GB/T 27800-2021 specifies a general method for rapidly predicting the service life of static sealing rubber products through accelerated aging tests. This method is based on the Arrhenius model, extrapolating the service life under normal operating temperatures by testing the changes in key rubber properties (such as compression set and hardness) under aging conditions such as high temperatures. The standard regulates the test equipment, specimens, aging procedures, and life calculation. The relevant testing primarily relies on aging test chambers capable of precise temperature control (such as hot air aging ovens) and requires the use of performance testing instruments like durometers and compression stress relaxometers.
