This part 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 cellular rubbers;
the AM scale for thin rubber test pieces in the normal hardness range.
2. Normative references
The following normative documents contain provision which, through reference in this text, constitute provisions of this national standard. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. But the parties to agreements based on this standard are encouraged to investigate the possibility of applying the latest editions of the standards indicated below. For undated references, the latest edition of the normative document referred to applies.
