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.<\/p>\n

The counterforce can be determined either by means of a continuous-measurement system or by a discontinuous-measurement one.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

The use of ring test pieces is particularly suitable for the determination of stress relaxation in liquid environments.<\/p>\n

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.<\/p>\n","protected":false},"excerpt":{"rendered":"
