Since October 1, 2019, some explosion-proof electrical equipment has been included in the national mandatory product certification catalog, and everyone is unclear about the relationship between the original production license, explosion-proof qualification certificate, and explosion-proof 3C certification. belowZhongnuo TestingA simple interpretation.
The production license has been cancelled and is no longer available.
Explosion proof certificate refers to the certification certificate for the installation and use of equipment 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 products with explosion-proof certificates. For example, combination equipment, lighting fixtures, non electrical equipment, etc. have not been 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 the scope of products certified with explosion-proof 3C certification?
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 included in the explosion-proof 3C certification standards.
