In July 2019, the market released an implementation announcement regarding the transition of explosion-proof electrical products and others from production licensing to mandatory product certification.
The announcement clearly 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 aforementioned products have not obtained the mandatory product certification and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any business activities.
This means that in the future, enterprises 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.

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 cause ignition of an explosive gas atmosphere formed by one or more gases or vapors.
Explosion-proof casings must have both explosion-proof and anti-explosion capabilities. Generally, the casings for explosion-proof products tend to be rather bulky.
Products and equipment suitable for fixed installation and use.
Explosion-proof interface 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.
ZhongNuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
We have a dedicated team in the explosion-proof field, well-versed in explosion-proof standard requirements.
We offer explosion-proof housing design, illustration, modification guidance, certification agency services.
