IRHD (International Rubber hardness Degrees)
Posted on 31/12/2018 Category:
A system of characterising an elastomer by its resistance to penetration of a known geometry indenter by a known force. This micro technique is reproducible on irregular as well as flat surfaces and on cross sections as small as 1mm in thickness (.04″). Measurements taken using the IRHD scale are similar, but not identical, to those obtained using the Shore A scale.
