Comparison of instrument explosion protection standards

Currently, when NEPSI conducts certification, if a complete ATEX/IECEx test report can be provided, they can proceed with the certification process without carrying out tests, and the same applies to FM/CSA

What organization is NEPSI?

Wow, you’re asking about national standards for explosion protection – and you haven’t even heard of NEPSI? NEPSI stands for National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation. It is a technically qualified organization that is authorized to carry out research on fundamental explosion protection technologies, as well as explosion tests, product certification, and inspections and evaluations related to explosion protection in engineering projects. Introduction to 2NEPSI: NEPSI is an international explosion-proof laboratory recognized by the IECEx organization 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 **Grade 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). The NEPSI laboratory was established in 1979 and officially commissioned for operation in 1985. In January 1986, after being approved by the **Ministry of Labor, the explosion-proof testing laboratory was officially named a “**-grade Instrumentation Explosion-Proof Safety Supervision and Inspection Station”.
