Does the explosion-proof certification include the explosion-proof 3C certification?
In this regard, in China, explosion-proof certifications are divided into Explosion-Proof 3C Certification and Explosion-Proof Certificate of Conformity.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification. Products within the catalog must apply for the explosion-proof 3C certification, while explosion-proof products outside the catalog require the explosion-proof qualification certificate certification.
This falls under different certification models. For the explosion-proof 3C certification, it involves both "product testing and factory audit." It's not just about product testing; a physical audit of the manufacturing facility is required as well. Only after the product testing and factory audit are both passed can the CCC certificate be issued.
Explosion-proof certification requires product testing. Upon passing the testing, the explosion-proof certificate can be issued frequently.
Customers should first confirm the product during the inquiry and then the certification model to be pursued.

What test items are included in the explosion-proof certificate, and what are the requirements?
Explosion-proof is one of the most commonly used explosion-proof types for explosion-proof products on the market, adhering to the standards GB/T 3836.1 and GB/T 3836.2.
Primarily, explosion-proof is achieved through the protection of a隔爆外壳.
The explosion-proof housing must have sufficient thickness and strength; even if an explosion occurs inside the equipment, the flame will be extinguished due to the width, gap, and roughness of the housing's joint surfaces, preventing ignition of the external hazardous environment.
On the other hand, even in the event of an explosion in a hazardous area outside, the explosion-proof housing retains its anti-explosion properties.
In summary, the shell is both explosion-proof and shockproof. Consequently, the equipment will be rather heavy.
ZhongNuo Inspection has been deeply involved in the explosion-proof field for many years, well-versed in the requirements of the GB/T 3836 series standards.
We have extensive experience in the design and modification guidance for explosion-proof products, offering services such as explosion-proof housing design, drafting, certification, and drawing preparation.

How to check the explosion-proof certification
Buyers and selectors of explosion-proof electrical equipment always choose manufacturers or distributors with explosion-proof certification.
How do consumers verify the authenticity and validity of explosion-proof certificates?
Currently, there are over a dozen certified issuing bodies in China for domestic explosion-proof certificates.
There is no unified platform for querying explosion-proof certification issued by various authorities.
Explosion-proof certificates issued by various institutions can only be verified on their respective websites.
Certainly, each issuing agency can verify the authenticity of certificates by phone.
If the query certificate is genuine, the main parameters and validity period will be displayed below.
If so, of course, it wouldn't be found.
It's worth noting that due to the manual uploading of certification documents by various issuing authorities, there is a certain lag.
That is to say, the newly acquired certificate may not necessarily be searchable on their website.
It's time to consult with the shipping agency directly.
