ASTM F 38-00 B
RELAXATION AND CREEP TESTING
The method allows for the determination of relaxation and creep. The test is conducted using special instruments and the temperatures used are RT (Room Temperature), 100 and 200°C. Due to the characteristics and the structure of the test stand it is impossible to test gaskets, while it is possible to test material samples used in flat seals. The stands allow for performing tests of various materials – from soft elastomeric materials up to pure metal seals. The aim of the tests is to provide values regarding the rheological behavior of materials, mostly in increased temperatures.
