National Commercial Refrigeration Equipment Quality Inspection and Testing Center (formerly known as National Commercial Refrigeration Equipment Quality Supervision and Inspection Center) and Huashang International Engineering Co., Ltd. Refrigeration and Food Processing Equipment Testing Laboratory are authorized by the state (CAL/CMA) and international mutual recognition (CNAS) The third-party testing laboratory of China, the registration number is: CNAS L3069. It was originally an inspection agency under the Ministry of Commerce and was founded in 1978. In 1994, for the first time, it was accredited and authorized by the national quality inspection agency organized by the former State Bureau of Quality and Technical Supervision. The laboratory covers an area of ??905 m2, of which the test site is 683 m2. Equipped with more than 150 sets of main testing instruments, worth over 10 million. The central laboratory has many postdoctoral fellows, doctors, masters, etc., one professor-level senior engineer title, and enjoys special national allowances, and many senior engineer titles have formed a team with complete professional, reasonable structure, solid foundation and strength Strong scientific research team. Strictly abide by the provisions of CNAS-CL01: 2018 "Testing and Calibration Laboratory Competency Accreditation Guidelines", RB/T214-2017 "General Requirements for Inspection and Testing Institutions Qualification Accreditation Capability Evaluation Inspection and Testing Institutions" and related application instructions, establish and center workload, An independent, fair, scientific and honest management system suitable for the type of work and scope of work. Responsible for the long-term work of the two secretariats of the National Refrigeration Standardization Technical Committee Refrigerator Sub-Technical Committee and the National Refrigeration Standardization Technical Committee Terminology and Definition Sub-Technical Committee, organized and directly participated in the formulation and revision of more than 20 national and industry standards and the testing of standard technical indicators It has been verified that it has a leading position in the domestic cold chain industry. The existing testing business covers the whole cold chain and has more than 50 testing capabilities recognized by CNAS. The detection range includes ski resorts, ice skating rinks, cold storage, containers, pre-coolers, freezers, air coolers, condensers and ice machines, etc. Check the operating status, etc. The center provides objective test results to the entrusting party in the form of "inspection report", and can also provide qualification certificates or appraisal results according to the entrusting party’s requirements and relevant regulations. The test report issued by the center is authoritative and fair, has legal effect, and can be used for legal arbitration. As the new generation force of the center, the R&D department has strong scientific research capabilities, and can independently research and develop testing equipment, refrigeration equipment and new testing technology, and provide enterprises with the design, installation, commissioning and other services of testing laboratories and testing equipment and facilities. The center led the design and installation of more than 10 laboratories, completed 3 provincial and ministerial-level new technology research and development projects, completed 4 related research and development products for cold storage refrigeration systems, and won a number of industry science and technology innovation awards.
