Explosion-proof product certification typically refers to the safety certification required for explosion-proof products to enter the market, commonly known as explosion-proof certification, and the certificate issued is called the Explosion-Proof Compliance Certificate.
CCC Certification, which stands for "China Compulsory Certification," is also known as "China Compulsory Certification."
Abbreviated as CCC. The CCC certification mark is "CCC," which is recognized and supervised by the Certification and Supervision Commission according to the "Administrative Regulations for Compulsory Product Certification."
Regulation No. 5 of the Chinese Quality Supervision, Inspection and Quarantine on product certification system.

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion-proof design for electrical equipment.
The housing is capable of withstanding explosive mixtures entering the housing through the housing joint surfaces or structural gaps, without damage upon internal explosion.
And ignite an explosive gas environment formed by one, multiple gases or vapors from the outside.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the outer casings of products designed for explosion-proof purposes are rather bulky.
Products and equipment suitable for fixed installation and use.
Explosion-proof junction face width, gap, and roughness are the three key elements of explosion-proof housing design.
Design requirements for explosion-proof three elements vary depending on the different explosive gas environments used in Class I mining, non-mining Class IIA, IIB, and IIC.
Refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.

Does a product need to undergo explosion-proof design before applying for the 3C explosion-proof certification?
That's for sure.
The product undergoes explosion-proof 3C certification, which involves passing the relevant test items of the explosion-proof standards and the process of applying for the explosion-proof 3C certificate.
To ensure the product passes the explosion-proof standard test items, it is necessary to design the product according to the test requirements, which is to implement explosion-proof design.
For explosion-proof requirements, refer to GB/T3836.1 and GB/T3836.2.
The design must refer to GB/T3836.1 and GB/T3836.4 for intrinsic safety.
The design of positive pressure should refer to GB/T3836.1 and GB/T3836.5.
