| Published By | Publication Date | Number of Pages |
| BSI | 2018 | 24 |
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.
