Temperature change test

The temperature change test is mainly aimed at the adaptability test of electrical, electronic products, their original components, and other materials when they are stored, transported, and used in environments with rapid temperature changes. The severity of the test depends on high/low temperature, residence time, and number of cycles.
There are two types of temperature change tests in practical applications: one is a slow temperature change test, with a temperature change rate <3°C/min; the other is a rapid temperature change test, with a temperature change rate ≥3°C/min. The faster the temperature change rate, the more stringent the assessment.
