AIR1168/10A
This AIR is arranged in the following two sections: 2E - Thermodynamic Characteristics of Working Fluids, which contains thermodynamic diagrams for a number of working fluids currently in use and supplied by various industrial firms. 2F - Properties of Heat Transfer Fluids, which contains data, primarily in graphical form, on fluids that are frequently used in fluid heat transfer loops. Other properties of the environment, gases, liquids, and solids, can be found, as follows, in AIR1168/9: 2A-Properties of the Natural Environment 2B-Properties of Gases 2C-Properties of Liquids 2D-Properties of Solids

AS85720B
This specification covers the design requirements and test procedures for separable beam seal fittings which include end fittings (see 2.4.2), connectors (see 2.4.3), and boss fittings for use in aerospace fluid systems. Design requirements are for Class 5000 and 8000 in titanium, and corrosion resistant steel (CRES). Definition of fittings and related terms are defined in 2.4.

ARP6157
The lubricant performance capability for aero propulsion drive systems is derived from the physical properties of the oil and performance attributes associated with the chemical properties of the oil. Physical properties, such as viscosity, pressure-viscosity coefficient and full-film traction coefficient are inherent properties of the lubricating fluid. Chemical attributes are critical for the formation of protective boundary lubricating films on the surfaces to prevent wear and scuffing. These attributes are also associated with surface initiated fatigue (micropitting). To assure performance and to provide required information for engineering design, methodology for at least five oil properties are being studied: (1) pressure-viscosity coefficient, (2) full-film traction coefficient, (3) scuffing resistance, (4) wear resistance; and (5) micropitting propensity.

ARP584D
This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies ranging from 1/4 inch (6.3 mm) to 1.0 inch (25 mm) diameter using CRES tubing per AMS-T-6845, unless otherwise approved by the Procuring Activity. This ARP specifically details three different configurations of coiled tubing. These configurations should be compatible with pressure levels up to 3000 psi (20.7 MPa) upon the completion of the analysis for the actual stress and life requirement of the intended application. However, formal qualification tests are recommended to verify the satisfactory installation, clamping, and the life of each unique design. NOTE: Refer to ARP4146 for information on design of coiled tube assemblies using Titanium tubing.

AS5830A
This aerospace specification defines the requirements for a threadless, flexible, conductive, self-bonding coupling assembly which, when installed on fixed cavity ferrules, provides a flexible, current carrying connection for joining tubing and components in aircraft fuel, vent and other systems. The assembled coupling is designed to provide interchangeability of parts and components between qualified manufacturers for the service life of the aircraft system. The assembled coupling is for use from -65 to +200 °F at nominal operating pressures (125 psig for -08 through -64 and 30 psig for -72 through -88). This aerospace specification is a departure from prior qualification practices for assembled couplings. Prior practice sought to validate this type of assembled coupling design by conducting a sequence of tests on sets of coupling assemblies. There were multiple test sequences and each was conducted on a different set of coupling assemblies.

AMS3284C
This specification covers a polysulfide sealing compound with low adhesive strength. This elastomeric compound shall be supplied as a two-component system which cures at room temperature. This compound has been used typically for sealing aircraft access doors and accessories where gaskets are required, but usage is not limited to such applications. The sealing compound is resistant to jet fuels and high aromatic aviation gasolines and is usable from -65 to 250 °F (-54 to 120 °C).
