Zhongnuo TestingI have been engaged in explosion-proof certification agency services for many years and have encountered various clients. Some clients come to inquire and specify that we need a certificate issued by Nanyang, which has higher authority; Alternatively, our product is a flow meter and requires a certificate issued by Shanghai NEPSI. They are specialized in the field of explosion-proof instruments and meters.....
It cannot be denied that the demands of these clients have a certain degree of reasonableness. For example, as one of the earlier institutions engaged in the field of explosion prevention, Nanyang has established partnerships with domestic institutionsExplosion proof standardThe drafting and revision of many explosion-proof technology experts also have important influence and authority in the field of explosion-proof. But with the development of the explosion-proof product industry, more and more enterprise customers are entering the explosion-proof field, and the demand for certification market is also increasing, which has given rise to another batch of explosion-proof certification institutions.
Due to the fact that explosion-proof products are special products installed and used in special industries in China, the country has strict regulations on market access. yesExplosion proof certification agencyThe authorization is subject to strict and rigorous assessment. Not only for self certified explosion-proof certification institutions such as Nanyang CNEX, Shanghai NEPSI, Tianjin PCEC, but also for emerging explosion-proof certification institutions, it is a qualification assessment. Therefore, for these explosion-proof certification agencies, the authorization qualifications for their explosion-proof business are the same, and they are all authorized by the national CNAS.
At present, in addition to Nanyang CNEX, Tianjin PCEC, and Shanghai NEPSI, there are several other domestic explosion-proof certification agencies (not limited to):
National Explosion proof Equipment Quality Supervision and Inspection Center (Guangzhou Special Inspection Institute)
Shanghai Coal Science Institute
Testing Center of Coal Science Research Institute (Beijing Coal Science Institute)
National Safety Production Changsha Mining Electromechanical Testing and Inspection Center
Chongqing Electric Explosion proof Inspection Station for Coal Industry (Chongqing Coal Science Institute)
National Quality Supervision and Inspection Center for Low Voltage Explosion proof Electrical Appliances (Liaoning)
At present, institutions in China that have the qualifications to issue explosion-proof certificates can be found on the website of the State Administration for Market Regulation.
