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 standard covers jacketed multi-conductor copper data cables for aerospace use.
This standard requires the developers and customer/users working as a team to plan and implement a reliability program that provides systems/products that satisfy the user’s requirements and expectations. The user’s requirements and needs are expressed in the form of the following four reliability objectives: The developer shall solicit, investigate, analyze, understand and agree to the user’s requirements and product needs. The developer, working with the customer and user, shall include the activities necessary to ensure that the user’s requirements and product needs are fully understood and defined, so that a comprehensive design specification and Reliability Program Plan can be generated. The developer shall use well-defined reliability- and systems-engineering processes to develop, design, and verify that the system/product meets the user’s documented reliability requirements and needs. The developer shall implement a set of engineering activities (included in this standard as
This SAE Aerospace Recommended Practice (ARP) addresses the general procedure for the best practices for minimizing uncertainty when calibrating thermal conductivity and cold cathode vacuum gauges, which includes the vacuum sensor(s) and accompanying electronics necessary for a pressure measurement to be made. It also includes the best practices for an in-process verification where limitations make it impossible to follow the best practices for minimizing uncertainty. Verifying the accuracy and operation of vacuum gauges is critical to ensure the maintenance of processes while under vacuum.
The scope of this SAE Aerospace Recommended Practice (ARP) is to establish the procedure for creating titles of aerospace tubing and clamp installation documents generated by SAE Subcommittee G-3E.
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 standard defines the requirements for fully replacing undesirable surface finishes using robotic hot solder dip. Requirements for qualifying and testing the refinished piece parts are also included. This standard covers the replacement of pure tin and Pb-free tin alloy finishes with SnPb finishes with the intent of subsequent assembly with SnPb solder. This dipping is different from dipping to within some distance of the body for the purposes of solderability; solder dipping for purposes other than full replacement of pure tin and Pb-free tin alloy finishes are beyond the scope of this document. It covers process and testing requirements for robotic dipping process and does not cover semi-automatic or purely manual dipping processes. This standard does not apply to piece-part manufacturers who build piece parts with a hot solder dip finish. It applies to refinishing performed by a robotic hot solder dip service supplier or production facilities at the customer, whenever the intent
This standard specifies the areas to be used in calculating stress or load values to be used in externally and internally threaded fastener procurement specifications for bolts, screws, nuts, and studs and for the information of designers.
