Introduction


National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (NEPSI) is a specialized establishment that approved and authorized by the government, mainly engaged in research and development of explosion protection technology, testing, verification and certification of electrical equipment for use in explosive atmospheres, as well as explosion protection and safety supervision and assessment of engineering projects.

NEPSI is an international testing laboratory accredited by IECEx Scheme, Shanghai Inspection and Testing Center of Electrical Equipment for use in Explosive Atmospheres for National Work Safety authorized by China State Administration of Work Safety (with qualification of Class A), Explosion-proof Instruments Workstation of Explosion-proof Electrical Equipment Division of National Industrial Product Production Licence Office approved by General Administration of Quality Supervision, Inspection and Quarantine of China(AQSIQ).

The testing laboratory of NEPSIwas initially set up in 1979, and brought into service in 1985. It was in January 1986 that the testing laboratory was officially approved and named by the Ministry of Labor as "National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation".

NEPSI runs strictly in accordance with ISO/IEC17025 and ISO/IEC17020, has achieved a moderately high standard of personnel qualification, management system, testing facilities. As an important part of Shanghai Inspection and Testing Institute of Instruments and Automatic Systems (SITIIAS for short), NEPSI was approved by China National Accreditation Service for Conformity Assessment (CNAS) for its inspection and testing ability. Among its technical staff, most are engineers or senior engineers with more than ten years of experience. Some of them were trained, visited or did cooperative research work in famous international organizations, such as SIRA, Factory Mutual Research Cooperation (FMRC), Physikalisch-Technische Bundesanstalt (PTB), Bergbau-Versuchsstrecke of DMT Company (DMT/BVS), Technischer Uberwachungs-Verein, Hannover (TUV Hannover), Laboratoire Central des Industries Electriques (LCIE), TIIS, TESTSAFE/SIMTARS, KTL/KOSHA, BKI and LOM. Some of them are members of Chinese National Standardization Committee for Explosion-protected Electrical Equipment, Chinese Society of Labor Protection, Shanghai Special Committee for Fire and Explosion Protection, Committee of Electrical Equipment for Hazardous Locations of Instrument Society of America (ISA SP12), IECEx International Certification Scheme, international assessor of IECEx Scheme.

Supported by government departments concerned, NEPSI gets progressive increase in testing and inspection competence, businesses, and international exchange and co-operation, and enjoys good reputation both at home and abroad.

NEPSI, authorized by the government, is mainly engaged in research and development of explosion protection technology, testing and verification of electrical equipment for hazardous locations, as well as safety supervision for users of such equipment and safety assessment of engineering projects in accordance with the instructions of the government departments.

Main tasks of NEPSI:

   Popularizing and carrying out safety-related policies, laws and regulations of the state;

    Testing, verification and certification of electrical equipment for hazardous locations;

    Inspection and factory audit for IECEx, ATEX and CQM certification;

    Safety assessment of electrical equipment in operation in hazardous areas;

             Undertaking state key research projects concerning fundamental explosion protection technology;

             Research and development of testing technology on explosion protection;

             Working at standardization at home and abroad;

             Preparation of technical standards of explosion-protected instruments;

             International communication on industrial explosion protection and safety technology;

             Explosion protection and safety evaluation for enterprise safety production permit for production, transportation, store up and use of hazardous chemicals.

 

Abilities and achievements:

Testing abilities: General requirements of explosion protection; Ex d; Ex e; Ex I; Ex p; Ex o; Ex q; Ex n; Ex m; DIP, tD, iD, mD, pD; heat tracing cable; combustible gas detector, etc.

The lab has totally issued nearly 1, 5000 explosion protection certificates by 2008, among which  5000 were issued to about 600 manufacturers from USA, Germany, UK, Japan, Canada, Netherlands, Italy, Korea, Switzerland, New Zealand, Finland, etc.

NEPSI has made considerable efforts to promote international exchange and cooperation , and has hosted numbers of international forums and exhibitions on explosion protection technology, which have greatly promoted China’s testing and certification technology of explosion protection and safety to be in line with international practice.

    Since the lab signed a mutual recognition agreement with FM (US) in 1991, it has established bilateral cooperative relations of mutual recognition with more than ten well-known institutions such as PTB, TUV Nord, EXAM, DEKRA, UL, DNV, LCIE/BV, INERIS, TIIS, TestSafe, KTL, KOSHA, KGS, LOM, Sira, Baseefa, CCVE, BKI and so on.

NEPSI has completed a great lot of basic scientific research on explosion protection among which three were granted respectively the first, second and third grade “Scientific and Technological Progress Awards” by the Ministry of Machinery Industry. Besides, one of the studies won third grade “National Safety in Production Scientific Research  Achievement Prize”.

 

NEPSI is willing to provide excellent service with top-ranking skill.
