1、 Introduction to High and Low Temperature Testing: High and low temperature testing, also known as high and low temperature cycling testing, is a part of environmental reliability testing. Basically, all products are stored and stored in a certain temperature environment, or run in operation. In some environments, the temperature will constantly change, from high to low. This constantly changing temperature environment can affect the functionality, performance, quality, and lifespan of products, accelerate their aging, and shorten their lifespan. If the product is exposed to such high and low temperature environments with significant alternating changes for a long time, it needs to have sufficient resistance to high and low temperature cycling. In this way, we need to simulate certain environmental conditions and conduct high and low temperature tests on the product. High and low temperature testing is the abbreviation of high temperature test and low temperature test, and the purpose of the test is to evaluate the impact of high and low temperature conditions on the performance of equipment during storage and operation. High temperature testing: It is used to determine the adaptability of products to storage, transportation, and use in high-temperature climatic conditions. The severity of the experiment depends on the high temperature and exposure duration. Low temperature testing: It is used to determine the adaptability of products to storage, transportation, and use in low-temperature climatic conditions. The severity of the experiment depends on the low temperature and exposure duration. Reliability testing project climate environment - high and low temperature testing, constant humidity and heat, alternating high and low temperature humidity and heat, salt spray testing, gas corrosion, UV aging, temperature shock, rapid temperature change, temperature and humidity, etc. Mechanical environment - Drop, pressure, simulated sports car II. High and low temperature inspection standards. High temperature testing inspection standards: GB/T 2423.2, IEC 60068-2-2, IEIA 364, MIL-STD-810F low temperature testing inspection standards: GB/T 2423.1, IEC 60068-2-1, EIA 364, MIL-STD-810F temperature range: -70 ℃~150 ℃, temperature difference: ± 0.5 ℃, humidity range: 20~98% RH, humidity difference: ± 2.5% RH
