Jet Reference Fluid Study for Fuel Tank Sealants

AIR4275B
Standard reference fluids, or test fluids, have long been used to evaluate the effects of hydrocarbon fuels on various materials, such as integral fuel tank sealants. Standard fluids are required because hydrocarbon fuels, such as JP-4, vary widely in composition depending on crude source, refining techniques, and other factors. To ensure reliable and reproducible results when determining the fuel resistance of materials, reference fluids of known composition, using worst case fuel compositions, are used. The current Jet Reference Fluid (JRF) called out in military sealant specifications was developed in the mid-1950s specifically as a JP-4 type test fluid formulation to be used for the accelerated laboratory testing of integral fuel tank sealants. In August 1978, chalking of the polysulfide sealant in integral fuel tanks of some new aircraft at Edwards Air Force Base in California was discovered after only 1 year of service.

Sealing of Integral Fuel Tanks

CURRENT
AIR4069C
This SAE Aerospace Information Report (AIR) presents preferred design, assembly, and repair practices for sealing of aircraft integral fuel tanks, including rework of applied fuel tank seals. It addresses engineering designs for integral fuel tanks as they are currently found in practice; and discusses the most practical and conservative methods for producing a reliable, sealed system. Although this AIR presents practices for sealing of integral fuel tanks, the practices presented within this report are practices that are carried throughout sealing that include both pressure and environmental aircraft sealing. Design preferences for optimum sealing are not within the scope of this document. Such discussions can be found in the United States Air Force (USAF) sponsored report, entitled Aircraft Integral Fuel Tank Design Handbook, AFWAL-TR-87-3078.
