The relationship between explosion protection certification and NEPSI certification

Thread Content

Having been involved in explosion-proof certification for many years, clients often ask about NEPSI certification, CNEX certification, PCEC certification, and so on. These are all the abbreviations for the major domestic explosion-proof certification bodies. NEPSI is an **explosion-proof safety supervision and inspection station for instruments and equipment, namely the Shanghai Explosion-Proof Electrical Testing and Inspection Center. It is an internationally recognized explosion-proof laboratory accredited by the IECEx system of the International Electrotechnical Commission ； It is the Shanghai Explosion-Proof Electrical Equipment Testing and Inspection Center for work safety, **authorized by the State Administration of Work Safety** (with **Class A qualification for work safety testing and inspection**) ； It is the Explosion-Proof Instrument Workstation of the Explosion-Proof Electrical Equipment Review Department, part of the National Industrial Product Production License Office, which was established with the approval of the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ). https://p3-tt.byteimg.com/origin/pgc-image/0b3794a6a89e40dea622b19fcaf2795f?from=pc CNEX is an abbreviation for “**explosion-proof”, and it is a registered trademark of Nanyang Explosion-Proof Electrical Research Institute. It is also the abbreviation for Nanyang Explosion-Proof Institute. PCEC is a **compulsory product certification body and laboratory designated by the Certification and Accreditation Administration. **The Explosion-Proof Product Quality Supervision and Inspection Center (Tianjin)/Petroleum and Chemical Industry Electrical Product Explosion-Proof Quality Supervision and Inspection Center is a testing and inspection institution that provides services such as inspection and testing of equipment for special environments, certification, and training and consulting. The NEPSI certification, CNEX certification, and PCEC certification that we often mention are actually the explosion-proof certifications issued by these several explosion-proof certification bodies, which conduct the tests and issue the certificates. In addition, there are other domestic explosion-proof certification agencies in China, such as the Shenchuan Institute, Guangzhou Special Inspection Institute, Suzhou Electric Power Research Institute, Jiamusi Institute, Beijing Coal Research Institute, etc., which are also qualified to issue explosion-proof certification certificates. Clearly, the NEPSI certification is just one of the certification bodies for explosion-proof certification.
