General inspection standards for high and low temperature impact test chambers

High and low temperature impact test chamber: It is suitable for high temperature and low temperature reliability test of industrial products. For the parts and materials of related products such as electric and electronic, automobile and motorcycle, aerospace, shipbuilding, colleges and universities, research institutes, and other high-temperature and low-temperature (alternating) cyclical changes, test their performance indicators. The product has a wide temperature control range, and its performance indicators have reached the technical requirements of the national standard GB10592-89 high and low temperature impact test chamber, and are applicable to the environmental test A: low temperature test method according to GB2423.1 and GB2423.2. Test B: High Temperature Test Method" The product was subjected to low temperature, high temperature test and constant temperature test. Products meet GB2423.1, GB2423.2, GJB150.3, GJB150.4, IEC, MIL standards.

GB/T5170.2 standard specifies the test items of temperature (including low temperature, high temperature and temperature change) test equipment, main instruments and requirements for inspection, inspection load, inspection conditions, inspection methods, data processing results and inspection results, inspection cycle, etc. content. The test equipment applicable to this standard is tested by high temperature test chamber, low temperature test chamber and high and low temperature test machine. GB/T5170.2 standard specifies the inspection items for high and low temperature testing machines, the contents are as follows: 1, temperature deviation; 2, temperature fluctuation; 3, temperature uniformity; 4, wind speed; 5, temperature change rate; 5min temperature average change rate; 7, temperature recovery time; 8, temperature indication error; 9, temperature overshoot; 10, temperature overshoot recovery time; 11, noise. GB/T5170.2-2008 Electrical and electronic products, environmental testing equipment, testing methods, temperature testing equipment
