IEC 60068-2-14: Change of Temperature test standard is an international standard developed by the International Electrotechnical Commission (IEC). This standard outlines the testing procedure for assessing the ability of components, equipment and other articles to withstand rapid changes in temperature. It is particularly relevant for items that might be exposed to such conditions during their normal service life. The test involves subjecting the item to sudden changes in temperature, often from one extreme to another, to simulate the conditions it may encounter in real-world environments. The item is placed in a test chamber, where the temperature is rapidly changed between two extremes for a specified number of cycles. The severity of the test, including the rate of temperature change and the temperature extremes, is determined based on the expected conditions the item will face during its service life. The purpose of this test is to determine any harmful effects caused by rapid temperature changes, such as mechanical damage or changes in the item's operational characteristics. This standard is widely used in industries such as electronics, automotive, aerospace, and defence, where equipment is often exposed to harsh and rapidly changing environmental conditions.
