ISO 7619-1:2010 specifies a method for determining the indentation hardness (Shore hardness) of vulcanized or thermoplastic rubber by means of durometers using the A scale for rubbers in the normal-hardness range; the D scale for rubbers in the high-hardness range; the AO scale for rubbers in the low-hardness range and for cellular rubbers; and the AM scale for thin rubber test pieces in the. Measuring the Hardness of Applied Coatings Introduction The hardness of a coating material is a relative property that may be interpreted in a variety of ways by different industries that use coating/lining materials. There was a hardness [=toughness] in her voice I hadn't heard before.
