1. Self production and self use of explosion-proof shell: No separate CCC certification is required, and the explosion-proof performance of the shell is tested together with the whole machine;

2. The explosion-proof shell production factory designs and manufactures it independently as an Ex component for external sales, and requires obtaining CCC certification;

3. As an outsourcing party, the explosion-proof shell production factory processes according to the design drawings of the whole machine enterprise: no CCC certificate is required, and the explosion-proof performance of the shell is subject to type inspection together with the whole machine; When conducting factory inspections on complete machine enterprises, it can be extended to outsourcing parties for factory inspections. Alternatively, the certification body may conduct an extended review based on the effectiveness of the production enterprise's external quality control.
