• The measuring of Shore hardness according to DIN ISO 7619-1 is the most applied measurement of the elastomer hardness. The Shore hardness gives the resistance of a rubber part towards the penetration of a cone-shaped pin with determined dimensions under a defined pressure. Shore A for softer compounds and Shore D for harder compounds is determined by the type of measuring pin. To receive a perfect measuring result of the Shore hardness the test specimen must have a thickness of 6 mm. In many cases the measurement on finished parts with a small rubber wall thickness leads to wrong results. Standard elastomer compounds for technical rubber moulded parts are lying in a range from 20 to 90 Shore A. Source: [http://www.hofftech.com Hoffmann GmbH] © With kind permission.
