The permeati of Hethyi Pert iary flutyl E er (MTBE) and Tertiary Amyl Methyl Ether AME), in Titeflex connects was not measured. However because of their molecular structure, TAME and MTBE will ' than Ethanol and Methanol. Test results for Ethanol and Methanol were well with in UL's requirements. MATERIAL COMPATIBILITY UL fluid compatibility testing evaluates the effect of prolonged exposure on both component parts and finished assemblies. Two categories of fluids are used in testing: Type A fluids, which are intended to represent the actual application; and Type B flu-ids, which are far more demanding. Type A Fluids- 270 day exposure at ambient temperatures Premium leaded gasoline Regular unleaded gasoline No. 2 fuel oil ASTM Reference Fuel C Sulfuric Acid Saturated sodfum chloride- 100% 100� Ethanol 100% Methanol 10% Ethanol-90% Fuel C 30% Ethanol-70x Fuel C 15% Ethanol-85% Fuel C 5095 Ethanol-509: Fuel `c No. 6 fuel oil 509 Methanol-5091 Fuel C 15% Methano1-85% Fuel C Tvoe g lui - 180 day exposure at ambient temperature Distilled Water 1% Nitric Acid 1% Hydrochloric Acid y 100% Toluene Sodium Hydroxide Sodium carbonate-sodium bicarbonate After exposure to Type A Fluids, Type 0 Fluids, and Air Oven Aging Tests: individual components are tested to determine the percent retention of original material properties (i.e. crush and tensile strength) ; hose assemblies are subjected to a hydrostatic strength test, and then burst. The acceptance criteria for components in Type -A Fluids is a 50% minimum retention of material properties; Type B Fluids is a 30% minimum retention; and Air Oven Aging requires an 80%, minimum retention_ The criteria for assemblies (after Type A, Type 8 and Air Oven Aging) is a Hydrostatic Strength Tes C at five times rated operating pressure.
