This SAE Aerospace Recommended Practice (ARP) recommends a methodology to be used for the design, analysis and test evaluation of modern helicopter gas turbine propulsion system stability and transient response characteristics. This methodology utilizes the computational power of modern digital computers to more thoroughly analyze, simulate and bench-test the helicopter engine/rotor system speed control loop over the flight envelope. This up-front work results in significantly less effort expended during flight test and delivers a more effective system into service. The methodology presented herein is recommended for modern digital electronic propulsion control systems and also for traditional analog and hydromechanical systems.
This SAE Standard establishes a test method and a definition for disclosing the performance of suction/blower fans when applied to self-propelled sweepers that solely use a pneumatic conveyance means for the collection and transfer of “sweepings” into a collection hopper.

This SAE Surface Vehicle Technical Information Report, SAE J2836/4, establishes diagnostic use cases between plug-in electric vehicles (PEV) and the electric vehicle supply equipment (EVSE). As PEVs are deployed and include both plug-in hybrid electric (PHEV) and battery electric (BEV) vehicle variations, failures of the charging session between the EVSE and PEV may include diagnostics particular to the vehicle variations. This document describes the general information required for diagnostics and SAE J2847/4 will include the detail messages to provide accurate information to the customer and/or service personnel to identify the source of the issue and assist in resolution. Existing vehicle diagnostics can also be added and included during this charging session regarding issues that have occurred or are imminent to the EVSE or PEV, to assist in resolution of these items.
This SAE Standard covers the mechanical and material requirements for three grades of steel nuts suitable for use in automotive and related engineering applications, in sizes 1/4 to 1-1/2 inches, inclusive, and with dimensions conforming with the requirements of the latest issue of SAE J482 or ASME B18.2.2, except for machine screw nuts which are not covered in this standard. This document does not include limits for surface discontinuities. Where usage requires such control, limits may be specified separately. For sizes 1/4 through 1 inch, this may be done by the statement: “Surface discontinuities shall not exceed the limits specified in ASTM F812/F812M.”
This SAE Recommended Practice provides uniform laboratory procedures for biaxial fatigue testing of wheels intended for normal highway use and temporary use on passenger car vehicles and light trucks and minimum cycle requirement for ferrous wheels for ballasted passenger car applications. The appendices provide scalable load files that are applicable to ballasted passenger cars and ballasted light trucks. A load file for unballasted passenger cars will be added to this document.
SAE J2534-1_0500 defines the pass-thru interface requirements for the reprogramming of emission related control modules. The SAE J2534-2/X_0500 document set adds extensions to the SAE J2534-1_0500 API (version 05.00) specification so that the API can be used for features not covered in the SAE J2534-1_0500 specification. Together, these features provide a comprehensive framework for a common standard, to protect the software investment of the vehicle OEMs and scan tool manufacturers. There is no required for an SAE J2534-2/X_0500 pass-thru interface to be fully compliant with SAE J2534-1_0500. SAE J2534-2/X_0500 interfaces can implement some or all of the features specified in the SAE J2534-2/X_0500 document set. This document must be used in conjunction with the SAE J2534-2/RE_0500 document.
This recommended practice provides guidance on vehicle Cybersecurity and was created based off of, and expanded on from, existing practices which are being implemented or reported in industry, government and conference papers. The best practices are intended to be flexible, pragmatic, and adaptable in their further application to the vehicle industry as well as to other cyber-physical vehicle systems (e.g., commercial and military vehicles, trucks, busses). Other proprietary Cybersecurity development processes and standards may have been established to support a specific manufacturer’s development processes, and may not be comprehensively represented in this document, however, information contained in this document may help refine existing in-house processes, methods, etc. This recommended practice establishes a set of high-level guiding principles for Cybersecurity as it relates to cyber-physical vehicle systems. This includes: Defining a complete lifecycle process framework that can
The following schematic diagrams reflect various methods of illustrating automotive transmission arrangements. These have been developed to facilitate a clear understanding of the functional interrelations of the gearing, clutches, hydrodynamic drive unit, and other transmission components. Two variations of transmission diagrams are used: in neutral (clutches not applied) and in gear. For illustrative purposes, some typical transmissions are shown.
