Circuit Protection and Switch Device Committee
This information report gives typical requirements for an anechoic chamber in which the system susceptibility of an operating motor vehicle to electromagnetic fields can be determined in the frequency range of 20 MHz to 18 GHz. Because of the large cone sizes required for 20 MHz cut-off, several anechoic facilities have been designed with lower cut-off frequencies of 200 MHz or greater. Testing below cut-off is then accomplished using customized antennas at reduced accuracy. Users should carefully review their testing requirements before undertaking the construction of a test facility the magnitude of an anechoic chamber. Other test approaches include, but are not limited to, open field testing per SAE J1338 and mode stirred reverberation chambers.

This information report gives the procedures for use and operation of a large transverse electromagnetic (TEM) mode cell for the determination of electromagnetic (EM) radiated susceptibility of equipment, subsystems and systems (whose dimensions are less than 3 m × 6 m × 18 m) in the frequency range 10 kHz - 20 MHz. Several large TEM cells have been designed and constructed by various organizations for EMP and high power CW testing. Two cell designs and associated instrumentation are included for example purposes in this report. Other cell configurations have also been constructed. Users should consult the literature before undertaking a project of this magnitude for other cell and instrumentation designs.

Surface Enhancement Committee
The requirements for setting up and operating the machinery, the microphone array and the size of the hemispherical measurement surface are given in this standard. This standard shall be used in conjunction with ISO 4872-1978, which gives the basic criteria for the acoustic environment, instrumentation, microphone positions, procedures for the measurement of the A-weighted sound pressure levels and the calculation of the A-weighted sound power levels.
SLTC - Earth Moving Machinery Sound Level
This SAE Recommended Practice defines a procedure, which will aid in assessing the contaminant sensitivity of hydraulic valves. The approach taken defines a test procedure with flexibility for testing valves in a wide range of contamination levels. The user of this procedure must establish the contamination levels for testing. Three levels are suggested which should cover the range for most valve applications. This procedure does not establish the contaminant sensitivity requirements for any valve. The user of this procedure needs to be aware of the system contamination level that the valve will operate in and select test contamination levels significantly higher than the operating level to assess the suitability of the valve. The test procedure permits a valve to be tested without disassembly and therefore permits protection of proprietary design information.

The purpose of this test procedure is to provide a uniform method of testing commercial spherical rod end bearings to determine their performance characteristics under specific application situations. This procedure is an extension of the dimensional requirements for spherical rod end bearings as set forth in SAE J1120 and J1259. The loads, number of cycles, definition of failure, etc., are to be agreed to by the user and supplier. This procedure can also be used as the basis for testing ball joints covered by SAE J490.
Materials, Processes and Parts Council
The purpose of this SAE Recommended Practice is to provide standardized dimensions for mounting starting motors. (See Figures 1 through 4.) It is recommended that a full register diameter having a minimum depth of 2.54 mm (0.100 in) be provided in the flywheel housing to insure proper control of gear center distance and clearance between pitch diameters. The clearance between the starting motor pilot diameter and the register diameter in the flywheel housing should be 0.03 mm (0.001 in) minimum to 0.25 mm (0.010 in) maximum. Text noted with an asterisk in Figures 1, 2, and 3, should not exceed root radius of pinion in order to provide clearance for the flywheel. The face of the starting motor mounting flange should be relieved at its junction with the pilot diameter to avoid mounting interference with flywheel housing. For backlash allowance between the pinion and ring gear refer to SAE J543. Dimensional units—millimeter (inch)

MTC8, Tire and Rim
While this report does not include a discussion of all of the available data defining human response or address all body areas, for those areas addressed it does utilize references generally judged by those in the field to be practical and meaningful guidelines for the development of human surrogates. This report is intended to be a “living” document that will be updated periodically. A number of problems need to be addressed in defining human impact response characteristics. There is the problem of human response variability from subject to subject in volunteer tests. There is the problem of extrapolating such volunteer data which are obtained at low impact severities to higher impact severities using human cadaver response data obtained at injurious levels of impacts. Live animal experiments have been conducted over the years in an attempt to define human impact response and tolerance. The problem with using animal response data is the lack of geometric scaling techniques needed to
Human Biomechanics and Simulations Standards Committee
As a simulation of road driving, wind tunnel testing of full-size vehicles produces certain errors in the aerodynamic forces, aerodynamic moments, and surface pressures. The magnitude of these errors, in general, depends on the following: a Flow quality b Determination of the reference dynamic pressure c Wind tunnel floor boundary layer d Test section geometry and position of the car within that geometry e Shape of the vehicle f Blockage ratio: The ratio of the cross-sectional area of the vehicle to the cross-sectional area of the wind tunnel nozzle g Wheel rotation h Internal flow in the model The SAE Standards Committee, Open Throat Wind Tunnel Adjustments had as a goal to document the knowledge of the influence of model interference on wind tunnel test results for automotive open jet wind tunnels.

Engine Power Test Code Committee
This SAE Standard outlines the US standard for sending Advanced Traveler Information Services (ATIS) messages over various Bandwidth Reduced Media (BRM). It specifies the “over the air” format and method for such data messages at a bit level. The methodology allows a cooperative sharing of the media’s total bandwidth with other non-ATIS data services. It allows for further expansion to other ATIS messages such as transit schedules and weather use. It uses a common directory of messages to divide out those messages which are the subject of this specification from others. It is built upon the concept of “waveform neutrality” in that it can be hosted by a wide variety of media often found in the delivery of wireless data services (although it is also useful for wire line applications). This message set is incorporated into each medium (“host medium”) by a formatting process specific to each media. A graphical overview ofthis process is shown in Figure 1. The capacity and services
