Test Method for Determining Power Consumption of Engine Cooling Fan Drive Systems

1994-09-01
HISTORICAL
J1342_199409
The technique outlined in this SAE Recommended Practice was developed as part of an overall program for determining and evaluating fuel consumption of heavy-duty trucks and buses, but it is applicable to off highway vehicles as well. It is recommended that the specific operating conditions be carefully reviewed on the basis of actual installation data. Cooling requirements are affected by all heat exchangers that are cooled by the fan drive system. These may include radiators, condensers, charge air coolers, oil coolers, and others. Because of the variation in size, shape, configuration, and mountings available in cooling fans and fan drive systems, specific test devices have not been included. Using known power/speed relationships for a given fan, this procedure can be used to calculate the fan drive system’s power consumption for engine cooling systems using fixed ratio, viscous or speed modulating, and mechanical on/off fan drives including electronically activated fan drives.

Felling Head Terminology and Nomenclature

1994-09-01
HISTORICAL
J1272_199409
This SAE Standard is intended to describe the basic types of felling heads, including those with bunching capabilities, that are attachments to a self-propelled machine. Only the major components that are necessary to describe the functions to the felling head, and to apply the principles of the recommended practice are included. Illustrations used are not intended to include all existing felling heads or to describe any particular manufacturer's variation. The purpose of this document is to set forth accepted definitions for functions of tree felling heads and to classify and establish nomenclature for major components and parts peculiar to these machines.

Disc Wheel Hub/Spoke Wheel and Axle Interface Dimensions-Commercial Vehicles

1994-09-01
HISTORICAL
J1842_199409
This SAE Recommended Practice is intended for hubs and spoke wheels used on Class 7 and 8 truck/truck-tractor nonpowered front axles, powered and nonpowered rear axles, and trailer axles. The purpose of this document is to establish dimensional guidelines to promote a functional standardization of wheel hubs and spoke wheels in the areas of fasteners, bearing cups, seal bore, and axle drive shaft or hub cap attachment. This document is not intended to exclude the use of wheel hub designs which do not meet the dimensional guidelines for use on defined axle configurations.

Describing and Measuring the DriverS Field of View

1994-08-01
HISTORICAL
J1050_199408
This SAE Recommended Practice establishes a uniform method for describing and measuring the driver's field of view. The document describes three methods for measuring the direct and indirect fields of view and the extent of obstructions within those fields. The first method uses any single pair of eye points to determine the fields or obstructions that would be seen by an individual driver. The second method uses the SAE Eyellipses defined in SAE J941 to determine the largest fields or obstructions that would be seen for a given percentage of the driving populations. The third method uses specific eye points defined in SAE J941 to measure the extent of a specific field of view or obstruction for which those points were developed.

RESIDUAL ALIGNING MOMENT TEST

1994-08-01
CURRENT
J1988_199408
This SAE Recommended Practice describes the determination of tire pull force properties for an uninclined tire (SAE J670e) on a laboratory flat surface tire force and moment machine. It is suitable for accurately determining pull forces and residual aligning moments for passenger and light-truck tires. These properties are important determinants of vehicle trim (See section 2.1.2). They describe steady-state, free-rolling pull effects ascribable to tires. The test method described in this document is suitable for comparative evaluation of tires for research and development purposes. The method is also suitable for modeling when followed carefully.

Test Method for Determining Blocking Resistance and Associated Characteristics of Automotive Trim Materials

1994-08-01
HISTORICAL
J912_199408
This test method is designed to indicate the degree of surface tackiness, color transfer, loss of embossment, and surface marring when two trim materials are placed face to face under specific conditions of time, temperature, and pressure. These specific conditions are not dictated in this test procedure but will be found in the material standards which govern each type of trim material to be tested.

Truck Deformation Classification

1994-08-01
HISTORICAL
J1301_199408
The scope and purpose of this SAE Recommended Practice is to provide a classification system for deformation sustained by trucks involved in collisions on the highway. Application of the document is limited to medium trucks, heavy trucks, and articulated combinations. The TDC classifies collision contact deformation, as opposed to induced deformation, so that the deformation is segregated into rather narrow limits or categories. Studies of collision deformation can then be performed on one or many data banks with assurance that data under study are of essentially the same type. Many of the features of the SAE J224 MAR80 have been retained in this document, although the characters within specific columns vary. Each document must therefore be applied to the appropriate vehicle type. It is also important to note that the Truck Deformation Classification (TDC) does not identify specific vehicle configurations and body types.

Identification Terminology of Mobile Forestry Machines

1994-08-01
HISTORICAL
J1209_199408
This SAE standard describes a procedure and the terminology for identifying and classifying mobile forestry machines which may be portable or self-propelled. Identification is determined by endpoint usage as intended by the manufacturer's design objectives. This document applies to machines that are designed for use in site preparation, planting, transporting, and processing wood and wood fiber. Specifically excluded are machines used exclusively in sawmills or wood yards, on-highway transport vehicles, and aerial vehicles.

HISTORICAL
J1361_199408
This test method is applicable for rating various materials, such as automotive trim materials and insulation composites, for their ability to resist heat transfer, heat degradation, odor, smoking, and exothermic reaction. The purpose of this testing method is to obtain comparative data which can be used to evaluate heat resistance and thermal insulation properties of various materials or composites when subjected to time and temperature conditions which reflect "in-car" situations.

HISTORICAL
J986_199408
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the exterior sound level for passenger cars, multipurpose vehicles, and light trucks having a gross vehicle mass rating of 4540 kg or less. The test procedure is characterized by having fixed initial conditions, i.e., an as-specified initial vehicle speed and gear selection at a fixed start point on the test site. Full-throttle acceleration and closed-throttle deceleration of the vehicle are included in this procedure. Sound levels determined in accordance with this document are dependent on the performance capability of the test vehicle, as influenced by power-to-mass ratio and overall powertrain gear ratio.
