The object of this test method is to determine the tension set characteristics of elastomeric test pieces of defined shape or of complete test samples, after these have been stretched to s specified strain. It is intended to measure the ability of elastomers of hardnesses within the range (30 ... 94) Shore A (IRHD) to retain their visco- elastic properties after extension at (+23 ± 5) °C to a specified strain, which is maintained for a specified period at (+23 ± 5) °C or at a specified higher temperature and then cooled (if wanted) in the stressed or unstressed condition to (+23 ± 5) °C.
