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 low-alloy steel in the form of bars, forgings, mechanical tubing, and forging or tubing stock.
This supplement forms a part of SAE Aerospace Specification AS85421. It shall be used to identify fitting standards citing this procurement specification.
This SAE Recommended Practice incorporates a track-based test procedure that produces a representative value for vehicle top speed when operating on a level paved road with a fully charged battery.
This standard defines a color index system used by, but not limited to, Government activities in a format suitable for color identification, color selection, color matching, and quality control inspection. It also describes the designation and use of color media that is available to conduct these activities. Use of the color index referenced in this standard is intended to promote standardization and consistency in the color of items produced for Government use. Color media is described as follows: Color Chip Representation, Fan Deck: Suitable for color identification and selection. Color Chip Representation, Color Book: Suitable for color identification and selection. Precise Color Matching, Individual Color Chips: Suitable for color matching and quality control inspection purposes. Precise Color Matching, Set of Color Chips: Suitable for color matching and quality control inspection purposes.
This AIR provides a detailed example of the aircraft and systems development for a function of a hypothetical S18 aircraft. In order to present a clear picture, an aircraft function was broken down into a single system. A function was chosen which had sufficient complexity to allow use of all the methodologies, yet was simple enough to present a clear picture of the flow through the process. This function/system was analyzed using the methods and tools described in ARP4754A/ED-79A. The aircraft level function is “Decelerate Aircraft On Ground” and the system is the braking system. The interaction of the braking system functions with the aircraft are identified with the relative importance based on implied aircraft interactions and system availabilities at the aircraft level. This example does not include validation and verification of the aircraft level hazards and interactions with the braking system. However, the principles used at the braking system level can be applied at the
This SAE Recommended Practice provides a procedure for measuring quantitatively the physical characteristics of linear impactors that are believed to effect impact test accuracy, repeatability, and reproducibility. Suggested values and tolerance are also provided for specific applications of linear impactor testing (i.e., ejection mitigation tests, head form impact tests, body block tests). Two functional groups of linear impactors are considered: those whose function is related primarily to displacement, and those related to measuring acceleration or force.
This SAE Standard serves as a guide for testing procedures of automotive 12 V storage batteries. The information contained herein was originally developed based on traditional ICE operation but can be more broadly applicable to other vehicle architectures. Although the test procedures contained herein are written from the standpoint of a 12 V nominal battery, they can be scaled for batteries with different nominal voltages.
This SAE Recommended Practice applies to excavators and backhoe loaders, as defined in ISO 6165.
The scope of this SAE Information Report is to supply the user with sufficient information so that he may decide whether liquid penetrant test methods apply to his particular inspection problem. Detailed technical information can be obtained by referring to Section 2.
This SAE Standard applies to all forestry machines exposed to the hazard of objects penetrating the front of the operator station (other than the roof). This would include:
This document applies to the development of Plans for integrating and managing electronic components in equipment for the military and commercial aerospace markets, as well as other ADHP markets that wish to use this document. Examples of electronic components described in this document include resistors, capacitors, diodes, integrated circuits, hybrids, application specific integrated circuits, wound components, and relays. It is critical for the Plan owner to review and understand the design, materials, configuration control, and qualification methods of all “as-received” electronic components and their capabilities with respect to the application; and to identify risks and, where necessary, take additional action to mitigate the risks. The technical requirements are in Section 3 of this standard and the administrative requirements are in Section 4.
Communicate the process of accurately measuring sound power levels of positive displacement hydraulic pumps commonly used in ground vehicle steering systems. This recommended practice defines the pump mounting (pulley, belt tension, isolation), operating conditions (fluid, speed, temperature, pressure), room acoustics, instrumentation, noise measurement technique and data acquisition setup to be used. Included are recommendations for test sample size, and format for data presentation/reporting.
This SAE Recommended Practice was developed primarily for passenger car and truck applications but may be used in marine, industrial, and similar applications.
This SAE Aerospace Recommended Practice (ARP) establishes the overall component and system function guidelines and minimum performance levels for a TPMS. These guidelines include, but are not limited to: Design recommendations for system components, which: Monitor tire inflation Are located in/on the tire/wheel assembly, landing gear axle, and/or aircraft avionics compartment Recommended performance and safety guidelines for a TPMS.
This SAE Standard provides a means for specifying or describing the pertinent properties of fiberboards for automotive applications. The materials normally specified by this standard are defined in SAE J947. The test methods commonly used for fiberboards are defined in SAE J315.
This specification covers a premium aircraft-quality maraging steel in the form of bars and forgings, 0.50 to 8.00 inches (12.7 to 203.2 mm) in nominal diameter or least distance between parallel sides, and forging stock of any size.
