This supplement forms a part of Aerospace Standard MA620, HOSE ASSEMBLIES, CONVOLUTED, POLYTETRAFLUOROETHYLENE, METALLIC REINFORCED, HIGH TEMPERATURE, MEDIUM PRESSURE, AIRCRAFT, METRIC and shall be used to identify hose assembly standards citing this procurement specification.
This specification covers three types of lightweight, low pressure, wire, or fabric reinforced hose assemblies primarily for use in aircraft potable water systems.
This document defines the requirements for a PTFE lined, aramid reinforced assembly suitable for use up to 135 °C and up to 28 000 kPa aircraft and missile hydraulic and pneumatic systems.
This Aerospace Standard (AS) defines the requirements for a lightweight polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable 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.
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.
The scope of this document is limited to the compatibility of typical fluids that may come in contact with PTFE hose assemblies. PTFE hose assemblies may be braided with CRES wire, polyester or para-aramid fibers. Hose assemblies may be equipped with aluminum, CRES, titanium or nickel alloy fittings; and with fire resistant cover materials. All of these constituent materials of PTFE hose assemblies must be compatible with all of the fluids found in any particular application.
This supplement forms a part of AS1975, Hose Assembly, Polytetrafluoroethylene, Para-Aramid Reinforced, 3000/4000 psi, 275 °F, Standard Duty, Hydraulic, Aircraft Systems and shall be used to identify hose assembly standards citing this procurement specification.
To present a summary of the guidelines and practices presently being used by the aerospace industry for the selection of coiled tubes, flexible hoses, swivel fittings, and extension fittings in aircraft fluid systems.
The scope of this SAE Aerospace Recommended Practice (ARP) is to establish the procedure for creating titles of aerospace tubing and clamp installation documents generated by SAE Subcommittee G-3E.
This SAE Aerospace Standard (AS) defines a series of standardized tube walls to be used for high pressure hydraulic tubing. These tube walls are applicable to all homogenous tube materials (i.e., aluminum, steel, titanium) throughout a rated pressure range of 1000 to 8000 psi and a maximum rated operating temperature range of 160 to 450 °F. All future aerospace applications for which a required tube outside diameter/tube wall combination is not presently available shall be selected from the table contained herein (see Figure 1).
