Application cycle for ATEX certification at Shenzhen Zhongnuo Testing Technology Co., Ltd.
The ATEX certification cycle depends on the explosion-proof type, grade, and factory audit conditions agreed upon by the client; the specific duration is subject to the actual situation.

Can an ATEX certificate be used directly in China? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
ATEX certification is applicable to all EU member states but does not serve as a permit for selling explosion-proof products domestically in China.
We have our own explosion-proof certification system. Explosion-proof products sold domestically must pass our explosion-proof certification, not the ATEX certification.
But this does not mean we do not recognize the ATEX certification.
Instead, products that have passed the ATEX certification can enhance their competitiveness.
ATEX certification and explosion-proof certification share many similar standards, such as extensively adopting IECEx certification standards.
If the product has passed the ATEX certification, it is helpful for applying for the domestic explosion-proof certification.
Of course, domestic explosion-proof products typically go through the explosion-proof certification process first before considering export, and ATEX certification is also applied for.

What are the differences and connections between the ATEX certification system and IECEx for explosion-proof certification? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
The ATEX and IECEx standards in Europe are almost identical in content at present.
A primary standard is the EN60079 series, another primary standard is IEC60079
Achieve ATEX certification for sale in the EU, obtain IECEx,
Theoretically, it can be sold in countries that are members of the International Electrotechnical Commission (IEC), such as those that are both members of the EU 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 countries.
China, also a member of the IEC,
However, explosion-proof products require a Chinese explosion-proof certification or coal mine safety certification and cannot be substituted with IECEx.
