Compared to the everyday use of the components, higher temperatures are often used here to accelerate reactions.<\/p>\n<h4>Significance for Application Technology<\/h4>\n<p>Based on the results of heat ageing tests, statements can be made about the temperature resistance of a material without the influence of contact media. In addition, the results can be used to estimate the expected service life of the tested materials under certain conditions of use. In combination with other tests, the results of heat ageing also allow an evaluation of the compounds and processing quality of elastomers.<\/p>\n<h4>The Heat Ageing Test<\/h4>\n<p>Different methods of heat ageing, hence artificial ageing, of rubber and elastomers are defined, among others, in the standards ISO 188, DIN 53508, ASTM D 573 or ASTM D 865.<\/p>\n<p>During heat ageing, a standardised test specimen is exposed to hot ambient air for a defined period of time and at a defined temperature. Depending on the method, this is done with or without a supply of fresh air.<\/p>\n<p>The supply of fresh air, that is, additional oxygen, during the test causes additional stress on the specimen and usually leads to stronger or faster reactions. In contrast, reactions with atmospheric oxygen in a closed atmosphere without additional air supply can come to a standstill after the available oxygen has been fully used. Both test variants have their justification with regard to technical applications.<\/p>\n<p>The actual evaluation of the materials is done using some important, physical basic properties, for example hardness or tensile strength and elongation at break. These are tested before and after the heat ageing process and the results are compared with each other.<\/p>\n<\/div><\/section><\/div>\n<\/p>\n<\/div><\/div><\/div><!-- close content main div
