This SAE Aerospace Information Report (AIR) addresses procedures applicable to quantifying the emission of nonvolatile particulate matter at the exit plane of aircraft gas turbine engines. While both volatile and nonvolatile particulate matter (PM) are present in aircraft gas turbine exhaust, the methods used to measure nonvolatile particles are farther advanced and are addressed here. Existing PM measurement regulations employ the SAE Smoke Number measurement (Reference 2.1.1), a stained filter technique used in evaluating visible emissions. The environmental and human health issues associated with submicronic PM emissions require more detailed measurement of the mass, size, and quantity of these particle emissions. Responding to regulatory agency requests, this AIR describes measurement techniques that are well developed and could be applied to the measurement of aircraft engine particulate matter. The techniques discussed here are considered relevant for measuring particle
This SAE Aerospace Standard (AS) covers the requirements for threaded lubrication fittings, straights and elbows, to be used for admitting and retaining lubricants supplied by pressure lubricating equipment
This specification establishes requirements for chemically expanded, flexible, electrical insulating sleeving that shrinks to a predetermined size upon solvent evaporation
This SAE Aerospace Standard (AS) defines the requirements for a lightweight polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in high temperature, 400 °F, high pressure, 3000 psi, aircraft hydraulic systems, also for use in pneumatic systems which allow some gaseous diffusion through the PTFE wall
This SAE Aerospace Recommended Practice (ARP) specifies the methods, equipment, and materials to be used in the installation, mounting, and testing of receptacle connectors used in pressure differential applications requiring an effective connector seal
This Minimum Performance Document defines the testing required for wheels, brakes, and wheel and brake assemblies to be used on civil aircraft certified under 14 Code of Federal Regulations (CFR) Part 23, 27, and 29. Compliance with this document is recommended to assure that the equipment supplied will meet the intended design function when installed on aircraft. Compliance with this document does not constitute authorization for installation on an aircraft. The combined recommendations of this document provide an acceptable practice, but not the only practice, for obtaining authorization to apply TSO markings on the equipment
This SAE Standard covers empty cartridges, plungers, cartridge assemblies, and nozzles which are used to package, store, and dispense single or multiple component sealants, adhesives, and other similar materials. This document defines the size, shape, composition, and function of the plastic molded cartridges, plungers, and cartridge assemblies. This document is not intended as a detailed manufacturing document
This SAE Aerospace Information Report (AIR) provides a general description of methods for hardness testing of O-rings including factors which affect precision and comparison of results with those obtained in standard tests
The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize locations of aircraft ground service connections to accommodate the trend toward fixed systems, which use the passenger boarding bridge and/or underground “pop-up” or pit systems as a source of utilities. It must be recognized that, in standardizing the locations of the aircraft service connections, they must continue to be served efficiently in those instances where mobile ground support equipment is used. There is an ever increasing number of fixed installations for aircraft servicing. The objectives to be met by standardizing the locations of the aircraft service connections are the following
The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide recommended test fluids for testing of electrical components used on aircraft exterior or for ground support near aircraft. These fluids were selected based on a consolidation of test fluids used by military and commercial sources and on review of national and international component specifications. These recommendations are general guidelines. Safety factors for any unusual testing applications or operating conditions should be given special consideration by the designer. The test fluids provided are intended to be recommendations and are not intended to limit or supersede those recommended by aircraft or ground support equipment manufacturers
This Aerospace Recommended Practice includes the following areas: basis for system requirements; selection of materials coupled with hazards and safety; configuration of design; system operation; and evaluation testing
This SAE Aerospace Recommended Practice (ARP) provides the industry agreed methods to keep the center of gravity (C.G.) location of loaded air cargo Unit Load Devices (ULDs) within the maximum horizontal and vertical limits allowed by their airworthiness approval
The purpose of this Aerospace Recommended Practice (ARP) is to provide the sample selection criteria and endurance time test procedures for SAE Type I aircraft deicing/anti-icing fluids, required for the generation of endurance time data of acceptable quality for review by the SAE G-12 Holdover Time Committee. A significant body of previous research and testing has indicated that all Type I fluids formulated with conventional glycols, as defined in 3.1.1 of AMS1424, perform in a similar manner from an endurance time perspective. This applies to Type I deicing/anti-icing fluids formulated with propylene glycol, ethylene glycol, and diethylene glycol only. As a result, Type I deicing/anti-icing fluids containing these glycol bases no longer require testing for endurance times. The methods described in this ARP shall be employed, however, if endurance time testing of a conventional glycol-based Type I deicing/anti-icing fluid is desired or requested by a fluid manufacturer, operator or
This SAE Aerospace Information Report (AIR) documents general technical data associated with many of the wheels used in the Air Force
This SAE Aerospace Recommended Practice (ARP) presents a procedure for evaluating cleaning methods with respect to contaminant removal and element degradation particularly for metallic filter elements. A procedure for checking durability of cleaning equipment and a referee cleaning method are also included. It is applicable only to the evaluation of cleaning methods proposed for removal of service dirt and not for built-in dirt, liquid oxygen (LOX) cleaning, etc. Supporting information for use with the ARP is also included
This document provides information on contamination and its effects on brakes having carbon-carbon composite friction materials (carbon). Carbon is hygroscopic and porous, and therefore readily absorbs liquids and contaminants. Some of the contaminants can impact intended performance of the brake. This document is intended to raise awareness of the effects of carbon brake contamination and provide information on industry practices for its prevention. Although not addressed in this report, contaminants can cause problems with other landing system components including tires
This SAE Aerospace Standard (AS) covers helical coil locking screw thread inserts made from formed wire in which the inner surface of the coil, after assembly, provides threads of standard Unified 60° form as specified on the assembly drawing. This document also covers the performance requirements of the locking feature of the insert which will retain Unified ANSI B1.1 (UN Profile) or AS8879 (UNJ Profile) external threaded parts
