    Abstract - (Show below) - (Hide below)

    Procedures to evaluate the effect of mineral based and fire-resistant hydraulic fluids upon three basic types of elastomeric compositions by measurement, under controlled conditions, of physical properties of standard test pieces of the appropriate test elastomer before and after immersion in the fluids.
