Metrology and Calibration Laboratory Metrology and calibration laboratory, founded in 1980s, is an important part of No. 1 Central Station of Metrology of the Machinery Industry. It was authorized as National Pattern Approval Laboratory for Metrological Appliance by AQSIQ in 2015. It mainly undertakes testing and calibration on instruments of electromagnetism, wireless, time frequency, length, climatic (thermo/hygrometer) environment, mechanics, etc. The introduction to EMC Laboratory The Laboratory has one 10m semi anechoic chamber, one 3m semi anechoic chamber and 8 shielded rooms. It is now equipped with advanced automatic electromagnetic interference measuring system, automatic electromagnetic susceptibility testing system, modified semi-anechoic chamber that lined with absorbing ferrite, and shielded enclosures used for performing tests of lectrostatic discharge, pulses, surge, magnetic field, harmonic, conducted emission tests. It is an advanced laboratory of world standard that can performing tests in accordance with update international and national standards (such as IEC, CISPR, EN, FCC, ANSI,ETSI, VCCI, GB standards). Testing fields of nuclear power control equipment, industrial equipment, medical equipment, communications equipment, military equipment, marine equipment, motor vehicle and its parts, providing good technical support and quality assurance for electrical and electronic products from all walks of life. The widest test frequency range at present from 20Hz to 40GHz. The only EMC laboratory which has established and conforms with the nuclear power quality assurance system in China Meeting the third generation nuclear power (AP1000, HPR 1000, etc.) test requirements and one of the few laboratories covered by the civil and military standards (IEC & MIL) in China. A large amount of nuclear tests are performed for various types of industry instruments such as transmitter, sensor, electric actuator, detector, analyzer, DCS sampling system, water treatment system, main control board etc. In 2011, the quality verification of the first equipment for AP 1000 project of Westinghouse Electric Corporation was completed here. Undertaking a number of national key nuclear power projects, carrying out studies on EMC environment of nuclear power plant and is professional with actual requirements and layouts of the plant’ s systems, and owing a valuable data base of electromagnetic interference. Studying on national standards and test methods and preparation of more than 30 national and industry EMC standards, such as GB/T 17626.2, GB/T 17626.3, GB/T 17626.4 and GB/T 17626.9 CCC testing and factory audi A technical team with rich experience and EMC design capabilities to help customers with their product improvement. Capabilities of designing and developing EMC test equipment. Several sets of self-developed equipment have found utilization in more than 60 institutions of the industry. The self-developed GSH series electromagnetic interference testing equipment has won scientific and technological achievements award of the Ministry of Machinery Industry and National Bureau of standards.
