Thus, it is possible to evaluate and compare different elastomer formulations. If the tests are carried out at different temperatures for an appropriate length of time, we can also use the compression set values to assess the long-term behaviour of the elastomer components or provide a service life straight line.<\/p>\n<h4>The Compression Set Test<\/h4>\n<p>The compression set is usually tested according to the standards ISO 815-1, DIN ISO 815-1 (this replaces DIN 53517, which is still noted in old data sheets or specifications) or ASTM D395. The CS test procedure is carried out at either ambient or elevated temperatures, depending on the standard and requirements. Measurements at low temperatures are defined in (DIN) ISO 815-2 (see also compression set at low temperatures). The CS can be determined both with standard test specimens as well as with finished parts.<\/p>\n<h4>General Procedure of the CS test in accordance with relevant standards<\/h4>\n<p>In the standardised CS test with elevated temperature, a precisely defined elastomer specimen is<\/p>\n<ul>\n<li>measured at its initial height<\/li>\n<li>compressed in a defined manner using a device, usually by 25 % of its initial height<\/li>\n<li>exposed to a defined temperature for a defined period of time, often 24 hours, in a laboratory oven in the compressed state<\/li>\n<li>then released and cooled in a defined way (depending on the method, cooling takes place in the compressed or in the released state)<\/li>\n<li>and measured at its new height after a defined time<\/li>\n<\/ul>\n<p>The compression set describes the remaining part of the initially applied compression in percent. It therefore refers to the deformation trajectory and not, as often assumed, to the initial height of the specimen.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\"
