Test item: temperature change (rapid temperature change & thermal shock)
Note:
Rapid temperature change refers to the rapid change of temperature. That is, the temperature change rate of high temperature and low temperature reaches 5-20℃/min and above.
Temperature shock refers to a sharp change in temperature. That is, the conversion time between high temperature and low temperature is 3-5 minutes or ≤ 1 minute.
Temperature change (rapid temperature change)
Temperature change (hot and cold shock)
Test Standard
GB/T 2423.22-2012、IEC 60068-2-14:2009、EN 60068-2-14:2009、GJB 150.5A-2009、MIL-STD-810H、JESD 22-A104E、EIA-364-32D
Test description
Inspect the adaptability of products for storage, transportation, and use in climates with rapid or slow changes in high temperature and low temperature. The test process takes normal temperature→low temperature→low temperature stay→high temperature→high temperature stay→normal temperature as a cycle. The severity of the test conditions is the high (low) temperature range, residence time, temperature change rate (transition time), and the number of cycles. Decide. The temperature change test determines whether the product has physical damage or performance degradation when the surrounding atmospheric temperature changes rapidly. It can provide reliability tests, product screening tests, etc. for products. It is often used to detect materials, electrical, electronics, components and other products.
