Title:Methods for Determining Physical Properties of Polymeric Materials Exposed to Gasoline/Oxygenate Fuel Mixtures
Issuing Committee:Fuel Systems Standards Committee
Scope:This SAE Recommended Practice applies to determining worst-case fuel, conditioning test specimens in worst-case fuel(s) prior to testing, individual tests for properties of polymers exposed to methanol-gasoline fuel mixtures. The determination of equilibrium, as well as typical calculations are also covered.Polymers are used in applications which 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 polymers exposed to fuels of variable alcohol and ether content poses new problems. This document seeks to address those concerns by detailing changes to standard tests that make them suitable for that purpose.Product Code:SAE AIR887
Title:Liquid Filter Ratings, Parameters and Tests
Issuing Committee:A-6c1 Contamination And Filtration Committee
Scope:This SAE Aerospace Information Report (AIR) identifies and explains the meaning of various ratings and terms used to describe the physical characteristics of liquid filter elements. The significance of various filter parameters is discussed. In addition, a number of filter test methods are briefly described. This AIR and the data presented are only applicable where the system liquid wets the filter elements.
