This specification covers a low-alloy steel in the form of bars, forgings, mechanical tubing, and forging or tubing stock.
This supplement forms a part of SAE Aerospace Specification AS85421. It shall be used to identify fitting standards citing this procurement specification.
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of snowmobiles in the stationary test mode. This test method is intended to provide an accurate measurement of exhaust and other engine noise and may be used to evaluate new and in-use snowmobiles to determine compliance with noise control regulations. Sound level measurements obtained with this test method are not intended as an engineering determination of overall machine noise. For this purpose, the use of SAE J192 is recommended.

This document does not include the qualification requirements for AMS1424 Type I fluids (these are provided in ARP6207).
This document applies to safety observers or spotters involved with the use of outdoor laser systems. It may be used in conjunction with AS4970.
This standard specifies the characteristics of the MJ profile metric series of screw threads, altered from ISO 68 M Profile, to include a mandatory controlled radius of 0.18042P to 0.15011P at the root of the external thread and with the minor diameter of both external and internal threads increased to provide a basic thread height of 0.5625H in order to accommodate the external thread maximum root radius. The following detailed requirements are included: a MJ basic profile and design profiles b Standard series of diameter-pitch combinations for nominal thread diameters from 1.6 to 200 mm c Standard thread classes and form tolerances d Formulae for thread dimensions and tolerances e Method of designating MJ threads f Inspection requirement g Tables for selected diameter-pitch combinations for aerospace screws, bolts, nuts, shaft and bearing retaining screw threads, and fluid fittings thread sizes h Tables for MJ screw threads limiting dimensions and tolerances i Symbols for MJ thread
This SAE Aerospace Recommended Practice (ARP) identifies the minimum requirements for the testing of insulated electrical wiring for on-aircraft, aeronautical and aerospace applications. The testing requirements defined herein, ensure that a wire fault can be found safely when using a high potential voltage tester (hipot). This test is intended to aid in finding a breach in the wire insulation, and not for the identification of the resistance of the insulation. The test method defined herein is limited to equipment which ia able to control and limit the DC output to 1500 VDC maximum. This type of wire dielectric tester is typically designed to trip on current leakage and not necessarily on arc detection. This test method is solely designed to identify gross/large wire insulation damage or degradation. For additional related information on this topic and related test methods, refer to the documents cited in Section 2. They are intended to aid the reader in the direction of this ARP and
This test method outlines the recommended procedure for performing the no-load rotational starting torque test on airframe rolling bearings. Bearings covered by this test method shall be antifriction ball bearings and spherical roller bearings.
This test method outlines the recommended procedure for performing static axial limit and ultimate load tests on rolling element bearings used in airframe applications. Bearings covered by this document shall be antifriction ball bearings and spherical roller bearings in either annular or rod end configurations.
This Aerospace Standard (AS) 5659/4 Physical Layer Specification provides guidance for the physical layer of optical networks which use Wavelength Division Multiplexing (WDM), within the AS5659 WDM LAN specification document family. The physical layer consists of the optical interconnections between the functional components of the network. Performance requirements for general interconnections are described. For guidance, standards are identified, corresponding to each of several environments, which describe physical layer design, installation, maintenance, and training.
This specification covers insulated wire for use in external aircraft antennas.
This specification covers a compressed non-asbestos fiber and acrylonitrile butadiene (NBR) rubber in the form of sheet.
This SAE Aerospace Recommended Practice (ARP) defines the test set-up requirements, general analysis procedures, and test report documentation for impact tests where photometric analysis of the high speed film or digital video will be required to obtain target paths (typically the Anthropomorphic Test Dummy (ATD) head path and knee path). Such tests support the requirements of AS8049 - Performance Standard for Seats in Civil Rotorcraft, Transport Aircraft and General Aviation Aircraft. These setup and analysis procedures are applicable to conventional, geometry based, two-dimensional analysis. If a more sophisticated technique that allows cameras to be installed at oblique angles for two or three-dimensional analysis is used, then the specific procedures required by that technique supersede any conflicting procedures contained herein. Some of the requirements that could be superseded include camera placement, optical data channel evaluation, camera to subject measurements, and scaling
This specification covers a corrosion resistant steel in the form of wire type identified under the Unified Numbering System as UNS S30500.
This document describes a process that may be used to perform the ongoing safety assessment for (1) GAR aircraft and components (hereafter, “aircraft”), and (2) commercial operators of GAR aircraft. The process described herein is intended to support an overall safety management program. It is associated with showing compliance with regulations and also establishing and meeting internal company safety standards. The process described herein identifies a systematic means, but not the only means, to assess continuing airworthiness. Ongoing safety management is an activity dedicated to assuring that risk is identified and properly eliminated or controlled. The safety management process includes both safety assessment and economic decision-making. While economic decision-making (factors related to scheduling, parts, and cost) is an integral part of the safety management process, this document addresses only the ongoing safety assessment process. This ongoing safety assessment process
This SAE Aerospace Recommended Practice (ARP) is intended as a guide toward standard practice for selection of nominal hex widths for fittings.
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.
