WIP
AMS3212R
This specification covers a nitrile (NBR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. These products have been used typically for parts, such as gaskets, diaphragms, bushings, grommets, and sleeves, requiring resistance to aromatic and aliphatic fuels when continuously or alternately exposed to both, but usage is not limited to such applications.

WIP
AMS3226J
This specification covers a nitrile (NBR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes. Primarily for hose, packings, bushings, grommets, and seals in contact with hot, petroleum-base lubricating oils and glycol-type coolants from -40 degrees to +100 degrees C (-40 degrees to +212 degrees F).
Standard

Silicone Rubber, 1000 psi (6.89 MPa) Minimum Tensile Strength, 45 - 55 Durometer

2019-10-25
WIP
AMS3345G
This specification covers a silicone rubber material that can be used to manufacture product in the form of sheet, strip, tubing, molded shapes, and extrusions.

This specification should not be used to address products such as O-rings, compression seals, O-ring cord, and molded-in-place gaskets. For these applications AMS specifications in the AMS7XXX series should be used.

Elastomer: Phenyl Methyl Vinyl Silicone (PVMQ), Low Temperature/Engine Oil Resistant, High Strength/High Tear, 55 to 65 Type “A” Hardness, For Products in Aircraft Piston Engine Oil/Low Temperature Environments

2019-10-24
CURRENT
AMS3346H
This specification covers a phenyl vinyl silicone rubber material that can be used to manufacture product in the form of sheet, strip, tubing, molded shapes, and extrusions. This specification should not be used for molded rings, compression seals, O-ring cord, and molded in place gaskets for aeronautical and aerospace applications without complete consideration of the end use prior to the selection of this material.

Minimum Performance Standard Angle of Attack Equipment

2019-10-15
WIP
AS8046A
This SAE Aerospace Standard (AS) establishes the minimum performance requirements for an angle of attack (AOA) system. This document covers two basic AOA Systems. One measures airflow and pressure distribution on the airfoil, and the other measures the angle of airflow with respect to an arbitrary reference line. Each type of system includes, as a minimum, a sensor and a display to the pilot representative of the aircraft's AOA.

Retainers, (Back-Up Rings), Hydraulic and Pneumatic, Polytetrafluoroethylene Resin, Single Turn, Static Gland

2019-10-13
WIP
AS5860C
This SAE Aerospace Standard (AS) covers scarf-cut polytetrafluoroethylene (PTFE) retainers (back-up rings) for use in static glands in accordance with AS5857. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals. Because of the construction of groove dimensions, back-ups specific to rod applications are designated “R” - Rod (Female), back-ups specific to piston applications are designated “P” - Piston (Male). Retainers 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 and 5000 psi (34.5 MPa) for code 10 material. Material codes are based on AMS3678 material types.

AS5861B
This SAE Aerospace Standard (AS) covers solid polytetrafluoroethylene (PTFE) retainers (back-up rings) for use in static glands in accordance with AS5857. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals. Because of the construction of groove dimensions, back-ups specific to rod applications are designated “R” - Rod (Female), back-ups specific to piston applications are designated “P” - Piston (Male). Retainers 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 (20 684 kPa) for code 09 material and 5000 psi (34 474 kPa) for code 10 material. Material codes are based on AMS3678 material types.

Retainers (Backup Rings), Hydraulic and Pneumatic, Polytetrafluoroethylene Resin, Single Turn, Scarf-Cut, For Use in AS4716 Glands

2019-10-13
WIP
AS5781B
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.
