BS ISO 48-4:2018

This standard BS ISO 48-4:2018 Rubber, vulcanized or thermoplastic. Determination of hardness is classified in these ICS categories:

• 83.060 Rubber

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.
