KS M ISO 3384-2:2014 Rubber, vulcanized or thermoplastic — Determination of stress relaxation in compression — Part 2: Testing with temperature cycling
This standard specifies two methods for measuring the reduction in resistance exhibited by vulcanized or thermoplastic rubber test specimens compressed to constant strain and subjected to temperature cycling. Method A: Temperature ranges between a high temperature for aging and a low temperature to determine sealing strength. Method B: The temperature is continuously cycled between high and low temperatures to introduce thermal stress in the test specimen. Resistance is measured using a continuous measurement system. The test specimen is divided into a cylindrical specimen and an annular specimen. are distinguished. Different shape and size of test specimens will result in different test results, so comparisons of results should be limited to test specimens of similar size and shape. The use of ring-shaped test specimens is particularly suitable for stress relaxation measurements in liquid environments.
