ARP4741A
This SAE Aerospace Recommended Practice (ARP) establishes the requirements for the design, manufacture, and qualification of four hydraulic switching valves used in airborne applications. Two are pressure operated, Type IA and IB and two are solenoid/pilot operated, Type IIA and IIB. They are applicable to four pressure classes 3000, 4000, 5000 and 8000 psi. The equipment as designed is intended to be installed in hydraulic systems designed to AS5440 for military applications or ARP4752 and ARP4925 depending on the type of aircraft for commercial applications. Additional or refined requirements shall be contained in the detail (procurement) specification and these shall take precedence over any potentially conflicting requirements of this ARP or documents referenced by this ARP.

AS5781A
This SAE Aerospace Standard (AS) covers scarf-cut polytetrafluoroethylene (PTFE) retainers (backup rings) for use in glands in accordance with AS4716. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals for static and dynamic applications. Because of the construction of groove dimensions, backup rings specific to rod applications are designated "R" ~ Rod (Female), backup rings specific to piston applications are designated "P" - Piston (Male). Piston and rod types of virgin pigmented PTFE are also identified by color code which also distinguishes parts to this standard from those made from virgin PTFE to other standards. Backup rings specified herein have been designed for a temperature range of -65 to 275 °F (-54 to 135 °C) and a nominal operating pressure of 3000 psi (20.7 MPa) for code 09 material (AMS 3678/9). Alternate materials to AMS 3678 are offered for more arduous operating conditions.

AS6235A
This SAE Aerospace Standard (AS) specifies standardized gland design criteria and dimensions for static face seals for internal pressure and external pressure applications for aerospace hydraulic and pneumatic applications using the same size range as AS4716 and AS5857 where applicable. Some small diameter sizes are excluded because they are not practical. The glands have been specifically designed for applications using AS568 size elastomeric O-rings with related Class 2 tolerances at nominal system operating pressures up to 3000 psi (20 680 kPa) utilizing no anti-extrusion (backup) rings. While the gland dimensions herein have been designed for pressures up to 3000 psi (20 680 kPa) these glands may be used for higher pressures, but extra precautions need to be taken and testing should be performed to ensure to ensure integrity of performance. This specification covers the basic design criteria and recommendations for use with standard size elastomeric O-rings, however, these glands are also suitable for use with other elastomeric and polytetrafluoroethylene (PTFE) based seal geometries.

ARP5312
The recommended test method applies to hydraulic actuators that are components of commercial and military aircraft control systems. This recommended practice establishes guidelines for comparison testing and reporting the effectiveness of rod scrapers only against dry dust and ingression of ISO standardized test dust into the fluid and should not be construed as a qualification process for rod scrapers since the macro contaminants which are not being tested here can affect scraper performance. To fully evaluate rod scraper effectiveness, the subject actuator design and its full operating environment needs to be evaluated.
