Whether Ex components fall within the scope of the explosion-proof CCC certification catalog should strictly comply with the provisions of CNCA-C23-01:2019 "Implementation Rules for Compulsory Product Certification - Explosion proof Electrical" and "Description and Definition Table of Compulsory Product Certification Catalog (Revised in 2020)".

Zhongnuo TestingAccording to the "Implementation Rules for Compulsory Product Certification - Explosion proof Electrical" product catalog, explosion-proof enclosures belong to the mandatory product catalog scope of Class 2313.

Explosion proof enclosure, as a common type of Ex component, also belongs toExplosion proof 3C certificationDo all products in the catalog need to obtain explosion-proof CCC certification?

According to the latest resolution on explosion-proof electrical issued by the State Administration for Market Regulation, whether explosion-proof enclosures, as Ex components, need to obtain explosion-proof CCC certification can be divided into the following situations:

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.
