This SAE Recommended Practice applies to determining worst-case fuel or test fluid surrogate, conditioning test specimens in worst-case fuel(s)/surrogate(s) prior to testing, individual tests for properties of polymeric materials exposed to oxygenate fuel/surrogate mixtures with additives. The determination of equilibrium, as well as typical calculations are also covered.

Polymeric materials are used in applications that require exposure to a variety of fluid environments. Tests to determine the effects of such exposure on material properties are well established. However, the determination of the effects onpolymeric materials exposed to fuels of variable blends with assorted oxygenates poses new problems. This document seeks to address those concerns by detailing changes to standard tests that make them suitable for that purpose.
