The test method describes the procedure for determination of the total acid number (TAN) of new and degraded polyol ester and diester-based gas turbine lubricants by the potentiometric titration technique. The method was validated to cover an acidity range of 0.05 to 6.0 mg KOH g-1. The method may also be suitable for the determination of acidities outside of this range and for other classes of lubricants.

This SAE Aerospace Recommended Practice (ARP) is an industrial collaboration with regulatory bodies like the European Aviation Safety Agency (EASA) and the Federal Aviation Administration (FAA) to determine the worst-case credible thermal runaway (TR) condition (energy released and maximum temperature) for the design of an aviation large propulsion battery system to quantitatively verify TR in lieu of battery level RTCA DO-311A testing with protections disabled. The ARP considers the three stages of TR within a cell and defines the two critical temperatures for a specific cell design. These temperatures are key to understanding the layers of monitoring necessary to determine the severity of a TR event. Different trigger methods can be used to quantify the heating characteristics and resultant energy profile releases as a function of time.

This specification establishes requirements for a corrosion-removing compound in the form of a liquid concentrate.

This specification covers requirements for silver deposited on metal parts with a nickel strike between the basis metal and the silver deposit.

This document provides guidance for a means of showing compliance with regulations for protection against lightning direct effects for aircraft of conventional design, as well as for those involving advanced composite structures or other new technologies. This guidance also applies to those aspects of aircraft systems and components not addressed in the regulations covering the protection of electrical/electronic systems (for example, FAR/JAR xx.1316) or fuel systems (for example, xx.954). The guidance provided in this document applies to initial designs as well as modifications.

This document covers metric studs made from a corrosion and heat resistant, age hardenable iron base alloy of the type identified under the Unified Numbering System as UNS S66286. The following specification designations and their properties are covered:

SAE J115 specifies the relevant ISO standards for application to safety labels for use on off-road work machines as defined in SAE J1116.

This specification covers the requirements for ion vapor deposited (IVD) aluminum on steel, titanium, and aluminum alloys.

This specification establishes the engineering requirements for producing an acid-type, anodic coating on magnesium alloys and the properties of the coating.

This specification covers a high strength fluorosilicone (FVMQ) elastomer that can be used to manufacture product in the form of sheet, strip, tubing, extrusions, and molded shapes. This specification should not be used for molded rings, compression seals, molded O-ring cord, and molded in place gaskets for aeronautical and aerospace applications.

This guide is intended to promote safe designs, operations and maintenance on aircraft and ground support oxygen systems. This is also a summary of some work by the ASTM G 4 Committee related to oxygen fire investigations and design concerns to reduce the risk of an oxygen fire. There have been many recent technological advances and additional test data is available for evaluating and controlling combustion hazards in oxygen equipment. Standards that use this new information are rapidly evolving. A guide is needed to assist organizations and persons not completely familiar with this process to provide oxygen systems with minimum risks of combustion. This guide does not necessarily address all the detailed issues and provide all data that will be needed. For a complete analysis, supplemental publications need to be consulted. This guide does discuss the basics of oxygen systems fire hazards. The hazard analysis process is discussed and a simple example to explain this process.

This document covers bolts and screws made from a corrosion and heat resistant, precipitation hardenable, iron base alloy of the type identified under the Unified Numbering System as UNS S66286.

This foundation specification (AMS1424S) and its associated category specifications (AMS1424/1 and AMS1424/2) cover a deicing/anti-icing material in the form of a fluid.

This specification covers a butyl (IIR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.

This specification covers an aluminum-beryllium alloy in the form of bars, rods, tubing, and shapes consolidated from powder by extrusion.

These recommendations are to aid the international air transport industry by identifying a standard, minimum amount of safety instructions and procedures that should be provided in the PSIS. Aircraft operators are encouraged to customize the PSIS to their own operations. This document also provides recommendations for: a Passenger safety information briefings and associated materials, b Demonstration emergency equipment, c Ensuring passenger suitability for those seated in exit seats, d The standardization of safety briefings for passengers seated at exits who may be responsible for opening exits on transport aircraft during an emergency, and e A standardized protective brace position to reduce the severity of injury during severe turbulence, rapid deceleration, or a sudden impact.

This revision will make the following updates: - Align zone 3 direct attachment guidance with ARP5414. This will be accomplished by not making any claims about when zone 3 direct attachment is required, and allow that guidance to reside solely in ARP5414. - Correct the erroneous inclusion of component D with zone 1C.

This specification covers requirements for producing brazed joints in parts fabricated from corrosion- and heat-resistant steels, carbon or low-alloy steels, or copper alloys, and the properties of such joints.

This specification covers a water-soluble, oil-dispersing cleaner in the form of a liquid.

This specification covers a cleaner in the form of a liquid.
