This document specifies a method for determining the indentation hardness (Shore hardness) of vulcanized or thermoplastic rubber using durometers with the following scales:
— 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;
— the AM scale for thin rubber test pieces in the normal-hardness range.
