High and low temperature alternating test chamberProduction testing method:
According to the experimental methods and industry standards, it can be divided into alternating test and constant temperature test. Both test methods are upgraded and expanded on the basis of high and low temperature test chambers. Alternating test chambers refer to instruments that can set the required high and low temperatures, as well as the required temperature time, in one go. The test chamber will follow the set program, which is to set a fixed temperature to make the test effect closer to natural climate, simulate more severe natural climate, and thus increase the reliability of the tested sample.
High and low temperature alternating test chamberThe selection of production environment and reliability testing equipment should follow the reproducibility of environmental conditions:
It is impossible to fully reproduce the environmental conditions that exist in nature in the laboratory. However, within a certain tolerance range, people can accurately and approximately simulate the external environmental conditions that engineering products undergo during use, storage, transportation, and other processes. This statement can be summarized in the language of engineering, which means that "the environmental conditions (including platform environment) created by the testing equipment around the tested product should meet the requirements of the environmental conditions and their tolerances specified in the product testing specifications. The temperature chamber used for military product testing should not only meet the high and low temperature test values and test times specified for different types of products in the national military standards GJB150.3-86 and GJB150.4-86, but also meet the requirements for temperature field uniformity and temperature control accuracy in the test specifications. Only in this way can the reproducibility of environmental conditions be ensured in environmental testing.
