What does Shore Hardness mean? How is Rubber Hardness

Shore (Durometer) Hardness is a measure of the resistance a material has to indentation.Named after its inventor,Albert Ferdinand Shore,Shore hardness offers different scales for measuring the solidity of different materials.(Shore was born in 1876 and lived until 1936,creating the Shore scale in the 1920s.)What is Durometer? Elastomer and Plastic Hardness ISMThe ASTM D2240 standard actually recognizes twelve different Shore durometer scales for testing rubber hardness.The most common Shore durometer scales used are Shore OO,Shore A and Shore D.Shore OO measures extremely soft rubbers and gels.This is why it is much less common to see OO durometers in relation to flow control componentsWhat is Shore Hardness? Sealing Contamination ControlShore Hardness is measured with a durometer test instrument to determine how a given material resists permanent indentation.The test method designation is ASTM D2240 and is generally used in North America.Related methods include ISO 7619.
