Can IECEx certification be converted to a domestic explosion-proof certification? -- Shenzhen ZhongNuo Testing Technology Co., Ltd.
Currently, the IECEx certification is driven by standards, which is a voluntary certification.
But the IECEx certification enjoys a high recognition in the international market.
Most IECEx member states directly or indirectly recognize IECEx certification.
If the product has obtained IECEx certification,
Provide a valid Report (Ex Report issued by an Ex Certification Body (Ex CB) from other member states within the IECEx system and a Factory Quality Condition Report (QAR)).
Manufacturers from other member states holding an IEC Ex certificate need only conduct a portion of the testing to apply for access to regional certification pathways.
For example, China, as an IEC member, still requires a Chinese explosion-proof certificate or coal safety certification for explosion-proof products.
This cannot be substituted with IECEx. In summary, if a country is a member of the IEC but also has its own mandatory explosion-proof certification,
It is typically mandatory to apply for your own explosion-proof certification, rather than simply substitute it with an IECEx explosion-proof certification.
Of course, at times, the already obtained IECEx Report (possibly with additional testing items) can be utilized.
To convert into a domestic mandatory explosion-proof certification, it is essential to undergo confirmation and review by the application authority.

Can ATEX certificates be used directly in China? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
ATEX certification is applicable to all EU member states, but it does not serve as a permit for selling explosion-proof products domestically in China.
Domestic products have their own explosion-proof certification system. Explosion-proof products sold domestically must pass the Chinese explosion-proof certification, not the ATEX certification.
However, this does not imply a lack of recognition for the ATEX certification; on the contrary, obtaining ATEX certification can enhance the competitiveness of the product.
ATEX certification and ATEX Zone 1 certification share many similar standards in their references.
For example, most have converted to the IECEx certification standards. If the product has passed the ATEX certification,
It helps with applying for domestic explosion-proof certification.
Certainly, domestic explosion-proof products usually apply for the Chinese explosion-proof certification first, then consider exporting, and apply for ATEX certification.

What are the differences and connections between the ATEX certification system,防爆认证, and IECEx? -- Shenzhen Zhongnuo Testing Technology Co., Ltd.
Currently, the ATEX and IECEx standards in Europe are almost identical.
A key standard is the EN60079 series, another is IEC60079, with ATEX certification, it can be sold in the EU.
Obtaining IECEx certification, theoretically, 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 IECEx.
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, also a member of IEC, but explosion-proof products in China require an application for the Chinese explosion-proof certification or coal safety certification.
And cannot be replaced with IECEx.
