Since October 1, 2019, when some explosion-proof electrical equipment was included in the national mandatory product certification catalog, people have been confused about the relationship between the original production license, explosion-proof qualification certificate, and explosion-proof 3C certification. belowZhongnuo TestingGive a brief interpretation. The production license has been cancelled and no longer exists. Explosion proof certificate is a certification certificate for equipment installed and used in places with explosive gases and dust. Explosion proof 3C certification is aimed at explosion-proof electrical equipment included in the national mandatory product certification catalog. The scope of equipment here is much smaller than that of explosion-proof certification products. For example, modular equipment, lighting fixtures, non electrical equipment, etc. are not includedExplosion proof 3C certificationcatalogue The product catalog for explosion-proof 3C certification can refer to other articles by the editor. So, sinceExplosion proof certificateIs the execution standard for product certification the same as that for explosion-proof 3C certification, as their product scope is different? In terms of explosion-proof electrical equipment, it is completely the same. Non electrical equipment and combination equipment are not included in the explosion-proof 3C certification catalog, therefore, these two standards are also not part of the explosion-proof 3C certification standards.
