From October 16^th to 17^th, 2021, the China National Accreditation Service for Conformity Assessment (CNAS) appointed Mr. WANG Dong, Mr. CUI Yu and Ms. LOU Yafen to form an expert group to conduct on-site evaluation of the National Center for Materials Service Safety (NCMS) operated by USTB. Mr. ZHANG Weidong, Vice President of USTB and General Director of NCMS; Ms. XIA Xiuqin, Secretary at the Party Committee of NCMS; Ms. JIN Ying and Mr. LU Yonghao, Associate Directors of NCMS; and all personnel of CNAS quality system of NCMS attended the on-site evaluation.

Mr. ZHANG Weidong welcomed the three evaluation experts on behalf of USTB and NCMS, and Ms. JIN Ying briefly introduced the construction and operation of CNAS quality system of NCMS to the evaluation experts.

Subsequently, three experts carried out the on-site laboratory evaluation of all elements including the 6 testing stations/rooms and all the technical capabilities applied by the NCMS according to the CNAS-CL01:2018 Accreditation of Testing and Calibration Laboratories and other criteria. The expert team meticulously inspected the conformity, suitability and effectiveness of the NCMS quality management system through on-site testing, use of proficiency testing results, verification of instrument and equipment configurations and other methods.

At the final meeting of the on-site evaluation on October 17^th, Mr. WANG Dong, on behalf of the expert group, read out the evaluation results to NCMS: the NCMS quality management system is operating effectively, the management attaches great importance to the continuous improvement of the quality management system, and various factors affecting the quality activities are in a good state of control. As a result, the NCMS passed the on-site evaluation. At the same time, the expert group also suggested the NCMS to complete the rectification in accordance with the provisions and combined with the nonconformities found in the on-site evaluation.

Mr. ZHANG Weidong expressed his gratitude for the work of the evaluation team and requested all personnel in the CNAS quality system of the NCMS to seriously comply with the requirements of the expert group, strictly abide by the rules and procedural requirements of the system, learn by analogy, and make timely and effective rectification of the expert group’s evaluation opinions. Further, promote the overall management of the CNAS quality system in the NCMS laboratories, bring more qualified laboratories into the system for management, effectively improve the laboratory management level of the NCMS, and lay a solid foundation for the completion of the construction goals of NCMS.

On August 16^th, 2019, the CNAS testing laboratory quality system was officially approved by NCMS and put into formal operation. Six testing stations and testing rooms, including Atmospheric Corrosion Environment Test Facility, High Temperature and High Pressure Environment Testing Facility have been established. It is equipped with more than 81 sets of testing equipment such as Subcritical Water Environment Corrosion Testing Machine and Autoclave with Rotating Cylinder Electrode Testing Machine, etc. The testing capability covers 20 items in three major testing fields: mechanical properties testing, corrosion testing and organizational structure testing of metal materials and products.
