This standard specifies the method for accelerated aging tests of vulcanized rubber through the combination of high temperature and pressurized air. It primarily simulates harsh environments to evaluate the durability of rubber under the combined long-term effects of heat, oxygen, and pressure. The core testing instrument required to perform this test is a pressurized air thermal aging test chamber, which provides constant high-temperature air and controls internal pressure. After the test, equipment such as a hardness tester and a universal material testing machine are typically used to quantitatively measure changes in key physical properties of the specimens (such as hardness and tensile strength) before and after aging, in order to scientifically assess their aging resistance.
