Projekta Nr.ISO 6914:2008
Nosaukums<p>ISO 6914:2008 describes three methods for the measurement of the change of stress in a test piece at a given elongation for the purpose of determining the ageing characteristics of a rubber.</p> <ul> <li>Method A is intended for measurement under continuous strain conditions.</li> <li>Method B is the preferred method for measurement under intermittent strain conditions.</li> </ul> <p>In the case of both methods A and B, a stress relaxometer is used to record the stress at the temperature of ageing.</p> <ul> <li>Method C is an alternative to method B for measurement under intermittent strain conditions in which the test piece is removed from the ageing environment for measurement of the stress at standard laboratory temperature.</li> </ul> <p>No agreement between the three methods should be inferred. The method used will depend on the purpose of the test.</p>
