We are well-versed in the application process and technical requirements for explosion-proof 3C certification, and can provide clients with consulting services such as application assistance and factory audit guidance.
Do you have a product catalog for explosion-proof electrical equipment that has been converted to a mandatory product certification (CCC certification)?
ZhongNuo Inspection: Yes. The market is transitioning from production licenses for explosion-proof electrical equipment to mandatory product certification.
We also issued a notice regarding the transition of explosion-proof electrical products from production license to mandatory certification scope.
Products within the product catalog must be produced, sold, or engaged in other business activities during the transition period with a valid production license or CCC certification.
After the transition period, only products with valid CCC certification can be manufactured, sold, or otherwise engaged in business activities.

Products with a composite explosion-proof type that have obtained the explosion-proof certification are not listed in the explosion-proof CCC catalog, but the components inside are. How should this be handled?
ZhongNuo Inspection: If components are self-manufactured, a CCC certificate must be applied for. If purchased externally, components with a CCC certificate are required.

What are the requirements for companies applying for the mandatory product certification (CCC certification) after converting explosion-proof electrical products?
ZhongNuo Inspection: Mandatory Product Certification, also known as CCC Certification, the certification model includes type testing + initial factory inspection + post-certification supervision. In simpler terms, it requires a factory audit. Applicant companies must have the capability for production/inspection/shipment (or OEM/ODM).

How do I apply for an explosion-proof certificate? Which organizations issue explosion-proof certificates?
The explosion-proof certificate is a certification that ensures the safety of equipment used in explosive environments.
The certification standards are the GB/T 3836 series. The process for a company to apply for an explosion-proof qualification certificate is quite simple.
Please provide the product's electrical schematic, assembly drawing, structure diagram, product manual, and corporate standards, etc.
And provide samples that are consistent with the drawings for explosion-proof testing. Upon passing the test,
You can then issue the Explosion-Proof Testing Report and the Explosion-Proof Compliance Certificate.
Currently, the main explosion-proof certification issuing bodies include Nanyang CNEX, Tianjin PCEC, Shanghai NEPSI, various Coal Research Institutes, Suzhou Electric Science Institute, and others.
These institutions all have comprehensive Certificates, with the validity of the certificates being identical.
Although the process is relatively simple, it's not easy to meet the design requirements of the GB/T 3836 series standards for the product.
