagnetic compatibility (EMC) — Generic standards — Part 3: Emission standard for equipment in residential environments
1 Scope
This document is generic EMC emission standard and is applicable only if no relevant dedicated product or product family EMC emission standard has been published.
This document for emission requirements applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. It also applies to electrical and electronic equipment intended for use at other locations that do not fall within the scope of IEC 61000-6-8 or IEC 61000-6-4.
The intention of this document is that all equipment used in the residential, commercial and light-industrial environments are covered by this document or IEC 61000-6-8. If there is any doubt the requirements in this document apply.
This document specifies the conducted and radiated emission requirements in the frequency range up to 400 GHz, with the aim to provide an adequate level of protection of radio reception in the defined electromagnetic environment. Not all disturbance phenomena have been included for testing purposes but only those considered relevant for the equipment intended to operate within the locations included within this document.
The emission requirements in this document are not intended to be applicable to the intentional transmissions and their harmonics from a radio transmitter as defined by the ITU.
Note 1: Safety considerations are not covered by this document.
Note 2: In special cases, situations will arise where the levels specified in this document will not offer adequate protection; for example where a sensitive receiver is used in close proximity to an equipment. In these instances, special mitigation measures can be employed.
Note 3: Disturbances generated in fault conditions of equipment are not covered by this document.
Note 4: As the requirements in this document are more stringent or equivalent to those requirements in IEC 61000-6-4 and IEC 61000-6-8, equipment fulfilling the requirements of this document comply with the requirements of IEC 61000-6-4 and IEC 61000-6-8.
