Those engaged in the explosion-proof industry know that NEPSI certification refers to the explosion-proof certification applied for and processed at NEPSI (National Instrumentation Explosion Safety Supervision and Inspection Station, abbreviated as Shanghai Explosion proof Institute), which is one of the more authoritative explosion-proof certifications in China.

NEPSI can currently issue domestic explosion-proof certificates and IECEx certification certificates.

The abbreviation for the IECEx International Electrotechnical Commission Explosion proof Electrical Product Certification System refers to the certification of electrical equipment specifically used in industrial sectors such as petroleum, chemical, coal mining, textile, grain processing, and military industries where explosive gases, vapors, dust, or fibers may accumulate in hazardous areas.

IECEx certification is an international explosion-proof certification,At present, member countries that belong to the IECEx system directly or indirectly recognize IECEx certification (such as Australia directly recognizing IECEx certification, and China can accept the conversion of IECEx certification to domestic explosion-proof certification).

However, conversely, domestic explosion-proof certification cannot be converted to international IECEx certification. that is becauseChinaExplosion proof certificationThe standard (GB3836/GB12476) basically directly references the international IECEx explosion-proof certification standard (IEC60079). So,Even with NEPSI certification, it cannot be directly converted to IECEx certification.
