This SAE Aerospace Recommended Practice (ARP) establishes a method for evaluating the particulate matter extracted from the working fluid of a hydraulic system or component using a membrane. The amount of particulate matter deposited on the membrane due to filtering a given quantity of fluid is visually compared against a standard membrane in order to provide an indication of the cleanliness level of the fluid
This AIR presents an abbreviated review of the metallurgical phenomena known as whiskers. It is not all encompassing; rather, it is intended to introduce the design engineer to the technical issues of metallic whiskers, their formation, and the potentially dangerous problems they can cause

This document defines the test procedures and performance limits of steady state and transient voltage characteristics for 12 V, 24 V, or 48 V electrical power generating systems used in commercial ground vehicles
This specification covers a nickel alloy in the form of wire, rod, strip, foil, and powder and a viscous mixture (paste) of the powder in a suitable binder
This SAE Aerospace Recommended Practice (ARP) covers the design and installation requirements for hydraulic systems (up to 8000 psig [56 MPa]) for ground support equipment (GSE). This ARP is derived from AS5440, which provides hydraulic system requirements for aircraft. The recommendations herein are primarily intended for GSE that exchange hydraulic fluid with the aircraft, such as hydraulic service carts, rather than GSE with non-interfacing hydraulic systems. The GSE may be mobile, portable, or stationary
With many corporations and suppliers conducting development and validation tests at different climatic wind tunnel sites, there is an increasing need for a recommended best practice that defines a process by which climatic wind tunnels can be correlated. This document addresses the test methods and metrics used to correlate results from different facilities, independent of location, for heating ventilation and air conditioning (HVAC) and powertrain cooling (PTC) development. This document should be used as a guideline to make sure key aspects of tunnel testing are covered when comparing various climatic wind tunnel facilities. The depth of the correlation program is ultimately influenced by program objectives; therefore, a correlation program, for the intent and purposes of this document, can range from just a few tests to a full analysis that involves multiple vehicle tests identifying limitations and statistical boundaries. Using recommendations in this document will eliminate most
This specification covers a titanium alloy in the form of round, hexagon and square bars and forgings up through 3.000 inches (76.20 mm), inclusive, rectangular bar and forgings of thickness up through 4.000 inches (101.60 mm), inclusive, and forging stock of any size (see 8.6
This SAE Aerospace Standard (AS) establishes the requirements for straight threaded boss or flanged fluid connection fittings (see Section 6) for use in all types of fluid systems
This specification covers an aircraft-quality, low-alloy steel in the form of seamless mechanical tubing
This SAE Aerospace Standard (AS) defines the requirements for a threadless, flexible, high conductive, self-bonding coupling assembly which, when installed on defined ferrules, provides a flexible connection for joining ducting and components in pressurized fluid systems. The assembled coupling is designed to provide interchangeability of parts and components between qualified manufacturers for use from -65 to +265 °F at 130 psi nominal operating pressures and for the service life of the aircraft system. FAR 23.954, FAR 25.603, FAR 25.605, FAR 25.609, FAR 25.613, FAR 25.901, FAR 25.954, and FAR 25.981 certification requirements have identified the need for high-current capable flexible fluid assembled couplings. The coupling assembly does not require inspection or maintenance to remain current capable for the life of the aircraft. This specification provides two test philosophies necessary for low-pressure couplings: 1 Electromagnetic effects/lightning testing of assembled couplings to

SAE J1978/ISO 15031-4 specifies a complementary set of functions to be provided by an OBD-II scan tool. These functions provide complete, efficient, and safe access to all regulated OBD (on-board diagnostic) services on any vehicle which is compliant with SAE J1978/ISO 15031-4. The SAE J1978 content of this document is intended to satisfy the requirements of an OBD-II scan tool as required by current U.S. on-board diagnostic (OBD) regulations. The ISO 15031-4 content of this document is intended to satisfy the requirements of OBD requirements in countries other than the U.S., and includes functionality not required or not allowed in the U.S. This document specifies: A means of establishing communications between an OBD-equipped vehicle and an OBD-II scan tool. A set of diagnostic services to be provided by an OBD-II scan tool in order to exercise the services defined in SAE J1979/ISO 15031-5. SAE J1978/ISO 15031-4 does not preclude the inclusion of additional capabilities or functions
SAE J515 covers the specification for hydraulic O-ring material and properties and sizes applicable to face seal fittings, metric and inch stud ends, and four-bolt flange fittings. The standard includes a size code to allow industry and government agencies to order O-rings with a coded part number

SAE J1502 specifies dimensions, performance requirements, and test procedures for the male half of a diagnostic coupler with either a metric M14x1.5 or an inch 9/16-18 straight thread stud end. The coupler is designed for use with a mineral-based hydraulic fluid. It is used on machines specified in SAE J1116. It does not apply to the mating hydraulic quick action couplings not on the machine. Diagnostic couplings in accordance with SAE J1502 may be used at a working pressure of 42 MPa. The permissible working pressure depends upon the materials, design, working conditions, application, etc. Conformance to the dimensional information in this part of SAE J1502 does not guarantee rated performance. Each manufacturer should perform testing according to the specification contained in this document to ensure that components comply with the performance rating
