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 SAE Aerospace Recommended Practice (ARP) establishes methods for testing airframe rolling element bearings. The purpose of ARP5483 and its associated slash sheets is to document test methods commonly used to evaluate airframe bearings. These test methods may be referenced in standards, purchase orders, etc. when the test is deemed appropriate to the intended use of the bearing by the end user of the bearing. These test methods are not intended to encompass every conceivable requirement for an airframe bearing. The end user of the bearing must exercise engineering judgment to determine the most appropriate standard and/or nonstandard tests for the application.
The purpose of this Standard is to provide an integrated set of fundamental processes to aid a developer in the engineering or reengineering of a system. Use of this Standard is intended to help developers a) establish and evolve a complete and consistent set of requirements that will enable delivery of feasible and cost-effective system solutions; b) satisfy requirements within cost, schedule, and risk constraints; c) provide a system, or any portion of a system, that satisfies stakeholders over the life of the products that make up the system. NOTE—The term product is used in this standard to mean: a physical item, such as a satellite (end product), or any of its component parts (end products); a software item such as a stand-alone application to run within an existing system (end product); or a document such as a plan, or a service such as test, training, or maintenance support, or equipment such as a simulator (enabling products). d) provide for the safe and/or cost-effective
This SAE Aerospace Standard (AS) documents and establishes common industry practices, and screening and qualification testing, of Plastic Encapsulated Microcircuits (PEMs) for use in military and avionics application environments.
This SAE Aerospace Recommended Practice (ARP) provides guidelines for abuse load testing of a deployable Individual Video System (IVS). The abuse load testing defined in this ARP is intended to only address the evaluation of the deployable IVS regarding stowage of the system and injurious projections/protrusions as a result of passenger interaction with the video system. Other aspects of the video system design or qualification may require additional testing or analysis and are outside the scope of this ARP. This ARP is not intended to address customer satisfaction or reliability aspects of individual designs.
This document provides guidance for in-flight rest facilities provided for use by cabin crew on commercial transport airplane. This document is applicable to dedicated cabin crew rest facilities with rigid walls. The facility includes a bunk or other surface that allows for a flat sleeping position, is located in an area that is temperature-controlled, allows the crew member to control light, and provides isolation from noise and disturbance.
This Aerospace Standard establishes the preferred diameter-pitch combinations of ISO metric 60° screw threads recommended for use in the aerospace industry for metric module bolts and nuts.
This slash sheet specifies the operational parameters and characteristics of a particular implementation of the SAE Linear, Token Passing Bus (LTPB) Interface Unit. This slash sheet defines the following: a The physical media interface: This slash sheet specifies the characteristics of the optical interface to the physical bus media. b The minimum and maximum timing requirements for operation of this implementation of the LTPB. c The data coding used to encode and decode the data for transmission. d The default values to be loaded into the timers of the LTPB interface at power-up prior to intervention by the host processor.
This specification establishes the procedure for installing hardened key types studs and inserts, eliminating the need for broaching key slots. It also defines the hole preparation necessary to install the studs and inserts.
This SAE Aerospace Recommended Practice (ARP) establishes a method for evaluating the particulate matter extracted from the working fluid of a hydraulic system or component using a membrane. The amount of particulate matter deposited on the membrane due to filtering a given quantity of fluid is visually compared against a standard membrane in order to provide an indication of the cleanliness level of the fluid.
This specification defines the requirements for a threaded rigid coupling assembly, which utilizes ferrule type machined tube end fittings, to join tubing and components in aircraft fuel, vent, and other systems. This coupling assembly is designed for use from −65 to 200 °F and at 125 psig operating pressure.
