Load Deflection Testing of Urethane Foams for Automotive Seating

1994-01-01
HISTORICAL
J815_199401
Cellular foam products have been traditionally checked for load deflection by determining the load required to effect a 25% deflection. In seating, on the other hand, the interest is in determining how thick the padding is under the average passenger load (a measurement of padding left for 'ride' and seated height), a second measurement to give an indication of initial softness, and a final figure to indicate resiliency. To most easily fulfill these requirements, load deflection on flexible urethane foams for automotive seating is determined here by measuring the thickness of the pad under fixed loads of 1 lb, 25 lb, and 50 lb on a 50 sq in. circular indentor foot.

HISTORICAL
J2012_199401
This SAE Recommended Practice is applicable to all light-duty and medium-duty passenger vehicles and trucks with feedback fuel control system. Specific applications of this document include diagnostic, servce and repair manuals, repair databases, and off-board readout devices. This document focuses on a diagnostic code format and code messages for automotive electronic control systems. The use and appropriate updating of this document is strongly encouraged; however, this document does not prohibit the use of additional codes for additional diagnostics.

Electronic Data Interchange Between Microcomputer Systems in Heavy-Duty Vehicle Applications

1994-01-01
HISTORICAL
J1587_199401
This SAE Recommended Practice defines a document for the format of messages and data that is of general value to modules on the data communications link. Included are field descriptions, size, scale, internal data representation, and position within a message. This document also describes guidelines for the frequency of and circumstances in which messages are transmitted. In order to promote compatibility among all aspects of electronic data used in heavy-duty applications, it is the intention of the SAE Truck and Bus Low Speed Communications Network Subcommittee (formerly Data Format Subcommittee) (in conjunction with other industry groups) to develop recommended message formats for: a. Vehicle and Component Information-This includes all information that pertains to the operation of the vehicle and its components (such as performance, maintenance, and diagnostic data). b. Routing and Scheduling Information-Information related to the planned or actual route of the vehicle.

Coding Systems for Identification of Fluid Conductors and Connectors *HS-150/2000*

1993-12-16
HISTORICAL
J846_199312
This coding system is intended to provide a convenient means of identifying the various tube, pipe, and hose fittings and of transmitting technical or engineering information relating to them wherever drawings or other pictorial media may not be readily available. The code has been kept flexible to permit expansion to cover new fitting categories or styles and, if the need develops, the inclusion of materials. The system is also compatible with automatic data processing equipment. It is not intended that this code should supersede established systems or means of identification. However, because the SAE code for automotive flare fittings shown in SAE J512 is also applicable to corresponding refrigeration fittings in SAE J513, both an SAE code and the existing code ANSI B70.1, are included throughout SAE J513. Therefore, it should be the prerogative of the user to apply that code which best satisfies his requirements.

HISTORICAL
J1783_199312
This SAE Hydrospace Recommended Practice provides the designer with guidance for the selection of directional control valves for use in the hydraulic systems of surface ships and submersibles. This guidance includes use of standard valves and interfaces, minimum envelopes which should be reserved to permit interchangeability, and environmental considerations.

HISTORICAL
J619_199312
This SAE Recommended Practice defines flywheel configuration to promote standardization of flywheels for dry spring-loaded clutches. Clutches to fit flywheels with configurations per this recommended practice may not be commercially available. Availability should be ascertained prior to flywheel design (see Figure 1 and Table 1).

Fuel and Oil Hoses

1993-12-01
HISTORICAL
J30_199312
This SAE standard covers fuel, oil, or emission hose for use in coupled and uncoupled applications, for use with gasoline, oil, diesel fuel, lubrication oil, or the vapors present in either the fuel system or in the crankcase of internal combustion engines in mobile or stationary applications. This standard covers the hose portion only. If assembly / coupling is required, that is to be agreed to between the customer and assembler, along with the specific requirements.

VOLTAGES FOR DIESEL ELECTRICAL SYSTEMS

1993-11-23
CURRENT
J539_199311
This SAE Recommended Practice is intended to apply to lamps, batteries, heaters, radios, and similar equipment for operation with mobile or automotive diesel engines. Twenty-four V systems have long been used for heavy-duty services because 24 V permit operating 12 V systems in series-parallel. Thirty-two V systems have been used for marine, railroad-car lighting, and other uses. Generators, storage batteries, starting motors, lighting, and auxiliary electrical equipment shall be for nominal system ratings of 12, 24, or 32 V as determined by the power requirements of the application. It is recommended that no intermediate voltages be considered. The combination of a 24 V starting motor and two 12 V batteries connected in series for cranking is considered practical where it can be adapted to the installation.

Cantilevered Boom Crane Structures-Method of Test

1993-11-18
HISTORICAL
J1063_199311
This SAE Standard applies to mobile, construction-type lifting cranes of the cantilever boom type. Questions and comments regarding application or interpretation of the provisions in this test method should be referred to the originating SAE Committee. The purpose of this test method is to provide a systematic, nondestructive procedure for determining the stresses induced in cantilevered boom crane structures under specified conditions of static loading through use of resistance-type electric strain gages, and to specify appropriate stress levels for specified loading conditions. Further, a 25% overload test is included to prove the overall structural integrity of the structure.

BODY CORROSION—A COMPREHENSIVE INTRODUCTION

1993-11-01
HISTORICAL
J1617_199311
The mechanism of automotive body corrosion is scientific, based on established laws of chemistry and physics. Yet there are many opinions related to the cause of body corrosion, not always based on scientific axioms. The purpose of this SAE Information Report is to present a basic understanding of the types of body corrosion, the factors that contribute to body corrosion, the testing procedures, evaluation of corrosion performance, and glossary of related terms.

High-Strength, Hot-Rolled Steel Bars

1993-11-01
HISTORICAL
J1442_199311
This SAE Recommended Practice covers two levels of high strength structural low-alloy steel bars having minimum Yield Points of 345 MPa (50 ksi) and 450 MPa (65 ksi). The two strength levels are 345 and 450 MPa or 50 and 65 ksi minimum yield point. Different chemical compositions are used to achieve the specified mechanical properties. In some cases there are significant differences in chemical composition for the same strength level, depending on the fabricating requirements. It should be noted that although the mechanical properties for a steel grade sourced from different suppliers may be the same, the chemical composition may vary significantly. The fabricator should be aware that certain compositional differences may effect the forming, welding, and/or service requirements of the material. It is therefore recommended that the fabricator consult with the producer to understand the effect of chemical composition.
