This SAE Recommended Practice is intended to serve as a reference for the amount of torque that a Power Take-Off can induce on the transmission mounting pad. This document will apply to six-bolt, eight-bolt, and rear mounted power take-offs.
This document provides test methods for evaluating the maximum power of electrified vehicle powertrain systems by direct measurement at the drive wheel hubs or axles. Additional tests are included specifically for PHEVs to measure electric-only propulsion power and for HEVs to measure electric power assist and regenerative braking. The testing requires either a chassis or hub dynamometer for all driven wheels. Results are processed to provide fair and consistent comparisons of power capabilities among different designs of electrified powertrains. Tests can also be performed on conventional vehicles if precise comparisons to electrified vehicles are desired.
This SAE Recommended Practice provides the methods of measurements for electrical and photometric characteristics of LED packages. It provides procedures, requirements, and guidelines for the methods of the measurement of luminous flux and color maintenance of LED devices (packages, arrays, and modules) for ground vehicle lighting applications.
To define test cases for the OBD-II interface on external test equipment (such as an OBD-II Scan Tool, Inspection/Maintenance Tester, etc.) which can be used to verify compliance with the applicable standards such as SAE J1978 and SAE J1979 for Passenger Cars, Light-Duty Trucks, and Medium-Duty Vehicles and Engines (OBD II).
This SAE Recommended Practice defines a procedure for the use of computer generated saturation curves to determine peening intensity. Calculation of intensity within a tolerance band for each data set in Table 1 one is required for compliance with this practice.
The heating value or heat of combustion is a measure of the energy available from the fuel. The fraction or percentage of the heat of combustion that is converted to useful work is a measure of the thermal efficiency of an engine. Thus, a knowledge of the heat of combustion of the fuel is basic to the engineering of automotive engines. This SAE Information Report provides information on the standardized procedures for determining the heat of combustion of fuels that may be used for automotive engines. The changes to SAE J1498 include: SAE Publications - Added SAE Paper 2010-01-1517 Other Publications and Sections 5, 9, and 10 - Updated ASTM alphanumeric designations and titles. Section 10 - Added discussion of a method to calculate net heating value for gasoline-ethanol blends using ASTM D3338.
This SAE Recommended Practice describes a test method for determining the vertical force and deflection properties of a non-rolling tire and the associated contact patch length and width. The method applies to any tire so long as the equipment is properly scaled to conduct the measurements for the intended test tire. The data are suitable for use in determining parameters for road load models and for comparative evaluations of the measured properties in research and development. NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular pavements. Within the context of this Recommended Practice, forces applied to the pavement are not considered.
This SAE Recommended Practice describes application of two closely related test procedures, which together determine the linear range longitudinal and lateral stiffnesses of a statically loaded non-rotating tire. The procedures apply to any tire so long as the equipment is properly sized to correctly conduct the measurements for the intended test tire. The data are suitable for use in determining parameters for road load models and for comparative evaluations of the measured properties in research and development. NOTE: Herein, road load models are models for predicting forces applied to the vehicle spindles during operation over irregular pavements. Within the context of this document, forces applied to the pavement are not considered.
This SAE Standard outlines the engine oil performance categories and classifications developed through the efforts of the Alliance of Automobile Manufacturers (Alliance), American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), the Engine Manufacturers Association (EMA), International Lubricant Specification Advisory Committee (ILSAC), and SAE. The verbal descriptions by API and ASTM, along with prescribed test methods and limits are shown for active categories in Table 1 and obsolete categories in Table A1. Appendix A is a historical documentation of the obsolete categories. For purposes of this document, active categories are defined as those (a) for which the required test equipment and test support materials, including reference engine oils and reference fuels, are readily available, (b) for which ASTM or the test developer monitors precision for all tests, and (c) which are currently available for licensing by API EOLCS.
The following listed definitions are intended to establish terminology and criteria for describing the various kinds of automotive transmissions. A specific arrangement may be described by a combination of several of these definitions.
This SAE Recommended Practice is prepared as a guideline to improve and maintain the quality of remanufactured automotive products. Installation of remanufactured or rebuilt products is often an economical way to repair a vehicle even though they may not fully be equivalent to original equipment parts. Before processing any part, a remanufacturer should determine if the original design and present condition of the core are suitable for remanufacturing, so as to provide durable operation of the part as well as acceptable performance when installed in a vehicle. The remanufacturer should also carefully consider the safety aspects of the product and any recommendations of the original manufacturer related to remanufacturing or rebuilding their product.
ISO 7745 shall be used for providing detailing, operational characteristics, advantages, disadvantages, and factors affecting the choice to be made among fire-resistant fluids. HFAE, HFC, HFDR, HFDU and HETG oils are covered in this specification. HFAS, HFB and HFDS fluids are not addressed.
This SAE standard applies to refrigerant identification equipment to be used for identifying an acceptable level of R-1234yf purity in a refrigerant tank or vehicle MAC system labeled as containing R-1234yf, and not misidentify other refrigerants, per 5.7.
