On March 12, 2024, the MIIT solicited opinions on the revised mandatory national standard "Single phase plugs and socket-outlets for household and similar purposes—Types, basic parameters and dimensions (draft for comments)", with the deadline set for May 10, 2024.

This standard specifies the types, basic parameters, dimensions, and test methods for single-phase plugs and socket-outlets for household and similar purposes. It is applicable to single-phase plugs and socket-outlets used in household and similar environments, with an alternating current frequency of 50 Hz and a rated voltage of 250 V, and a rated current not exceeding 32 A.

Compared to the previous version of the standard (GB/T 1002—2021), the main technical changes include:

l  Addition of explanations and diagrams for socket-outlet slot combinations.

l  Changes in the thickness tolerance of plug pins and corresponding gauge tolerances.

l  Addition of dimensions for 32A plug and socket-outlet types, as well as parameters for the distance of live plug pins from the edge, the height of insulation sleeves for 32A plugs, and the minimum distance of live plug sleeves from the mating surface.

Single-phase plugs and socket-outlets for household and similar purposes are products listed in the Chinese Compulsory Product Certification (CCC) catalog. The new standard will be crucial for obtaining CCC certification for relevant products to enter the Chinese market. Overseas companies should actively provide feedback on this standard to minimize future compliance risks and costs.
