Abstract
Methods for performing seal validation with a chemical pre-treatment are provided. One such method includes establishing an Arrhenius relationship between a material property response of a material exposed to a test fluid based on experimental results of testing a plurality of material samples made of the material across multiple temperatures. The method also includes determining, based on the Arrhenius relationship, a pre-treatment time and a pre-treatment temperature that approximates a seal end-of-life condition. The method further includes pre-treating a seal by exposing the seal to the test fluid at the determined pre-treatment temperature for the determined pre-treatment time, the seal having at least in part a same material composition as the plurality of material samples, and after pre-treating the seal, performing one or more validation tests on the pre-treated seal.
