This SAE Aerospace Standard (AS) defines the requirements for polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assemblies suitable for use in aerospace hydraulic, fuel, and lubricating oil systems at temperatures between -67 and 450 °F for Class I assemblies, -67 and 275 °F for Class II assemblies, and at nominal pressures up to 1500 psi. The hose assemblies are also suitable for use within the same temperature and pressure limitations in aerospace pneumatic systems where some gaseous diffusion through the wall of the PTFE liner can be tolerated. The use of these hose assemblies in pneumatic storage systems is not recommended. In addition, installations in which the limits specified herein are exceeded, or in which the application is not covered specifically by this standard (for example, oxygen), shall be subject to the approval of the procuring activity.
This SAE Standard provides general and dimensional specifications for beaded ends and hose fittings. These connections are intended for general applications in low-pressure automotive and hydraulic systems on automotive, industrial, and commercial products. The fittings shown are designed to be used with hoses that are intended to be retained by hose clamps. It is recommended that where step sizes or additional types of fittings are required they be designed to conform with the specifications of this document insofar as they may apply. The following general specifications shall supplement the dimensional data contained in the tables with respect to all unspecified detail.
The intent of this specification is for the procurement of carbon fiber and fiberglass epoxy prepreg products with 350 °F (177 °C) cure for aerospace applications; therefore, no qualification or equivalency threshold values are provided. Users that intend to conduct a new material qualification or equivalency program must refer to the production quality assurance section (see 4.3) of this base specification, AMS6891.
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 document provides a recommended electrical performance testing guideline for LIBM, which makes up an xEV (Battery Electric Vehicles and Hybrid Electric Vehicles) battery pack system. This testing guideline may also be used for other applications, such as stationary, vessel, and aircraft. However, using the guideline for other applications should be determined by the users of this document. Users of this document may also be interested in conducting tests on battery cells and/or battery packs. To avoid conducting potentially redundant tests between cells, modules, and packs, this document does not specify which tests need to be conducted. Determination of which tests need to be conducted is at the user’s discretion and should be based on individual module applications. Rather than specifying which tests need to be conducted, this document describes how each test is to be conducted. This document provides a matrix of tests that can be selectively picked for the application
This document is a result of the desire for interoperability of modules on a Pi-Bus. This standard is a stand alone document that used the Very High Speed Integrated Circuit (VHSIC) Phase 2, Interoperability Standard Pi-Bus Specification 2.2, as a starting point.
This SAE Standard was developed to provide a method for indicating the direction of engine rotation and numbering of engine cylinders. The document is intended for use in designing new engines to eliminate the differences which presently exist in industry.
This specification covers a corrosion resistant steel in the form of wire type identified under the Unified Numbering System as UNS S30500.
This specification covers a fiberglass reinforced silicone rubber in the form of sheet, strip, and molded parts.
This part of SAE J514 covers general and dimensional specifications for NPTF pipe adapters and 30 degree NPSM adapter unions. These fittings are intended for general application in hydraulic systems on industrial equipment and commercial products. These fittings are capable of providing leak-proof, full-flow connections in hydraulic systems operating at working pressures as specified in Table 6. Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, the values shown in Table 6 should not be construed as a guaranteed minimum. For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting manufacturer to assure that performance levels will be safe and satisfactory.
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, and mechanical tubing 225 square inches (1452 cm2) and under in cross-sectional area and forging stock of any size.
This SAE Information Report prescribes dummies, procedures, and configurations that can be used for investigating the interactions that might occur between a deploying airbag and a child restrained by a child restraint system (CRS). During the inflation process, airbags generate a considerable amount of kinetic energy which can result in substantial forces being applied to a child who is restrained in a CRS in the front seat of a vehicle. Field data collected by the special crash investigation team of the National Highway Traffic Safety Administration (NHTSA) indicate that fatal forces can be developed. In response to these field data, NHTSA added a series of airbag/child interaction tests and limits to the Code of Federal Regulations (CFR 571.208) that deal with occupant protection, commonly known as Federal Motor Vehicle Safety Standards (FMVSS 208). The bases for NHTSA tests are the various test procedures that were developed by the International Standards Organization (ISO) and the
The SAE International task force on headlamp mounting height has considered the ramifications of reducing the maximum mounting height of headlamps on highway vehicles. The task force has concluded that it is in the best interest of the driving public to make a substantial reduction in the recommended maximum height at which headlamps, particularly low-beam headlamps, may be mounted. Heights as low as 36 to 40 in (90 to 100 cm) have been considered. New tractor vehicles are in fact being designed with headlamps mounted in this range. Further recommendations were withheld in anticipation of tests to demonstrate the effect of mounting height on the legibility of certain overhead signs.
This SAE Recommended Practice defines test methods and general requirements at all phases of development, production, and field analysis of electrical terminals (including sense pins), connectors, and components that constitute the jump-start connection for road vehicles having 42 V (nominal) electrical systems. The 42 V jump start connector is always remote from the vehicle battery and may take the form of an in-line or Header Connection, either of which is in an accessible location for attachment of a jumper cable from an assist vehicle or battery charger. WARNING—The Jump Start Connector requires environmental protection. This specification assumes that such protection is in place and remains effective for the life of the vehicle. The level of protection depends on the vehicle packaging environment and duty cycle. Appendix B of this document contains the physical specification for the Jump Start Connector.
This report investigates the use of single and multi-layer coatings on replaceable headlamp bulbs and how such coatings can affect the performance of bulbs in terms of light scattering, which can contribute to glare, and spectral separation in headlamps. Tests were developed to investigate the effects of absorptive and interference (multi-layer) coatings on bulbs, and on bulbs in headlamp systems. These tests provide validation for a proposed bulb color separation test, which establishes limits for spectral separation within the boundaries of SAE J578 white color requirements. The bulb color separation test provides a definitive selection criterion to identify bulbs that cause excessive light scatter (glare) and/or spectral separation in an optical system.
Document provides information on how military/commercial/gas turbine engine test cell/system users may benefit from this unique Coanda/Refraction concept.
This SAE Aerospace Standard (AS) provides general requirements for components that are used in commercial aircraft hydraulic systems. It also includes the 14 CFR Part 25/CS 25 regulations that apply to hydraulic components. It also provides information to be included in the Procurement Specification in Appendix A and a checklist for design reviews in Appendix B. It does not provide requirements for distribution elements such as hoses, pipe fittings and general tubing.
