Abstract:

Many of the materials used for tactical fuel handling equipment were designed for use with petroleum-derived fuels, such as diesel and JP-8, which typically contain 15-25 aromatics. However, emerging synthetic turbine fuels based on iso-paraffinic kerosene IPK, synthetic paraffinic kerosene SPK, and Hydroprocessed Esters and Fatty Acids HEFA typically contain no aromatics. Many of these fuels have undergone extensive testing and gained approval for use by the Air Force. As these fuels become more widely available and their use extends to ground vehicles and support equipment, their impact on current Army equipment will need to be assessed. ASTM D381 is currently used in specifications for military fuel hoses MIL-PRF-370J and collapsible fuel tanks MIL-PRF-32233. This test method is used to determine if any material in contact with aviation fuels or motor gasolines causes gum contamination. This study addresses various aspects of the ASTM D381 method as a means to determine gum contamination of fuel in contact elastomeric and rubber materials.
