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.
Its housing can withstand explosive mixtures entering the housing through the housing joint surfaces or structural gaps, and explode internally without causing damage.
And cause ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the outer casings of products designed for explosion-proofing tend to be rather bulky.
Products and equipment suitable for fixed installation and use.
Explosion-proof face width, gap, and roughness: 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.

We generally refer to explosion-proof product certification as the safety certification for explosion-proof products entering the market, commonly known as explosion-proof certification, with the certificate being called an explosion-proof qualification 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 Administration according to the "Regulations for Compulsory Product Certification."
Regulation No. 5 of the China Quality Supervision, Inspection and Quarantine Commission for product certification system.
In July 2019, the market issued an implementation notice regarding the conversion of explosion-proof electrical products and others from production licenses to mandatory product certifications.
The announcement explicitly states that as of October 1, 2019, explosion-proof electrical equipment, household gas appliances, and household refrigerators with a rated capacity of over 500L will be included in the CCC certification management scope. Additionally, a transition period of one year is provided.
As of October 1, 2020, the above products have not obtained a mandatory product certification and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any business activity.
This means that in the future, companies applying for explosion-proof certification will be required to undergo the CCC mandatory certification, and will be executed in accordance with the implementation rules of the CCC mandatory certification.
