The high and low temperature test, also known as the high and low temperature cycle test, is a part of environmental reliability testing. It mainly simulates the high and low temperature changes in the natural environment to test the heat resistance, cold resistance, and dry resistance of the product. Generally, it includes high temperature test, low temperature test, and temperature and humidity change test.
In certain environments, temperatures can sometimes be high and sometimes low. This constantly changing temperature environment can affect the functionality, performance, quality, and service life of products, accelerate product aging, and shorten their service life. If the product is exposed to such alternating high and low temperature environments for a long time, it needs to have sufficient ability to resist high and low temperature cycles.
one
What industry products are suitable for high and low temperature testing?
This test is applicable to fields such as electronics and electrical engineering, automotive and motorcycle industry, aerospace, rubber and plastics, metals and materials, shipbuilding industry, universities, research institutions, etc.
two
High and low temperature test requirements in GB/T 2423 standard
GB/T 2423.1-2008 Low temperature test
Experimental purpose: To assess the adaptability of test samples to storage or use under low temperature conditions. Commonly used for type testing of products during the development phase, screening testing of components, etc.
Test equipment: High and low temperature test chamber or constant temperature and humidity test chamber.
Test conditions: Generally, a constant temperature and test time are selected.
Temperature requirements: -65 ℃, -55 ℃, -50 ℃,
-40 ℃, -33 ℃, -25 ℃, -20 ℃, -10 ℃,
-5 ℃,+5 ℃, etc;
Duration: 2h, 16h, 72h, 96h
GB/T 2423.2-2008 High temperature test
Experimental purpose: To assess the adaptability of test samples to storage or use under high temperature conditions. Applied to instruments, equipment, etc. working in high-temperature environments such as tropical weather or steel mills.
Test equipment: High and low temperature test chamber or constant temperature and humidity test chamber.
Test conditions: Generally, a constant temperature stress and holding time are selected.

Duration: 2h, 16h, 72h, 96h, 168h, 240h, 336h, 1000h
three
What are the standards for high and low temperature testing?
GB/T 2423.2-2008 Environmental Testing for Electrical and Electronic Products Part 2: Test Methods Test B: High Temperature
GB/T 2423.1-2008 Environmental Testing for Electrical and Electronic Products Part 2: Test Methods Test A: Low Temperature
IEC 60068-2-2:2007 Basic environmental testing procedures Part 2-2: Test B: Dry heat
IEC 60068-2-1:2007 Environmental testing for electrical and electronic products: Low temperature
four
What are the general requirements for determining high and low temperature tests?
1. The product surface has no defects such as damage or deformation. If the surface is coated, there should be no peeling, bubbling, or discoloration of the coating.
2. For plastic parts, there are no cracks, bubbles, or deformations on the surface.
3. Rubber products have no signs of aging, bonding, softening, or cracking.
4. There is no flow phenomenon in the welding parts of the product parts.
5. The product performance data and structural functions meet the technical requirements and should not have any other defects that hinder the normal operation of the product.
