The constant load test is mainly designed for quality control and measurement of curing state of thin-walled products. For these, ISO 8013 applies and there is no agreement between the results of this test and the results of ISO 8013. Test methods are intended to measure the elastic properties of rubber in the hardness range of 20 IRHD to 94 IRHD.Ĭreep measurement is not intended for product design or the evaluation of low creep materials. The constant elongation test aims to measure the ability of rubbers to retain their elastic properties after being stretched to a certain strain at a standard laboratory temperature, which is held at the same or a certain elevated temperature for a certain period of time and then released.Ĭonstant load testing specifies a method for determining the elongation, creep, and stress set of rubbers subjected to a constant load at standard laboratory temperature. This standard specifies a set of methods for determining dimensional changes in test pieces of vulcanized or thermoplastic rubber during and after tensile loading for relatively short periods under constant elongation or constant loading. ISO 2285 Rubber, Vulcanized or Thermoplastic - Tension Set Under Constant Elongation and Tension Set Under Constant Tensile Load, Determination of Elongation and CreepĮUROLAB laboratory provides testing and compliance services within the scope of ISO 2285 standard.
