This standard establishes a test method to measure the ability of elastomeric materials to withstand static exposure to vapor phase sour gas environments (e.g., gaseous hydrocarbons with hydrogen sulfide [H2S]) at elevated pressure. This test method is not designed to be an immersion or a functional test. It is designed for testing standard O-rings or test specimens of elastomeric vulcanites cut from standard sheets (see ASTM D31822). This test method is not applicable to testing cellular rubber or porous materials.
