Congratulations! Envsafe Obtained CNAS Laboratory Accreditation
Suzhou Envsafe Testing Co., Ltd (hereinafter referred to as “Suzhou Envsafe”) obtained the official laboratory accreditation certificate issued by the China National Accreditation Service for Conformity Assessment (CNAS) on August 31, 2022.
This indicates that Suzhou Envsafe detection technology and management level have been recognized by the state, and it has reached the national first-class level in the explosive detection of combustible substances. At the same time, this means the data and reports Suzhou Envsafe issued are authoritative and credible, and are recognized by international mutual recognition.
The full name of CNAS is China National Accreditation Service for Conformity Assessment. It is an accreditation body approved and established by the Chinese Certification and Accreditation Administration (abbreviated as CNCA) in accordance with the "Regulations of the People's Republic of China on Certification and Accreditation". It is the most authoritative laboratory certification management organization in China.
China's national accreditation system for conformity assessment plays an important role in international accreditation activities. Its accreditation activities have been integrated into the international accreditation and mutual recognition system and have an important position in the international A full member of Laboratory Accreditation Cooperation (ILAC), Asia Pacific Laboratory Accreditation Cooperation (APLAC) and Pacific Accreditation Cooperation (PAC), it has signed mutual recognition agreements with 54 laboratory accreditation bodies in other countries and regions.
Suzhou Envsafe Testing Co., Ltd is a wholly owned subsidiary of VILLO & Envsafe Environmental Protection and Safety Research Institute (Suzhou) Co., Ltd.
As one of the rare CNAS-accredited laboratories in the domestic powder explosion characteristics testing industry, Suzhou Envsafe has a detection area of nearly 500 square meters, 7 sets of core testing instruments and a large number of auxiliary equipment, including 20L Spherical explosion test system, Minimum ignition energy test system for dust cloud, Minimum ignition temperature test system for dust layer, Minimum ignition temperature test system for dust cloud, Dust specific resistance test system, Accumulated dust self-ignition characteristic test system, Laser particle size distribution analyzer and Electronic balance, etc.
Suzhou Envsafe has strictly followed the requirements of the CNAS system since its establishment. From the setting of the organizational structure, to the allocation of laboratory resources, the grasp of the requirements of the testing process and the operation of the management system, it has built a system document that complies with ISO17025.
