Scoep：
This test method covers twelve types of rubber hardness measurement devices known as durometers: Types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. The procedure for determining indentation hardness of substances classified as thermoplastic elastomers, vulcanized (thermoset) rubber, elas- tomeric materials, cellular materials, gel-like materials, and some plastics is also described. 1.2 This test method is not equivalent to other indentation hardness methods and instrument types, specifically those described in Test Method D1415.
