In July 2019, the market issued an implementation notice regarding the transition of explosion-proof electrical products and others from production license 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. Moreover, a transition period of 1 year is provided.
As of October 1, 2020, the above products have not obtained a mandatory product certification certificate and are not marked with the mandatory certification logo.
Not for sale, distribution, import, or use in any commercial 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 implemented in accordance with the rules of the CCC mandatory certification.

Is a product's explosion-proof certification the same as its explosion-proof qualification certificate?
Many customers ask when inquiring, "What is the difference between obtaining a explosion-proof certification and a explosion-proof qualification certificate for a product?"
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 be certified for explosion-proof or obtain an explosion-proof certificate.
The product must pass the explosion-proof standard tests and meet the standard requirements to obtain an explosion-proof certification.
Explosion-proof certification can be categorized according to different protection types, such as intrinsic safety, flameproof, pressurized, and sealed types.
ZhongNuo Inspection has a team of explosion-proof engineers who can provide initial design services for explosion-proof circuits and structures.
Assist companies in preparing the necessary drawings, documentation, and specifications, such as enterprise standards, for explosion-proof certifications, facilitating their easy acquisition of the explosion-proof qualification certificate.
