The thermal cycling test with specified rate of change is used to safeguard components and products against sensitivity to changing ambient temperatures. As a rule, the temperature changes to be expected in the product life cycle (e.g. day/night, summer/winter) are simulated. The thermomechanical stress to be expected in the service life is simulated in a streamlined manner. Common specified rates of change are 2 K/min or 4 K/min. For this purpose, the test specimen is placed in an appropriately powerful climatic chamber. Basic test standards are DIN EN 60068-2-14 and ISO 16750-4. In the automotive standards LV124, VW 80000, GS 95024-3-1 and MBN 10306 this test is known as L-03.
