Description:

High and low temperature testing, also known as high and low temperature cycling testing, is a part of product environmental reliability testing. Most products are stored or operated in certain temperature environments. In some environments, the temperature continuously fluctuates, ranging from high to low. For example, in regions with large temperature differences between day and night or when products are repeatedly exposed to high and low temperature zones during transportation, storage, or operation. The high temperature in such environments may exceed 70°C or even higher, while the low temperature may reach -20°C or even lower. These fluctuating temperature environments can affect the product’s functionality, performance, quality, and lifespan, accelerating the aging process and shortening the product’s service life. If the product is exposed to such drastic alternating high and low temperature environments for an extended period, it needs to possess sufficient resistance to high and low temperature cycling. To evaluate the product’s performance in this aspect, it’s necessary to simulate specific environmental conditions and perform high and low temperature testing. If the test results fail to meet the specified standards, the product would need improvement based on the test findings, followed by retesting until it meets the qualifications.

The purpose of this test is to determine the ability of components, equipment, or other products to withstand the usage, transportation, or storage in high temperature environments. It measures the device’s tolerance to extreme high and low temperatures and evaluates the impact of alternating extreme temperatures on the device.

Scope of Application:

Electrical and electronic products such as electronics, components, and circuit boards, etc.
