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.
Achieve ATEX certification for sale in the EU, obtain IECEx,
Theoretically, it can be sold in member states of the International Electrotechnical Commission (IEC), such as a country that is both a member of the European Union and the IEC, where an IECEx certification may not be required.
Apply for ATEX only, as it is a mandatory certification under the CE category.
IECEx is not a mandatory certification. Moreover, similar situations exist for other IEC member states.
For instance: China, also a member of the IEC.
However, explosion-proof products require a Chinese explosion-proof certificate or coal safety certification, and cannot be substituted with IECEx.
