This SAE Recommended Practice establishes uniform procedures for testing battery electric vehicles (BEVs) which are capable of being operated on public and private roads. The procedure applies only to vehicles using batteries as their sole source of power. It is the intent of this document to provide standard tests which will allow for the determination of energy consumption and range for light-duty vehicles (LDVs) based on the federal emission test procedure (FTP) using the urban dynamometer driving schedule (UDDS) and the highway fuel economy driving schedule (HFEDS) and provide a flexible testing methodology that is capable of accommodating additional test cycles as needed. Additionally, this SAE Recommended Practice provides five-cycle testing guidelines for vehicles performing supplementary testing on the US06, SC03, and cold FTP procedure. Realistic alternatives should be allowed for new technology.

SAE Aerospace Recommended Practice ARP1533 is a procedure for the analysis and evaluation of the measured composition of the exhaust gas from aircraft engines. Measurements of carbon monoxide, carbon dioxide, total hydrocarbon, and the oxides of nitrogen are used to deduce emission indices, fuel-air ratio, combustion efficiency, and exhaust gas thermodynamic properties. The emission indices (EI) are the parameters of critical interest to the engine developers and the atmospheric emissions regulatory agencies because they relate engine performance to environmental impact. While this procedure is intended to guide the analysis and evaluation of the emissions from aircraft gas turbine engines (burning conventional hydrocarbon based liquid fuels), the methodology may be applied to the analysis of the exhaust products of any hydrocarbon/air combustor.

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) provides the technical terms and nomenclature, together with their definitions and abbreviations/acronyms that are used in aerospace fluid power, actuation and control systems. NOTE: ARP490 and ARP4493 are sources for definitions specifically for electrohydraulic servovalves.

This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing.

This document covers the mechanisms from the power cylinder, which contribute to the mechanical friction of an internal combustion engine. It will not discuss in detail the influence of other engine components or engine driven accessories on friction.

This SAE standard describes alternator physical, performance, and application requirements for heavy-duty electrical charging systems for off-road work machines, including those defined in SAE J1116.

This SAE Aerospace Information Report (AIR) provides information regarding guidance when utilizing an SHM system for “airworthiness credits”. This document is applicable to civil fixed-wing aerospace airframe structural applications where stakeholders are seeking guidance on the approvals of structural health monitoring (SHM) technologies for aircraft health management applications. While this initial guidance is from the United States’ Federal Aviation Administration (FAA), Technical Innovation Policy Branch, other regulatory agencies may elect to add requirements as needed. Future revisions to this document could include the guidance from other regulatory agencies. This document does not teach how to design an SHM function, how to do a safety or risk analysis, prescribe hardware or software assurance levels, or answer the question “how much mitigation and evidence are enough.”

This Aerospace Information Report provides an overview of published data on different methods for designing electromechanical actuators with a very low probability of jam or disconnect.

This SAE Information Report provides a compendium of terms, definitions, abbreviations, and acronyms to enable common terminology for use in engineering reports, diagnostic tools, and publications related to active safety systems. This information report is a survey of terms related to calibration of active safety systems. The definitions offered are descriptions of inputs, outputs, and processes rather than technical specifications. Definitions for end-of-line procedures are not included.

This SAE Standard is intended for all sizes of fuel filters, so a variety of test stands may be required depending upon flow rate. The low contamination level, downstream clean-up filter, and short duration of the test ensure that the particle retention ability of the filter is measured in a single pass, as no appreciable loading or regression will occur.

This document delineates a recommended practice specifically designed for maintenance processes that involve more than one aviation maintenance stakeholders. These include (but are not limited to) Manufacturers, Operators, Maintenance Repair & Overhaul (MRO) organization and Part Providers. The framework's primary aim is to establish the necessary input for evaluating and accepting (or rejecting) implementing a prognostic model based on their impact from the unique perspective of each stakeholder. As a result, this document is best suited for maintenance processes involving Line-Replaceable Units (LRUs), as these system enter a repair process that involved multiple parties external to the airline operator. This document emphasizes economic efficiency in maintenance operations, targeting tasks that are currently managed on a corrective (or run-to-failure) basis outside of the Airline Maintenance Program.
