Omfattning
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.
