SAE J1748 2007 Edition, September 1, 2007
Methods for Determining Physical Properties of Polymeric Materials Exposed
to Hydrocarbon Fuels or Their Surrogates and Their Blends with Oxygenated
Additives
Description / Abstract:
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.
Purpose
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 on polymeric 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.
