What explosion-proof certifications are required for explosion-proof products? What are the institutions for applying for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the Chinese market mainly consist of three types.
1. Prepare explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mine shafts.
Just perform product testing, and a certificate will be issued upon passing.
2. Obtain explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory audits are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, involving product testing and factory audit certification.

Are product explosion-proof certification and explosion-proof compliance certificate the same?
Many customers inquire about the difference between obtaining explosion-proof certification for a product and obtaining an explosion-proof qualification certificate.
Explosion-proof certification and explosion-proof compliance certificates are two distinct concepts.
The product has passed the explosion-proof certification, resulting in the issuance of the explosion-proof qualification certificate.
Explosion-proof certification is the process, and the explosion-proof certificate is the result.
So the customer said the product needs to have a explosion-proof certification or explosion-proof compliance certificate.
The product must pass the explosion-proof standard tests and meet the standard requirements to obtain an explosion-proof certification.
Explosion-proof certifications can be categorized into different types of protection, such as intrinsic safety, flameproof, positive pressure, and encapsulation.
ZhongNuo Inspection has a team of explosion-proof engineers who can provide early-stage design for explosion-proof circuits and structures.
Assist enterprises in compiling the drawings, technical specifications, corporate standards, and other documents required for explosion-proof certifications, facilitating their smooth acquisition of the explosion-proof qualification certificate.

Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, domestic explosion-proof certifications include the Explosion-proof 3C Certification and the Explosion-proof Compliance Certificate.
The explosion-proof certificate and explosion-proof 3C certification are for different types of explosion-proof products and fall under different certification models.
As of October 1, 2009, certain explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification.
Products within the catalog undergo explosion-proof 3C certification, adopting a "Product Testing + Factory Audit" model.
Both product type tests and factory on-site assessments are required.
Ex-proof certificate is applicable to products not listed in the Ex-proof 3C Catalogue. The certification model is Product Testing; upon successful completion of Product Testing, an Ex-proof certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for just the explosion-proof certificate, but there is a risk of being penalized by market regulation. This is something the client must consider on their own. When consulting, the client should first confirm what type of product it is, and then decide on the certification model.
If you're still unsure whether the product is listed in the Infringement 3C Catalogue.
