Serial Data Communications Between Microcomputer Systems in Heavy-Duty Vehicle Applications

1993-10-19
HISTORICAL
J1708_199310
This SAE Recommended Practice document defines a recommended practice for implementing a bidirectional, serial communication link among modules containing microcomputers. This document defines those parameters of the serial link that relate primarily to hardware and basic software compatibility such as interface requirements, system protocol, and message format. The actual data to be transmitted by particular modules, which is an important aspect of communications compatibility, is not specified in this document. These and other details of communications link implementation and use should be specified in the separate application documents referenced in Section 2. The purpose of this document is to define a general-purpose serial data communication link that may be utilized in heavy-duty vehicle applications. It is intended to serve as a guide toward standard practice to promote serial communication compatibility among microcomputer-based modules.

HISTORICAL
J1953_199310
This SAE Recommended Practice shall cover mechanical- and electrical-readjust stroke indicators for air-brake actuators. This device shall indicate the foundation brake(s) may require adjustment or service when inspected per vehicle manufacturer's procedures. A measurement shall be made to determine actual stroke measurement for any system not factor calibrated. Stroke indication accuracy of an air-brake actuator can be assured only when all of its components are supplied by the original brake actuator manufacturer. This document establishes design guidelines for air-brake actuator stroke indicators.

Minimum Requirements for Wheel-Slip Brake-Control System Malfunction Signals

1993-10-01
HISTORICAL
J1230_199310
It is recognized that a malfunction in any one of the specified areas can degrade intended performance, but that levels of malfunction or combinations thereof must be considered by the vehicle designer in determining the point at which a failure indication is warranted. Consequently, the minimum reaction recommended by this document consists of making available a malfunction signal. This SAE Recommended Practice establishes a uniform minimum set of functional areas to be monitored in the process of detecting malfunctions in discrete wheel-slip brake-control systems for motor vehicles, and establishes a minimum reaction to those detected malfunctions.

HISTORICAL
J254_199309
This SAE Recommended Practice establishes uniform laboratory techniques for the continuous and bag-sample measurement of various constituents in the exhaust gas of the gasoline engines installed in passenger cars and light-duty trucks. The report concentrates on the measurement of the following components in exhaust gas: hydrocarbons (HC), carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), and nitrogen oxides (NOx). NOx is the sum of nitric oxide (NO) and nitrogen dioxide (NO2). A complete procedure for testing vehicles may be found in SAE J1094.

Restricted Hardenability Bands for Selected Alloy Steels

1993-09-01
HISTORICAL
J1868_199309
Restricted hardenability steels have been in use for some time but the specific restrictions for a particular grade depend upon customer needs and vary from mill to mill. Such steels are desirable to provide more controlled heat treatment response and dimensional control for critical parts. Because of increasing interest in steels with restricted hardenability, the SAE Iron and Steel Technical Committee directed Division 8 to prepare a set of standard steels with restricted hardenability. In 1993, the American Society for Testing and Materials (ASTM) adopted the twelve SAE restricted hardenability steels and added ten more. SAE decided to include in SAE J1868 the additional 10 steels. In general, steels with restricted hardenability (RH Steels) will exhibit a hardness range not greater than 5 HRC at the initial position on the end-quench hardenability bar and not greater than 65% of the hardness range for standard H-band steels (SAE J1268) in the "inflection" region.
