Aerospace Standard Test Methods for Aerospace Sealants Two-Component Synthetic Rubber Compounds
2014-10-08
HISTORICAL
AS5127/1C
This SAE Aerospace Standard (AS) describes test methods to determine the application and performance properties of two-component sealing compounds. It shall be used in conjunction with AS5127 and the applicable material specification. When modifications to these test methods are called out in material specifications, the material specification shall take precedence.

JET REFERENCE FLUID STUDY FOR FUEL TANK SEALANTS
1991-04-01
HISTORICAL
AIR4275
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.

Jet Reference Fluid Study for Fuel Tank Sealants

CURRENT
AIR4275B
This information report covers two distinct projects to formulate Jet Refrence Fluids (JRF) for testing of material compatibility. The first effort began in 1978 and focused on producing a formulation (JRF-2) that simulated JP-4 and included composition with metallic ions that reproduced chalking of fuel tank sealants. This effort resulted in the preparation of AMS2629 that defined the formulation of JRF-2 (Type 1) and the same formulation with metallic ions (Type 2). The second effort began in 2002 and focused on preparing a JRF that simulated Jet A, JP-5 and JP-8. This effort went through multiple iterations, but eventually resulted in a JRF-3 formulation composed of Jet A plus military additives spiked to 25% aromatic content and high levels of sulfur experienced in the global fuel supply. Since the metallic ions added to JRF-2 demonstrated their ability to simulate a chalking reaction, chalking was not tested with the ions added to JRF-3.
