Abstract

The invention relates to an aging testing method for simulating the practical operation environment of a rubber sealing ring. The method comprises the steps of applying stress to the rubber sealing ring, applying salt spray to the rubber sealing ring, applying high temperature to the rubber sealing ring, and applying low temperature to the rubber sealing ring. The method has the benefits that the salt-spray corrosion, stress effect and high and low temperature environment of the rubber sealing ring in the practical environment are sufficiently taken into account, the test process is more closer to the practical operation environment of the rubber sealing ring, and the test result is more accurate.
