Insulating Compound, Electrical, Embedding, Reversion Resistant Silicone

CURRENT
AS81550B
This specification covers the requirements for two types of a two-part, transparent, reversion resistant flexible insulating compound, to provide resilient, environmental, and electrical insulation of components in systems in temperature range -85 to 392 °F (-65 to 200 °C). These insulating compounds are intended for embedding, potting or encapsulation of electrical and electronic components in systems where tear resistance is not critical, but their use is not limited to such applications. These transparent compounds allow visual circuit and part identification and facilitate part replacement and repairs. The insulating compound shall cure in sections of unlimited thickness, either exposed to air or completely sealed.

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.
