Shenzhen ZhongNuo Inspection & Technology Co., Ltd. is headquartered in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering a one-stop explosion-proof technology consulting service.
What explosion-proof certifications are required for explosion-proof products? What consulting agencies are available for explosion-proof certification applications?
Currently, the certification models for explosion-proof products entering the Chinese market mainly consist of three types.
1. Issue explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines. Simply conduct product testing; upon passing, the certificate is issued.
2. Obtain explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory inspection are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, featuring product testing and factory audit certification process.
ZhongNuo Inspection offers explosion-proof certification application consulting services. We provide a one-stop explosion-proof certification and coal safety certification consulting service, including product explosion-proof design, rectification, drawing evaluation, obtaining certificates, and factory audits. We are familiar with certification standards and procedures, have extensive case studies and experience. Feel free to message us!

Does the explosion-proof certification include the explosion-proof 3C certification?
To put it simply, in China, explosion-proof certifications are divided into Explosion-proof 3C Certification and Explosion-proof Compliance Certificate.
As of October 1, 2009, certain explosion-proof electrical equipment was included in the CCC certification catalog, which is a mandatory product certification. Products within the catalog must obtain 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. The explosion-proof 3C certification requires "product testing + factory audit." It's not just about product testing; it also involves an on-site inspection of the production facility. Only after both the product testing and factory audit are passed can the CCC certificate be issued.
A防爆 certification requires product testing, and once the testing is passed, you can frequently issue防爆 certification certificates.
Customers should first confirm the product when inquiring and then determine the certification model.

What test items are included in the explosion-proof certification, 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.
The explosion-proof function is mainly achieved through the protection of the explosion-proof housing.
The explosion-proof housing must have adequate 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 if an explosion occurs in a hazardous area outside, the explosion-proof housing still possesses anti-explosion capabilities.
In summary, the casing is both explosion-proof and anti-explosion. Consequently, the equipment is 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. We offer services including explosion-proof housing design, drafting, certification, and drawing preparation.

Classification of Explosion-proof Certification -- Shenzhen ZhongNuo Inspection & Technology Co., Ltd.
Blastproof certification is the process of verifying that equipment meets the requirements of explosion-proof standards, type testing, and applicable routine tests, and issuing relevant qualification certificates. Certificates can be issued for Ex equipment or Ex components.
Different regions have varying certification standards and systems for explosion-proof electrical products. Currently, international explosion-proof certifications include domestic explosion-proof certification, ATEX certification, IECEx certification, and North American explosion-proof certification, among others.
