This SAE Aerospace Recommended Practice (ARP) recommends a methodology to be used for the design, analysis and test evaluation of modern helicopter gas turbine propulsion system stability and transient response characteristics. This methodology utilizes the computational power of modern digital computers to more thoroughly analyze, simulate and bench-test the helicopter engine/rotor system speed control loop over the flight envelope. This up-front work results in significantly less effort expended during flight test and delivers a more effective system into service. The methodology presented herein is recommended for modern digital electronic propulsion control systems and also for traditional analog and hydromechanical systems.
This SAE Standard establishes a test method and a definition for disclosing the performance of suction/blower fans when applied to self-propelled sweepers that solely use a pneumatic conveyance means for the collection and transfer of “sweepings” into a collection hopper.
This SAE Recommended Practice establishes minimum requirements for electric hourmeters for general vehicular applications.
This SAE Recommended Practice provides laboratory test procedures for testing headlamp aim test machines to verify their ability to aim or to inspect the aim of headlamps, fog lamps, and auxiliary high beam lamps. This specification does not apply to aiming devices of the kind covered by SAE J602. This specification does not apply to motorcycle headlamps.
The primary purpose of vehicle forward lighting is not to see the world but to see the road! In their simplest form, headlights help drivers negotiate a safe path on the road. They do this by lighting the roadway according to (a multitude of) specific standards. For decades, discussions concerning the niceties of illuminating potential obstacles in the roadway were little more than an academic pursuit as there simply were not sufficient lumens available from filament light sources to achieve all of the desired tasks no matter how worthy they might be. Not unexpectedly, the technology has evolved with the introduction of high output metal-halide sources, multi-task standards combined with multilevel lighting devices and discrete LED sources offering high luminous efficiencies and the means to deliver the light where it can be most useful. The question now becomes one of determining where the available light should be directed. Every standard advisory group, industry, manufacturer and
The Mounting Height Task Force was tasked to determine the extent of the problem(s) associated with vehicle headlamps mounted at or above the level of the mirror(s) in passenger vehicles; the level of glare exposure caused by high-mounted headlamps; the appropriate height differential needed to maintain a glare level consistent with past and/or current passenger vehicle headlamp mounting; and the necessary headlamp mounting height necessary to control mirror glare at an accepted/acceptable level. The report herein addresses these passenger vehicle mounting height issues.
This SAE Recommended Practice describes the test procedure for conducting a rollover test using a dolly fixture designed to laterally trip a vehicle into a roll. Its purpose is to establish a recommended test procedure which will standardize the procedure between different test facilities. A description of the test procedure, test instrumentation, photographic/video coverage, and the rollover fixture is included.
This SAE Standard measures the percent thermal efficiency of materials in sleeve form used to contain heat or insulate around a hot component. The percent thermal efficiency (%TE) is determined by measuring the power difference expended by the heat source (cartridge heater) with and without the test sleeve at the specified temperature. See SAE J2302 to measure radiant heat flow of sleeves.
The following is a list of the most common terminology used in describing automatic transmission functions.
SAE J1717 is an advisory document suggesting minimum recommended testing, appearance evaluation, and protocol for specifying the recommendations with regard to Singular Unassembled Automotive Interior Trim Parts.
This SAE Standard is intended to serve as a guide for the collection of physical, mechanical, and thermal properties of fiber-reinforced polymer composite materials for automotive structural applications. This document attempts to utilize test methods applicable to the widest range of structural materials and processes without compromising the integrity of the data being sought. A summary of the material characterization is shown in Section 15.

This SAE Aerospace Standard (AS) aims at identifying the design criteria and testing methods adequate to guarantee the ultimate load and operational dependability of cargo restraint strap assemblies with a typical 22250 N (5000 lbf) rated ultimate tension load capability, as used by the airline industry in order to restrain cargo on board civil transport aircraft during flight: a cargo loaded and tied down onto airworthiness certified air cargo pallets, themselves restrained into aircraft lower deck or main/upper deck cargo systems and meeting the requirements of NAS 3610 or AS36100, or b non-unitized individual pieces of cargo, or pieces of, cargo placed onto an unrestrained (“floating”) pallet into either lower deck or main deck containerized cargo compartments of an aircraft.
These specifications cover molded cups 51 mm (2 in) in diameter and under, compounded from high temperature resistant rubber for use in hydraulic actuating cylinders employing motor vehicle brake fluid conforming to the requirements specified in SAE J1703 and SAE J1705. These specifications cover the performance tests of hydraulic brake cups under specified conditions and do not include requirements relating to chemical composition, tensile strength, and elongation of the rubber compound. Disc brake seals are not covered by this document.
This specification applies to a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. This specification describes services for all seven protocol layers. In the layer 7 specification, it includes a description of the types of messages used by applications to exchange application and network management data.
This specification covers a corrosion- and heat-resistant iron-nickel-chromium alloy in the form of bars and forgings 4.0 inches (102 mm) and under and forging stock of any size.
This SAE Recommended Practice identifies and defines the specifications most commonly used to describe high-speed steel track and articulated rubber-tired clam bunk skidders. The illustrations used are not intended to be descriptive of any existing machine or dictate a combination needed for a particular logging situation. The dimensions indicated are basic and may be supplemented by the individual machine manufacturer.
This SAE Aerospace Recommended Practice (ARP) is intended to be used for laser systems mounted on aircraft and propagated into navigable airspace. This does not include lasers onboard aircraft where the beam is contained within an enclosure so that the beam cannot enter into airspace, nor does it include lasers from satellites and spacecraft in outer space. It may be used in conjunction with AS4970, ARP5535, ARP5572, ARP5293, and the ANSI Z136 laser safety standards.
This SAE Aerospace Standard covers high strength commercial sockets and universal sockets which possess the strength, clearances, and internal wrenching design so configured that, when mated with hexagon (6 point) fasteners, they shall transmit torque to the fastener without bearing on the outer 5% of the fastener’s wrenching points. This document provides additional requirements beyond ANSI B107.5 appropriate for aerospace use. Inclusion of dimensional data in this document is not intended to imply all of the products described therein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.

In order to compare test results obtained from different crash test facilities, standardized coordinate systems need to be defined for crash test dummies, vehicle structures, and laboratory fixtures. In addition, recorded polarities for various transducer outputs need to be defined relative to positive directions of the appropriate coordinate systems. This SAE Information Report describes the standardized sign convention and recorded output polarities for various transducers used in crash testing.
