Can a domestic NEPSI explosion-proof certification be converted to an international IECEx certification?
Domestic explosion-proof certifications cannot be directly converted to IECEx certifications. This is because the domestic explosion-proof certification standards (GB/T3836) are essentially direct references to the international IECEx explosion-proof certification standards (IEC60079). Therefore, possessing a NEPSI certification does not allow for direct conversion to an IECEx certification.

Explosion-proof electrical products, also known as Ex products, must obtain explosion-proof certification before being allowed for use in hazardous explosive areas.
To eliminate unnecessary repetitive inspections and certifications across international borders for Ex products.
The IECEx Certification System, abbreviated from the guo ji diangong hui Explosion-Proof Electrical Products Certification Organization, was officially established in 1996 to promote international trade.

ATEX explosion-proof certification directives have the following certification modes:
(1) Mode A: Internal Production Control.
(2) B Mode: EC Type Testing. Documentation Review + Product Testing
(3) C Mode: Conforms to type. A quality assurance method, involving annual sampling inspections
(4) D Mode: Explosion-proof system certification. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(5) E-Mode: Product Quality Assurance System. Factory explosion-proof system audit, with annual review, EN ISO-IEC 80079-34-2011 (EN 13980)
(6) F Mode: Product Verification. A method of quality assurance, where each batch of goods is verified prior to export.
(7) G Mode: Unit Certification. Single batch certification for a specific product
