Heat Ageing

Test technical Basics and interesting Characteristics

During heat ageing a standardised specimen is exposed to hot surrounding air over a predefined constant temperature. This process takes place either with several samples in a kind of circulating air oven with fresh air supply or in cell ovens separated into samples. The assessment of materials aged in hot air is made by the comparison of important physical values (e.g. hardness, tensile strength, elongation at break, and the like) before and after ageing.
