Thermal testing is a research area that focuses on studying how materials and systems behave under different temperature conditions. This can include testing the thermal properties of materials, such as conductivity and diffusivity, as well as evaluating the performance of devices and systems at various temperatures. Thermal testing is important in a wide range of industries, including electronics, aerospace, and automotive, as it helps researchers ensure that products can withstand the temperature fluctuations they may encounter in real-world applications. This research area also involves developing testing methods and equipment to accurately measure and analyze thermal properties and performance.
