WebSep 20, 2016 · The Shore A hardness measurement is often colloquially called “durometer” or “duro”. This test is performed on cured rubber sheets per ASTM D2240, and on finished O-rings per ASTM D1414. The device consists of a hardened steel rod with a truncated cone at the tip. The steel rod is spring-loaded and actuates a dial with a scale of 0 to 100.
