What are the differences and connections between the ATEX certification system and IECEx for explosion-proof certifications? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
The ATEX and IECEx standards in Europe are almost identical in content at present.
A key standard is the EN60079 series, another key standard is IEC60079, with ATEX certification, it can be sold in the EU.
Obtaining IECEx certification, theoretically speaking, allows for sales in member countries of the International Electrotechnical Commission (IEC).
If a member state is both in the EU and an international电工, it can apply for ATEX only, without needing an IECEx certification.
Because ATEX falls under the CE category and is a mandatory certification, whereas IECEx is not a mandatory certification.
Additionally, similar situations exist for other IEC member states.
For instance, China is also a member of IEC, but explosion-proof products in China require an application for a Chinese explosion-proof certificate or coal safety certification.
Not to be substituted with IECEx.

Required Documents for ATEX Certification Application at Shenzhen ZhongNuo Testing Technology Co., Ltd.
(1) ATEX Certification Application Form
Samples
(4) Product electrical schematics, assembly drawings, PCB layouts, structural diagrams, component lists and specifications, labels, etc.
(5) Corporate standards and product manuals that meet EN standards requirements
(6) Additional Information

IECEx explosion-proof certification utilizes a certification method that includes type testing (product testing), factory quality system inspection, and post-certification supervision.
So the entire IECEx certification process spans from providing documentation, sample preparation, product testing, factory inspection, to the issuance of the certificate.
