ATEX is the EU's directive for explosive atmospheres, a mandatory certification requirement. The directive code is 2014/34/EU, and the certification standards are the EN60079 series. What is commonly referred to as the防爆CE certification, 2014/EU/34, or EN60079 standard certification actually all refer to the ATEX certification.
Regarding ATEX explosion-proof certification bodies, there are multiple institutions authorized to issue certifications. They are all notified bodies of the EU ATEX directive, holding equivalent certification qualifications. Common certification bodies include TUV, CSA, TI, ECM, etc. During the certification process, these institutions typically adopt the certification method of "product testing + factory audit" (Model B+D or Model B+E).
Of course, customers can also choose an appropriate certification model based on the product's application location.
The certification modes for the ATEX explosion-proof certification directive include the following:
(1) Mode A: Internal Production Control.
(2) B Mode: EC Type Testing. Document Review + Product Testing
(3) C Mode: Type Compliant. A method of quality assurance, with annual sampling inspections conducted on samples.
(4) D Mode: Explosion-proof System Certification. Factory explosion-proof system audit, includes annual review, EN ISO-IEC 80079-34
(5) E-Mode: Quality Assurance System. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34
(6) F Mode: Product Verification. A method of quality assurance, verifying each batch of goods before export.
(7) G Mode: Unit Certification. Single batch certification for a specific product
It's worth noting that while some ECM institutions issue certifications in a straightforward manner, others like TUV, CSA, SGS, and TI typically require product testing and factory inspections for their ATEX certification. An on-site audit of the production facility for certified products is also necessary annually to maintain the certificate's validity. If standards are updated, a certificate renewal is required.
Additionally, while ATEX certification is a European Union explosion-proof certification, it can also be handled as an agency service domestically. Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in ATEX certification agency services, maintains excellent cooperative relationships with international certifying bodies and domestic laboratories, is well-versed in certification standards and procedures, and can provide on-site factory assessment guidance.
