Inner Mongolia local metrology calibration specifications calibration specifications for air thermal aging test chamber passed the examination and approval. On August 31, Inner Mongolia Bureau of Quality Supervision held a newly formulated examination and approval meeting for local metrology calibration specifications in Inner Mongolia Autonomous Region at Xing'an League Institute of quality and metrology. The meeting reviewed and approved the calibration specification for air thermal aging test chamber, a local measurement calibration specification drafted under the auspices of Xingan League Institute of quality and measurement. Zhangyongcheng, director of the Metrology Department of the Quality Supervision Bureau of the autonomous region, and tianbihai, deputy investigator, attended the meeting. The meeting was presided over by director zhangyongcheng. In this review meeting, famous experts from the temperature professional technical committee were invited to form an expert group to review this local measurement calibration specification

calibration specification for air thermal aging test chamber was jointly prepared and drafted by the calibration specification preparation team established by Xing'an League Institute of quality and Metrology in conjunction with the Metrology Institute of the autonomous region, Hulunbuir Institute of quality and Metrology and Inner Mongolia deta Technology Co., Ltd. The team members have collected a large number of relevant data about the existing air thermal aging test chamber in China. On the basis of the theoretical research conducted by the Ministry of Commerce of the people's Republic of China and the Ministry of science and technology of the people's Republic of China, and the test verification of repeatedly improving their own advantages, they refer to the advanced standards and measurement methods at home and abroad, in order to calibrate the air thermal aging test chamber with the most economical and reasonable standard instruments and methods. After widely soliciting the opinions of users of air thermal aging test chamber and a number of measurement technical institutions, it has been revised and improved, and a draft for review has been formed

the expert group carefully reviewed the newly formulated calibration specifications, preparation instructions, uncertainty evaluation report of measurement results and test report. Approved, Experts believe that: after detecting the angular displacement signal and sending it to the accounting machine for data processing, it is good to directly unload the newly formulated Inner Mongolia (I don't know whether your technical data are complete, the method is scientific and reasonable, the measurement unit is used correctly, and the compilation format is in line with the JJF Compilation Rules for national measurement calibration specifications It is required that the final examination and approval results are passed and can be submitted to the Quality Supervision Bureau of the autonomous region for approval

the air thermal aging test chamber is a test equipment that uses air as the medium and controls the temperature and air exchange rate. It is mainly used for the heat resistance test of electrical insulation materials, the air exchange aging performance test of electronic parts, plastic products and rubber products. After the samples are aged in the air under simulated high temperature and atmospheric pressure, their performance is measured and compared with the performance of the non aged samples

product quality is related to safety in production and people's property and life, especially the occurrence of "Xi'an wire and cable quality incident". People pay more attention to the detection of the aging degree of wires and cables. Whether the measuring performance of air thermal aging test chamber is accurate and reliable directly affects the quality of relevant products. It is very important to formulate a scientific and reasonable calibration specification for the accuracy and effectiveness of product test results, On the basis of a large amount of research, Xingan League Institute of quality indicators has formulated the calibration specification for air thermal aging test chamber, which fills the gap of this calibration specification in the autonomous region, and is also the first successful practice of drafting local measurement calibration specifications by League and municipal measurement verification institutions
