This standard test method is intended 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 liquid environments are encountered. This standard sets forth procedures to measure the ability of elastomeric materials to withstand static exposure to sour liquid environments (e.g., hydrocarbon, water, or mixtures of each with hydrogen sulfide [H2S]) at elevated pressure and temperature. This standard is maintained by Task Group 087.
