                            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.
