According to the latest resolution on explosion-proof electrical equipment issued by the State Administration for Market Regulation, is it necessary to apply for explosion-proof CCC certification for explosion-proof enclosures as Ex components? There are several situations:

1. Explosion proof shell for self-produced and self used use: No separate CCC certification is required, and the explosion-proof performance of the shell is subjected to type testing along with the entire machine;

2. Explosion proof shell manufacturers design and manufacture their own products as Ex components for external sales: CCC certification is required;

3. As an outsourcing party, the explosion-proof shell production factory processes according to the design drawings of the entire machine enterprise: no CCC certificate is required, and the explosion-proof performance of the shell is subjected to type inspection along with the entire machine; When conducting factory inspections on whole machine enterprises, it can be extended to outsourced parties for factory inspections. Alternatively, certification bodies may conduct extended evaluations based on the effectiveness of quality control by external partners of the production enterprise.
