This SAE Recommended Practice establishes the procedure for measuring the sound level of recreational motorboats in the vicinity of a shore bordering any recreational boating area during which time a boat is operating under conditions other than stationary mode operation. It is intended as a guide toward standard practice and is subject to change to keep pace with experience and technical advances.
To provide standard terminology and definitions with regard to ignition systems for spark-ignited internal combustion engines.
This SAE Standard covers the minimum requirements for design, construction, and testing of devices to prevent the propagation of backfire flame from within the gasoline engine to the surrounding atmosphere.
Counterfeiting of refrigerants has seen a dramatic rise over the past decades. This rise can be partially attributed to global restrictions placed on production and use of refrigerants by the 1987 Montreal Protocol, the 1997 Kyoto Protocol, and the 2016 Kigali Amendment to the Montreal Protocol [1, 2]. These protocols and the amendment regulate the gradual phase-out and strict regulations on the use of refrigerants with high Ozone Depletion Potential (ODP) and high Global Warming Potential (GWP). These protocols require that older refrigerants be replaced with more environmentally friendly products and necessitate redesigned, updated, or replaced equipment to operate efficiently with these new refrigerants.
This SAE Aerospace Recommended Practice (ARP) provides criteria for design and location of power supplies, controls, light fixtures, and associated equipment which are used to provide emergency illumination in transport aircraft, designed to comply with 14 CFR Part 25 (see Reference 1) for operation under 14 CFR Part 91 (see Reference 11) and 14 CFR Part 121 (see Reference 2), and also in compliance with FAA Advisory Circulars AC 25.812-1A (see Reference 3) and AC 25.812-2 (see Reference 10). It is not the purpose of an ARP to specify design methods to be followed in the accomplishment of the stated objectives.
This Aerospace Standard covers components of rotary flap assemblies to be used with portable equipment for peening of metal parts. The flap assemblies consist of a flap attached to a mandrel and shall be of the following sizes.
This SAE Recommended Practice specifies an intrusion resistance test method for glazing systems installed in motor vehicles. Intrusion resistance performance is determined not solely by the glazing but also by the glazing attachment to the vehicle and by the vehicle structure. Therefore, the glazing/attachment/vehicle structure must be tested as a single unit. This test determines intrusion resistance only. The test applies to those materials that meet the requirements for use as safety glazing materials as specified in ANSI/SAE Z26.1 or other applicable standards. The test applies to all installation locations.
The purpose of this SAE Recommended Practice is to provide guides toward standard conditions for operating marine hydraulic transmissions where push-pull cable control is applicable. For control cable information see SAE J917.
Since it is impossible to be all inclusive and cover every aspect of the design/validation process, this document can be used as a basis for preparation of a more comprehensive and detailed plan that reflects the accumulated “lessons learned” at a particular company. The following areas are addressed in this document: 1 Contemporary perspective including common validation issues and flaws. 2 A Robustness validation (RV) process based on SAE J1211 handbook and SAE J2628. 3 Design checklists to aid in such a RV process.
This SAE Standard establishes the requirements for a Class B Data Communication Network Interface applicable to all On-and OffRoad Land-Based Vehicles. It defines a minimum set of data communication requirements such that the resulting network is cost effective for simple applications and flexible enough to use in complex applications. Taken in total, the requirements contained in this document specify a data communications network that satisfies the needs of automotive manufacturers. This specification describes two specific implementations of the network, based on media/Physical Layer differences. One Physical Layer is optimized for a data rate of 10.4 Kbps while the other Physical Layer is optimized for a data rate of 41.6 Kbps (see Appendix A for a checklist of application-specific features). The Physical Layer parameters are specified as they would be detected on the network media, not within any particular module or integrated circuit implementation. Although devices may be
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.
This SAE Recommended Practice establishes the test procedure, environment, and instrumentation for determining the maximum exterior sound level of highway motor trucks and truck tractors over 4540 kg gross vehicle weight rating (GVWR) with governed engines under stationary vehicle conditions. The basic procedure involves a full throttle engine acceleration and a closed throttle deceleration with the engine inertia as the load.
This SAE Recommended Practice establishes a rating scale for subjective evaluations of noise and discomfort in motor vehicles. Through test procedures utilizing specific vehicles on specific roads, the scale may be utilized to assess the relative contributions of tires to noise and discomfort. The noise and ride comfort characteristics attributed to automotive tires have traditionally been estimated by subjectively assigning number designations (commonly on a 1 to 10 scale) to the audible and tactile sensations observed while traversing a given road course in a vehicle equipped with the tires under evaluation. Regardless of advances in objective measurements of tire properties related to noise and discomfort, subjective evaluation will continue to be necessary for the purpose of establishing the significance of such measurements. The rating scale of this recommendation is applicable to assessment of each of the wide variety of audible and tactile disturbances referred to by such terms
This SAE Information Report provides a compendium of terms, definitions, abbreviations, and acronyms to enable common terminology for use in engineering reports, diagnostic tools, and publications related to active safety systems. This information report is a survey of active safety systems and related terms. The definitions offered are descriptions of functionality rather than technical specifications. Included are warning and momentary intervention systems, which do not automate any part of the dynamic driving task (DDT) on a sustained basis (SAE Level 0 as defined in SAE J3016), as well as definitions of select features that perform part of the DDT on a sustained basis (SAE Level 1 and 2).

This SAE Aerospace Recommended Practice (ARP) sets forth design and operational recommendations concerning the human factors/crew interface considerations and criteria for vertical situation awareness displays. This is the first of two recommended practice documents that will address vertical situation awareness displays (VSAD). This document will focus on the performance/planning types of display (e.g., the map display) and will be limited to providing recommendations concerning human factored crew interfaces and will not address architecture issues. This document focuses on two types of VSAD displays: a coplanar implementation of a profile display (side projection) and a conventional horizontal map display; and a 3D map display (geometric projection). It is intended for head down display applications. However, other formats or presentation methods, such as HUDs, HMDs and 3D audio presentations may become more feasible in the future. Even though the relationship of the vertical
