On December 28, 2023, the Standardization Administration of China (SAC) issued SAC Standard Announcement No. 21 to publish twenty-three national mandatory standards. Two of them are regarding Electro Magnetic Compatibility (EMC) and are all identical adoption from IEC standards. Further details of the two standards are summarized below.

GB 17799.3-2023 Electromagnetic compatibility (EMC)—Generic standards—Part 3: Emission standard for equipment in residential environments

This standard is an identical adoption from IEC 61000-6-3:2020 Electromagnetic compatibility (EMC) - Part 6-3: Generic standards - Emission standard for equipment in residential environments.

This standard is applicable only if no relevant dedicated product or product family EMC emission standard has been published. It applies to electrical and electronic equipment intended for use at residential (see 3.1.14) locations. This part of IEC 61000 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 is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt the requirements in IEC 61000-6-3 apply. The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected 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.

GB 17799.8-2023 Electromagnetic compatibility (EMC)—Generic standards—Part 8: Emission standard for professional equipment in commercial and light-industrial locations

This standard is an identical adoption from IEC 61000-6-8:2020 Electromagnetic compatibility (EMC) - Part 6-8: Generic standards - Emission standard for professional equipment in commercial and light-industrial locations.

It is applicable only if no relevant dedicated product or product family EMC emission standard has been published.

This standard applies to electrical and electronic equipment intended for use in commercial and light-industrial (see 3.1.3) locations. This document applies to equipment that satisfy the following restrictions of use:

• is defined as professional equipment (see 3.1.13),

• is professionally installed and maintained (see 3.1.14 and Clause 6),

• is not intended to be used in residential locations (see 3.1.16).

IEC 61000-6-3 applies to electrical and electronic equipment intended for use at commercial and light-industrial locations that do not satisfy these restrictions.

The intention is that all equipment used in the residential, commercial and light-industrial environments are covered by IEC 61000-6-3 or IEC 61000-6-8. If there is any doubt, the requirements in IEC 61000-6-3 apply.

Emission requirements within the frequency range 0 Hz to 400 GHz are covered.

The conducted and radiated emission requirements in the frequency range up to 400 GHz are considered essential and have been selected 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.

To summarize, both standards will come into force on July 1, 2024. Although mandatory standards mean compulsory implementation force, but being identical adoption from IEC standards will not cause much impact for MNCs and stakeholders who has already comply with the international ones.
