This SAE Aerospace Recommended Practice (ARP) outlines recommended ramp pavement marking standards for proper guidance and positioning of GSE on commercial transport aircraft parking and handling stands (gates), in line with International Civil Aviation (ICAO) recommendations applicable to airport aprons. Throughout this document, the minimum essential criteria are identified by use of the key word “shall”. Recommended criteria are identified by use of the key word “should” and, while not mandatory, are considered to be of primary importance in providing safety effective ramp markings. Deviation from recommended criteria should only occur after careful consideration and thorough service evaluation have shown alternate methods to provide an equivalent level of safety.

This procurement specification covers rivets fabricated from an aluminum alloy designated as 1100-H14, strain hardened.
This SAE Recommended Practice has been established to provide direction for the design and installation of an identification number (IN) as assigned to vehicle engines, transmissions, and transaxles. The IN is used for tracking or traceability of these components. In adhering to these recommended practices, facility of application in factory production and appearance quality are matters for manufacturer control. Reference SAE J853.
This SAE Recommended Practice establishes a standard method to perform screening test sequences that identify a brake friction material’s effectiveness under various test conditions. The result is an evaluation of brake friction material effectiveness under a set of defined braking conditions considered most relevant to automobile braking system development.
This SAE Recommended Practice establishes the test procedure, environment, and instrumentation for determining the maximum sound level potential for motorcycles under wide open throttle acceleration and closed throttle deceleration.
This specification covers one type of epoxy-resin-impregnated carbon fibers in the form of eight harness satin fabric woven from continuous fiber tow.
This SAE Aerospace Recommended Practice (ARP) is intended to be a guide for defining automatic test equipment (ATE) methods to be used in performing electrical acceptance tests to ensure repeatability and compatibility of results between manufacturers and between manufacturer and user.
AS5653 may be applied to Air Vehicles and Stores implementing MIL-STD-1760 Interface Standard for Aircraft/Store Electrical Interconnection System.
The testing techniques outlined in this SAE Recommended Practice were developed as part of an overall program tor testing and evaluating fuel consumption of heavy duty trucks and buses. The technique outlined in this document provides a general description of the type of equipment and facility which is necessary to determine the power consumption of these engine-driven components. It is recommended that the specific operating conditions suggested throughout the test be carefully reviewed on the basis of actual data obtained on the specific vehicle operation. If specific vehicle application is not known, see SAE J1343.
The recommended practice describes a design standard that defines the maximum recommended voltage drop of the starting motor main circuits, as well as control system circuits, for 12/24-V starter systems. The battery technologies used in developing this document include the flooded lead acid, gel cell, and AGM. Starting systems supported by NiCd, Lithium Ion, NiZn, etc., or Ultracaps are not included in this document. This document is not intended to be updated or modified to include starter motors rated at voltages above the nominal 24-V electrical system. The starter is basically an electrical-to-mechanical power converter. If you double the available battery power in, you double the peak mechanical power out and double the heat losses. This means that we have to pay special attention to how battery power changes when we change the battery voltage and the effects it may have in overpowering the cranking system. A new stand-alone document would need to be developed to address
This specification covers an ethylene propylene (EPDM) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.
This specification covers aluminum alloy die castings.
This SAE Recommended Practice is intended for use in testing and evaluating the approximate performance of engine-driven cooling fans. This performance would include flow, pressure, and power. This flow and pressure information is used to estimate the engine cooling performance. This power consumption is used to estimate net engine power per SAE J1349. The procedure also provides a general description of equipment necessary to measure the approximate fan performance. The test conditions in the procedure generally will not match those of the installation for which cooling and fuel consumption information is desired. The performance of a given fan depends on the geometric details of the installation, including the shroud and its clearance. These details should be duplicated in the test setup if accurate performance measurement is expected. The performance at a given air density and speed also depends on the volumetric flow rate, or the pressure rise across the fan, since these two
The techniques outlined in this SAE Recommended Practice were 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 cooling systems using the types of drives listed below. This power consumption may then be used in determining engine net power per SAE J1349. For more
This specification covers a style 7781 glass cloth impregnated with a heat-curable polyester resin system, the resin being processed to a “B” stage condition, and furnished in the form of continuous rolls.
This standard provides a test method for determining the torque-tension relationship of both external and internal metric threaded fasteners for the purpose of measuring the frictional characteristics of the threaded fasteners. The results obtained by this test are relevant to the test conditions only and should not be utilized for specific applications.
This SAE Standard was developed to provide a method for indicating the direction of engine rotation and numbering of engine cylinders. The document is intended for use in designing new engines to eliminate the differences which presently exist in industry.
This SAE Standard provides a system for specifying significant material properties of thermoplastic elastomers (TPEs) that are intended for, but not limited to, use in automotive applications. In all cases where provisions of this classification system would conflict with those of the detailed specifications for a particular product, the latter shall take precedence. This classification is based on SI units.
