This SAE Recommended Practice applies to floodlamp, headlamp, and general service lamp units intended for use on off-road self-propelled work machines classified as construction, general purpose industrial and forestry machines, as noted in SAE J1116. Construction and industrial machinery is normally operated off highways, therefore, this document is not intended to be used as a basis for regulations by those having authority over motor vehicles used on public highways. Other performance and dimensional information is contained in SAE J572 and J760.
This SAE Standard covers complete general and dimensional specifications for the various types of tube fittings intended for general application in the automotive, appliance, and allied fields. See SAE J1131 for the performance requirements of reusable (push to connect) fittings intended for use in automotive air brake systems.
This SAE Recommended Practice covers the use of preferred bolt and capscrew sizes, wherever applicable, on construction and industrial machinery to ease serviceability. Designers, in their efforts to determine the proper fastener for heavy equipment, sometimes overlook the practical aspects of serviceability. When a particular component requires frequent service, it is much faster and easier for the serviceman to work with common size, easily distinguished bolts and capscrews which require a minimum of tools. Section 4 lists eight diameters of recommended bolts and capscrews, some of which can be found in any hardware store, require only standard tools, are easy to distinguish, and at the same time cover proof loads from 1043 kg (2300 lb) on up at convenient intervals. While some applications may require other sizes and/or fine threaded fasteners for greater camping forces and/or area restrictions, the convenience of UNC threads in the sizes indicated is preferred wherever possible.
This SAE Recommended Practice presents minimum defrosting system performance requirements for trucks, buses, and multipurpose vehicles when tested according to SAE J381. It is the intent that this document will be reviewed and revised to reflect technological progress in vehicle defroster systems.
This SAE Recommended Practice provides minimum performance requirements and uniform procedures for fatigue testing of wheels intended for normal highway use and temporary use on passenger cars, light trucks, and multipurpose passenger vehicles. For heavy truck wheels and wheels used as duals, see SAE J267. For wheels used on trailers drawn by passenger cars, light trucks, or multipurpose vehicles, see SAE J1204. These minimum performance requirements apply only to wheels made of materials included in Tables 1 to 4.
This SAE Recommended Practice covers the mechanical, chemical, and dimensional requirements of oil-tempered carbon-steel spring wire used in the automotive and related industries. It is especially intended for the manufacture of mechanical springs and wire forms which are not subjected to a large number of high stress cycles. Class I wire is intended for moderate stress and Class II for higher stress level applications. This document also covers the processing requirements for springs fabricated from this wire.
This SAE Recommended Practice describes a test procedure for evaluating the abrasion resistance characteristics of webbing when used in hardware of seat belt assemblies such as those described in SAE J140.
This SAE Recommended Practice covers the physical and chemical requirements of oil- tempered carbon-steel valve spring quality wire used for the manufacture of engine valve springs and other springs requiring high-fatigue properties. This document also covers the processing requirements of springs fabricated from this wire.
This SAE Recommended Practice covers a high quality, hard-drawn, steel spring wire, uniform in mechanical properties, intended for the manufacturer of spring and wire forms subjected to high stresses or requiring good fatigue properties. It covers processing requirements of springs fabricated from this wire.
This SAE Recommended Practice specifies the general characteristics and test procedure to define the minimum characteristics, performance, and durability requirements. It is applicable to remanufactured assemblies (factory rebuild) only. This document applies to master cylinder assemblies and components of current established designs but does not cover fluid level sensors, integral proportioning valves or those master cylinders used in anti-lock brake or traction control systems. These will be covered by other standards. The minimum characteristics, performance, and durability requirements are specified in SAE J1694.
The test is designed to evaluate the frontal impact resistance of wheel and tire assemblies used with passenger cars, light trucks and multi-purpose vehicles. The test is specifically related to vehicle pothole tests that are undertaken by most vehicle manufacturers. The scope has been expanded to allow the use of a striker that can be angled to preferentially impact the inboard and outboard wheel flange. For side impact of the outboard rim flange only, please refer to SAE J 175. This SAE Recommended Practice does not provide standards of performance.
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.
This classification system tabulates the properties of vulcanized rubber materials (natural rubber, reclaimed rubber, synthetic rubbers, alone or in combination) that are intended for, but not limited to, use in rubber products for automotive applications. NOTE 1: The SAE Committee on Automotive Rubber Specifications (CARS) has the sole responsibility for SAE J200. CARS Works closely with and receives input from ASTM Subcommittee D11.30 on Classification of Rubber Compounds with the goal to keep SAE J200 and ASTM D 2000 technically equivalent. Candidate materials presented for development of new tables or for inclusion in Tables A1 or A2 of SAE J200 or Table X1.1 of ASTM D 2000 shall be initiated with the SAE CARS Committee. The procedure to be followed is detailed in Appendix C of SAE J200. NOTE 2: This document may serve many of the needs of other industries in much the same manner as SAE numbered steels.
This SAE Standard covers the performance requirements for protective covers for gasoline fuel tubing. The ultimate performance of the protective cover can be highly dependant on the interaction of the fuel line tubing and protective cover. Therefore, it is recommended that specific tubing and cover combinations be tested as an assembly to qualify to this document. This document is intended to provide guidance to the engineer on the key performance parameters for protective covers for gasoline fuel tubing. This document is designed to allow selection of predetermined performance levels for these key performance parameters. The engineer may select a specification by the use of a line call-out designation, which will denote the pertinent characteristics of the cover material and/or the tube/cover assembly and their corresponding performance criteria. The engineer is not required to select every characteristic, but only those deemed important to the application.
