This SAE Recommended Practice establishes the minimum interface compatibility requirements for electric vehicle (EV) inductively coupled charging for North America. This part of the specification is applicable to manually connected inductive charging for Levels 1 and 2 power transfer. Requirements for Level 3 compatibility are contained in Appendix B. Recommended software interface messaging requirements are contained in Appendix A. This type of inductively coupled charging is generally intended for transferring power at frequencies significantly higher than power line frequencies. This part of the specification is not applicable to inductive coupling schemes that employ automatic connection methods or that are intended for transferring power at power line frequencies.
This SAE Standard defines the terminals that carry the electrical current developed in the main cranking circuit of the starting systems used in off-road machinery as described in SAE J1116. These systems normally use batteries as described in SAE J 537 and J930. The terminals addressed by this document are primarily used to correct batteries, cranking motors, solenoids, magnetic switches, and master disconnect switches with power cable assemblies. This document defines the performance requirements for power cable terminals used in the electrical starting system.
The methods presented in this SAE Recommended Practice apply to the controlled testing of low-temperature charge, air-cooled, heavy-duty diesel engines. This document encompasses the following main sections: a.) Definitions of pertinent parameters; b.) Vehicle testing to determine typical values for these parameters; c.) Description of the setup and operation of the test cell system; and d.) Validation testing of the test cell system. While not covered in this document, computer modeling of the vehicle engine cooler system is recognized as a valid tool to determine cooler system performance and could be utilized to supplement the testing described. However, adequate in-vehicle testing should be performed to validate the model before it is used for the purposes outlined. The procedure makes references to test cycles that are prescribed by the United States Environmental Protection Agency (US EPA) and are contained in the Code of Federal Regulations.
The practice described applies to textile and flexible plastic parts and materials used in automotive vehicles. Special care should be taken when high pile carpet samples are being evaluated. The intent of this SAE Recommended Practice is to specify procedures for the instrumental measurement of color differences brought about by the exposure of textile and flexible plastic automotive parts to various colorfastness tests. It may be used for the specification of limits of color differences which may be tolerated in a specific test.
This SAE Standard covers molded rubber boots used as end closures on drum-type wheel brake actuating cylinders to prevent the entrance of dirt and moisture, which could cause corrosion and otherwise impair wheel brake operation. The document includes performance tests of brake cylinder boots of both plain and insert types under specified conditions and does not include requirements relating to chemical composition, tensile strength, or elongation of the rubber compound. Further, it does not cover the strength of the adhesion of rubber to the insert material where an insert is used. The rubber material used in these boots is classified as suitable for operation in a temperature range of -40 to +120 °C ± 2 °C (-40 to + 248 °F ± 3.6 °F).
This SAE Standard covers motor vehicle brake fluids of the nonpetroleum type for use in the braking system of any motor vehicle such as a passenger car, truck, bus, or trailer. These fluids are not intended for use under arctic conditions. These fluids are designed for use in braking systems fitted with rubber cups and seals made from natural rubber (NR), styrene-butadiene rubber (SBR), or a terpolymer of ethylene, propylene, and a diene (EPDM).
This document supersedes SAE J1962 FEB1998, and is technically equivalent to ISO/DIS 15031-3:December 14, 2001. The SAE J1962 diagnostic connector consists of two mating connectors, the vehicle connector and the test equipment connector. This document: a. Defines the functional requirements for the vehicle connector. These functional requirements are separated into three principal areas: connector location/access, connector design, and connector terminal assigments; b. Defines the functional requirements for the external test equipment connector. These functional requirementsare separated into two principal areas: connector design and connector terminal assignements. The scope of this document does not include the needs of long-term retention, such as in-flight recorder type applications. To ensure long-term retention, additional steps outside of the scope of this document must be taken.
This SAE Standard covers low tension battery cable intended for use at a nominal system voltage of 50 V rms or less in surface vehicle electrical systems. The tests are intended to quality cables for normal applications with limited exposure to fluids and physical abuse.
This SAE Recommended Practice provides headlamp beam patter test points which incorporate elements of European, Asian, and U.S. photometric tables. Alternative means of aiming headlamps are included which are consistent with methods presently used in the United States and in Europe.
This SAE Recommended Practice defines the information contained in the header and data fields of non-diagnostic messages for automotive serial communications based on SAE J1850 Class B networks. This document describes and specifies the header fields, data fields, field sizes, scaling, representations, and data positions used within messages. The general structure of a SAE J1850 message frame without in-frame response is shown in Figure 1. The structure of a SAE J1850 message with in-frame response is shown in Figure 2. Figures 1 and 2 also show the scope of frame fields defined by this document for non-diagnostic messages. Refer to SAE J1979 for specifications of emissions related diagnostic message header and data fields. Refer to SAE J2190 for the definition of other diagnostic data fields. The description of the network interface hardware, basic protocol definition, the electrical specifications, and the CRC byte are given in SAE J1850.
This SAE Standard defines requirements for equipment/supplies to be used in measuring shot peening intensity. Guidelines for the use of these articles (test strip, holding fixture, and gage) are also included.
This SAE Standard describes a laboratory test procedure for comparatively evaluating the durability and fatigue life qualities of a complete seat cushion by submitting the seating surface of the cushion to repetitive compressive and rotational loading with a simulated human buttocks. This document provides a uniform method of dynamically testing the durability of seat cushions on a comparative basis.
This SAE Recommended Practice describes a procedure for measuring gaseous hydrogen emissions from the aqueous battery system of a battery-powered passenger car or light truck. The purpose of this procedure is to determine what concentrations of hydrogen gas an electric vehicle together with its charger will generate while being charged in a residential garage. Gaseous emissions are measured during a sequence of vehicle tests and laboratory tests that simulate normal and abnormal conditions during operational use. The results of this test may be used to determine whether or not forced air ventilation is required when a particular electric vehicle and its associated battery and charging system are used in a residential garage.
This SAE Recommended Practice was prepared by the Motor Vehicle Brake Fluids Subcommittee of the SAE Hydraulic Brake Systems Actuating Committee to provide engineers, designers, and manufacturers of motor vehicles with a set of minimum performance standards in order to assess the suitability of silicone and other low water tolerant type brake fluids (LWTF) for use in motor vehicle brake systems. These fluids are designed for use in braking systems fitted with rubber cups and seals made from natural rubber (NR), styrene-butadiene rubber (SBR), or a terpolymer of ethylene, propylene, and a diene (EPDM). In the development of the recommended requirements and test procedures contained herein, it is concluded that the LWTFs must be functionally compatible with existing motor vehicle brake fluids conforming to SAE J1703 and with braking systems designed for such fluids. To utilize LWTFs to the fullest advantage, they should not be mixed with other brake fluids.
