Ensure samples and technical drawings meet explosion-proof standards prior to inspection.
Avoided the hassle and extra costs of repeated modifications and testing.

The explosion-proof certificate is a certification model for products outside the explosion-proof 3C catalog.
As of October 1, 2009, a portion of explosion-proof electrical equipment was included in the CCC certification list, which is a mandatory product certification. Products on the list require an explosion-proof 3C certification, following the "product testing + factory audit" model. For a detailed explosion-proof 3C certification list, please refer to the relevant information on our website. Explosion-proof products not on the list can opt for obtaining an explosion-proof qualification certificate; certification is granted upon passing the product testing.
The general process for obtaining an explosion-proof certificate includes: submitting product-related documents, conducting product testing, and upon passing the test, issuing the explosion-proof certificate. Throughout the application process, ensure that your product meets the relevant explosion-proof standards and requirements.
If you're not familiar with explosion-proof standards and certification requirements, no worries. Shenzhen ZhongNuo Testing Technology Co., Ltd. can provide explosion-proof design and modification, certification agency services for intrinsic safety, flameproof, encapsulation, and positive pressure types, facilitating your company's convenient handling of explosion-proof certificates.

Does the explosion-proof certification include the explosion-proof 3C certification?
Currently, in China, explosion-proof certifications are categorized into Explosion-proof 3C Certification and Explosion-proof Certificate Certification.
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products, belonging to different certification models.
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 listed in the catalog are subject to explosion-proof 3C certification, following the "Product Testing + Factory Audit" model.
Both product type testing and on-site factory audits are required.
Certification of explosion-proof compliance is applicable to products not listed in the explosion-proof 3C catalog. The certification model involves product testing; upon successful testing, an explosion-proof certification can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for explosion-proof certificates, but there's a risk of being penalized by market regulation. This is something for the client to consider on their own. When inquiring, the client should first confirm the type of product and then decide on the certification model. If you're unsure whether your product is within the explosion-proof 3C catalog, you can private message Shenzhen ZhongNuo Testing Technology Co., Ltd. for an assessment and confirmation!

Division of explosion-proof areas in explosive gas environments
Explosive gas environments and combustible dust environments are classified based on the different physical states of substances present in the location for explosion-proof certification. These environments with different physical states are further divided into three zones according to the duration of the presence of hazardous substances in the location.
That is: for explosive gas environments, Zones 0, 1, and 2.
Areas with continuous or long-term presence of explosive gas environments, generally above 1000 hours per year.
Zone 1 - Areas where explosive gas environments may occur during normal operation, typically 10-1000h/year
Zone 2 - Under normal operating conditions, explosive gas atmospheres are unlikely to occur or, if they do, are temporary and of short duration, generally less than 10 hours per year.
