This Committee is responsible for developing and maintaining standards for design, test, and procurement of fluid systems part standards to improve reliability and economy. Their primary focus is on AS standards development and support of military standards. The Committee also develops ISO standards in a Subcommittee Advisory Group (SCAG) to ISO/TC 20/SC 10, and SAE-MA derivatives thereof.

Structure:

SAE G-3 -- Parent committee

SAE G-3A -- Aerospace Couplings Subcommittee

SAE G-3B -- Aerospace Fittings Subcommittee

SAE G-3D -- Aerospace Hose Subcommittee

SAE G-3E - Aerospace Tubing Assemblies Subcommittee

U.S. SCAG to ISO/TC 20/SC 10 -- ISO standards

Major projects:

Support of Military Standards Reform

Support of military standard conversions to MIL-PERF and MIL-DTL.

Development of AS replacements for military standards designated for conversion.

Establish document to list G-3 accepted replacements for replaced part standards and military back-up specifications.

Development of PRI QML/QPL Development of Performance Review Institute (PRI) process for approval and surveillance of manufacturers (Qualified Manufacturer List, QML) and for approval of standard parts as qualified for use (Qualified Parts List, QPL).

Development of ISO Standards, Imperial Units ISO/TC 20/SC 10 standards have typically been developed in SI units. The ISO has approved development of inch-based ISO standards to support commercial aviation. Basic design, test, and procurement specifications will be selected from military standards that are to be converted to Non-Government standard (NGS) and developed as ISO standards.
