Shenzhen Zhongnuo Testing Technology Co., Ltd. is based in South China and specializes in explosion-proof certification and coal safety certification application consulting services, offering one-stop explosion-proof technology consulting services.
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 of Conformity.
The explosion-proof certificate and the explosion-proof 3C certification are for different types of explosion-proof products, and they belong 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 undergo explosion-proof 3C certification, adopting the "Product Testing + Factory Audit" model.
Both product type testing and factory site audit are required.
Ex-proof certificate is applicable to products not listed in the Ex-proof 3C Catalogue. The certification model is Product Testing; upon successful completion of Product Testing, an Ex-proof certificate can be issued.
Of course, products outside the explosion-proof 3C catalog can also apply for an explosion-proof certificate alone, but there's a risk of being penalized by market supervision. This is something the customer needs to consider on their own. When inquiring, customers 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 Inspection & Testing Technology Co., Ltd. for an evaluation and confirmation!

ATEX Certification
ATEX is the European directive for "Equipment and protective systems intended for use in potentially explosive atmospheres."
The aim is to establish a single market within Europe and eliminate trade technical barriers.
Ensure the free circulation of equipment intended for potential explosive hazard environments among its member states.
This directive covers mining and non-mining equipment (including mechanical and electrical equipment).
Expand the potential explosive hazard environment to include airborne dust and flammable gases, flammable vapors, and mist.
Established basic health and safety requirements for the application of equipment intended for potential explosive environments.
And the conformity assessment procedures that must be adopted before the equipment enters the European market.
The current directive is 2014/34/EU.

List of Domestic Explosion-Proof Certification Institutions:
1. Nanyang CNEX
2. Shanghai Coal Research Institute
3. National Electrical Appliance Quality Supervision and Inspection Center
4. Guangdong CQCEx National Explosion-Proof Equipment Quality Supervision and Inspection Center
5. National Coal Mine Explosion-Proof Safety Product Quality Supervision and Inspection Center
6. Jiamusi Explosion-Proof Institute
7. Tianjin PCEC
8. Shanghai NEPSI
9. Beijing Coal Research Institute CCRI, etc.
For applicants, the type of explosion-proof classification and the level of explosion-proof required are actually the same across all authorized institutions. They are all nationally certified and authorized institutions, equipped with testing conditions that meet standard requirements, adhering to the same standards and conducting the same testing. Under the same conditions, it is an inevitable trend to choose institutions that offer more affordable services and prices, which is also a significant reason why emerging explosion-proof companies are gaining popularity.
