This SAE Standard establishes the test procedure, environment, and instrumentation for determining the exhaust sound pressure levels of motorcycles under stationary conditions. Since initial publication, it has been successfully applied to regulation and monitoring of sound pressure levels of off-highway vehicles, and that remains its recommended application. Users of SAE J1287 for the purpose of roadside enforcement of sound pressure levels for on-highway motorcycles have reported difficulties with its implementation in that application. In response, SAE J2825 was developed, and is recommended for measurement of exhaust sound pressure levels of stationary on-highway motorcycles. Care must be taken not to confuse stationary sound pressure levels with total motorcycle sound pressure levels. This test does not evaluate total motorcycle sound during operation. For this purpose, SAE J331 or SAE J47 is recommended. Any allowable sound limits (dBA) set in relation to SAE J1287 for exhaust

This SAE Recommended Practice describes methods for determining total and specular reflectance for mirrors with flat and curved surfaces and a method for determining diffuse reflectance and haze for mirrors with flat surfaces.

The air cranking system components, which include the tank, valve, hose, and starter, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold temperatures, therefore, the initial selection of these components, needs to consider low-temperature engine torque requirements. To insure an adequate air cranking system is obtained, it is important that proper test procedures are used for obtaining the cranking load requirements of the engine.
Vehicle EE System Diagnostics Steering Committee
This document describes analytical methods for calculating the attenuation of the level of the sound propagating from an airplane to locations on the ground and to the side of the flight path of an airplane during ground roll, climbout after liftoff, and landing operations. Both level and non-level ground scenarios may be modeled using these methods, however application is only directly applicable to terrain without significant undulations, which may cause multiple reflections and/or multiple shielding effects. This attenuation is termed lateral attenuation and is in excess of the attenuation from wave divergence and atmospheric absorption. The methods for calculating the lateral attenuation of the sound apply to: turbofan-powered transport-category airplanes with engines mounted at the rear of the fuselage (on the sides of the fuselage or in the center of the fuselage as well as on the sides) or under the wings propeller-driven transport-category or general-aviation airplanes

This document describes the requirements of the following test methods for counterfeit detection of electronic components: a Method A: General EVI, Sample Selection, and Handling b Method B: Detailed EVI, including Part Weight measurement c Method C: Testing for Remarking d Method D: Testing for Resurfacing e Method E: Part Dimensions measurement f Method F: Surface Texture Analysis using SEM The scope of this document is focused on leaded electronic components, microcircuits, multi-chip modules (MCMs), and hybrids. Other EEE components may require evaluations not specified in this procedure. Where applicable this document can be used as a guide. Additional inspections or criteria would need to be developed and documented to thoroughly evaluate these additional part types. If AS6171/2 is invoked in the contract, the base document, AS6171 General Requirements shall also apply.

This SAE Recommended Practice specifies a method to reduce and stabilize the moisture of products containing brake friction material (disc brake pads, drum brake shoes, friction blocks) so the parts are conditioned and maintained in a stable low moisture state.

“An Assessment of Planar Waves” provides background on some of the history of planar waves, which are time-dependent variations of inlet recovery, as well as establishing a hierarchy for categorizing various types of planar waves. It further identifies approaches for establishing compression-component and engine sensitivities to planar waves, and methods for accounting for the destabilizing effects of planar waves. This document contains an extensive list and categorization (see Appendix A) of references to aid both the newcomer and the practitioner on this subject. The committee acknowledges that this document addresses only the impact of planar waves on compression-component stability and does not address the impact of planar waves on augmenter rumble, engine structural issues, and/or pilot discomfort.
