This standard test method was prepared by NACE Task Group T-1G-17 to serve as a tool in the process of evaluating elastomeric materials for use in the oil field and other energy related areas where sour gaseous environments are encountered. It is an accelerated aging procedure similar to ASTM D 471, with additional information on sour environment testing under pressures greater than atmospheric pressure. By issuing specified test conditions, data from separate laboratories which utilize this method may be compared.

 This test method measures the ability of elastomeric materials to withstand static exposure to elevated pressure and vapor phase sour gas environments, e.g., gaseous hydrocarbons with hydrogen sulfide, and is not designed to be an immersion or a functional test. It is designed for testing O-rings or specimens of elastomeric vulcanites cut from standard sheets (see ASTM D 3182). The method is not applicable to the testing of cellular rubber or porous compositions.
