DESCRIPTION
This standard BS ISO 3384-1:2019 - TC Tracked Changes. Rubber, vulcanized or thermoplastic. Determination of stress relaxation in compression is classified in these ICS categories:
  • 83.060 Rubber

This document specifies two procedures for determining the decrease in counterforce exerted by a test piece of vulcanized or thermoplastic rubber which has been compressed to a constant deformation and maintained thus at a predetermined test temperature.

The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one.

Two test methods are specified, method A and method B. In method A the compression and all measurements of counterforce are made at test temperature and in method B the compression and all measurements of counterforce are made at standard laboratory temperature.

Method A and method B do not give the same results, as in method B the shrinkage of the material from the test temperature to standard laboratory temperature is included in the result.

Two forms of test piece are specified in this document: cylindrical test pieces and rings. Comparison of results is valid only when made on test pieces of similar size and shape.

The use of ring test pieces is particularly suitable for the determination of stress relaxation in liquid environments.

This document deals only with testing at constant ambient or elevated temperature. Testing at temperatures below standard laboratory temperature is not specified. The methods have been used for low?temperature testing, but their reliability under these conditions is not proven.
