The step temperature test simulates the operation of the component at different ambient temperatures. It is used to safeguard the product against malfunctions that may occur within a small interval of the ambient temperature range. The starting behavior of the product is also tested over the complete ambient temperature range. Basic test standards are DIN EN 60068-2-1 and DIN EN 60068-2-2 as well as ISO 16750-4. In the automotive standards LV124, VW 80000, GS 95024-3-1 and MBN 10306 this test is known as K-02.
