Verification of New Conductor Alloys for AS29606 Conductors Qualification

2017-11-15
CURRENT
AS6324
AS6324 specifies the requirements for comparative testing of new copper and copper alloy conductors to AS29606 qualified conductors. AS29606 approved conductors are used for the construction of insulated wire defined in SAE Aerospace wire standards (i.e., AS22759, AS81044, etc.). AS6324 defines testing which meets or exceeds the minimum test requirements of AS29606 and AS22759 and its detailed specification sheets.

WIP
AIR1662B
This SAE Aerospace Information Report (AIR) provides background information, technical data and related technical references for minimization of electrostatic hazards in aircraft fuel systems. Techniques used to minimize the electrostatic hazard include: a. Reducing fueling rate into tank bays including use of multiple refueling inlet nozzles. b. Reducing refuel plumbingn flow velocities. c. Introducing fuel into the tank at a low velocity near the bottom and directing it to impinge upon a grounded conducting surface. d. Avoiding electrically isolated conductors in the fuel tank. e. Using conductivity additives in the fuel.

Specification for Aero and Aero-Derived Gas Turbine Engine Lubricants

2017-11-14
WIP
AS5780D
This specification defines basic physical, chemical, and performance limits for 5 cSt grades of gas turbine engine lubricating oils used in aero and aero-derived marine and industrial applications, along with standard test methods and requirements for laboratories performing them. It also defines the quality control requirements to assure batch conformance and materials traceability, and the procedures to manage and communicate changes in oil formulation and brand. This specification invokes the Performance Review Institute (PRI) product qualification process. Requests for submittal information may be made to the PRI at the address in Appendix D Section D.2, referencing this specification. Products qualified to this specification are listed on a Qualified Products List (QPL) managed by the PRI. Additional tests and evaluations may be required by individual equipment builders before an oil is approved for use in their equipment.
