This standard establishes a test method to measure the effect on elastomeric materials subjected to rapid depressurization from elevated pressures in dry CO2 environments. It is designed for testing O-rings or other specimens of elastomeric vulcanizates. This test method is not applicable to the testing of cellular rubber or porous materials.

This standard recommends procedures for the preparation of test specimens, the test equipment to be used, the test procedures to be followed, and the reporting of test results. The results are determined by monitoring changes in physical and mechanical properties as well as changes in appearance after exposure to the selected test media.
