CCC Ex standards consolidated to GB/T 3836.1

19. May 2022

CNCA has issued 2022 Announcement no.6 on April 26, 2022. According to this announcement, 12 old CCC Ex standards will be consolidated, and in consequence 8 new versions of CCC Ex standards will be implemented from May 1, 2022.

The CCC Implementation Rules for explosion-proof electrical equipment (CNCA-C23-01:2019) will be revised to reflect the change in standards. This revision will not result in any changes to the CCC catalogue. Explosion proof products require a CCC-Ex certification in China.

The consolidated general standard will be GB/T 3836.1. The following 8 new versions of the standards for the different explosion-proof types (d, e, i, p, o, n, m, t) have been updated as part of the consolidation:
