This SAE Aerospace Standard (AS) establishes the requirements for polytetrafluoroethylene (PTFE) hose assemblies for use in aerospace hydraulic systems at temperatures between -55 °C and 204 °C and at a nominal pressure up to 28,000 kPa (280 bar). The hose assemblies are also suitable for use within the same temperature and pressure limitations in aerospace pneumatic systems where some gaseous diffusion through the wall of the PTFE liner can be tolerated. The use of these hose assemblies in high pressure pneumatic storage systems is not recommended. In addition, installations in which the limits specified herein are exceeded, or in which the application is not covered specifically by this document, for example, oxygen, shall be subject to the approval of the purchaser.
This SAE Aerospace Standard (MA) defines the requirements for a convoluted polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in aircraft fluid systems at temperatures of -55 to 204 °C and at operating pressures per Table 1.
This SAE Metric Aerospace Recommended Practice (MAP) establishes the requirements for preparing a specification for fluid couplings for spacecraft servicing. The objective of this document is to provide design, development, verification, storage, and delivery requirement guidelines for the preparation of specifications for fluid couplings and the ancillary hardware for use with serviceable spacecraft designed for use in the space environment. The couplings shall be capable of resupplying storable propellants, cryogenic liquids, and gases to a variety of spacecrafts.
This international standard establishes flexure and pressure impulse test procedures for determining and classifying the fatigue strengths of bent aircraft hydraulic tubing. The procedures are intended for use with high- and low-pressure system assemblies for evaluation of new materials or for qualification purposes.
This specification covers lightweight hose assemblies intended for use in high-temperature, 204 °C, high-pressure, 21 000 kPa (210 bar) aircraft hydraulic systems, also for use in pneumatic systems which allow some gaseous diffusion through the PTFE wall.
