This Aerospace Standard will define minimum light intensity in terms of "effective intensity" as defined in paragraph 3.5 of this standard and specified vertical and horizontal directions about the longitudinal and vertical axis of the airplane. It will also define flash rate and color for the anticollision light system.
This SAE Recommended Practice 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.
New methods are available to assist in evaluating the risk of impulse noise-induced hearing loss from inflatable devices, for example, airbags and seat belt pretensioners. This document presents some background on impulse noise measurement techniques and assessment criteria. Related information relative to test details, for example, preamplifier specifications and filtering methods and criteria, will be discussed in a future recommended practice.
This SAE Recommended Practice pertains to operator seats for the earthmoving category of off-road self-propelled work machines as defined in SAE J1116 JUN81. This recommended practice defines classes of earthmoving machines having similar characteristics which affect the vibration transmitted to the operator through the operator seat. This recommended practice establishes input data parameters for conducting operator seat vibration tests for the various classes. The purpose is to aid in the selection of an operator seat for a specific machine model and to reduce the amount of testing necessary to determine compliance with applicable standards and/or recommendations. Test procedures are specified in SAE J1384. Instrumentation and measurement procedures are specified in SAE J1013 JAN80.
The scope of this SAE Standard is the definition of the functional, environmental, and life cycle test requirements for electrically operated backup alarm devices primarily intended for use on off-road, self propelled work machines as defined by SAE J1116 (limited to categories of 1) construction, and 2) general purpose industrial). This purpose of this document is to define a set of performance requirements for backup alarms, independent of machine usage. The laboratory tests defined in this document are intended to provide a uniform and repeatable means of verifying whether or nor a test alarm meets the stated requirements. For on-machine requirements and test procedures, refer to SAE J 1446.
This SAE Recommended Practice establishes the procedure for measuring the sound level of recreational motorboats at a position on the shore 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. Purpose This document specifies guidelines for sound level measurements made from the shoreline of recreational boating areas and is intended for recreational motorboats only.
This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is in a stationary test condition. This SAE Standard is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. Specific requirements are provided in this special test code to enable the sound pressure level at the operator's position, with the machine in a stationary test condition, to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version shall be fitted since this is the configuration most likely to exist when the machine is in actual use. This document will enable compliance with noise limits to be determined.
This procedure is applicable to high frequency squeal type noise occurrences for passenger car and light truck type vehicles that are used under conventional operating conditions. The procedure does not encompass the consequences associate with changes in environment relate to temperature and humidity variations. Purpose This recommended test practice is intended to establish a common universally recognized method for performing a series of screening test sequences that identify the propensity of a brake assembly to generate squeal noise under a variety of test conditions.
This procedure is intended for evaluating alarms on off-road self-propelled work machines while in a stationary, parked position. This SAE Standard is similar to ISO/DIS 9533, Earthmoving machinery--Machine mounted morward and reverse warning alarm--Sound test method. Purpose This SAE Standard outlines the procedures and sets criteria necessary to qualify an audible alarm when mounted on off-road self-propelled work machines as defined by SAE J1116 JUN86 (limited to categories 1. Construction, and 2. General Purpose Industrial). The purpose of an alarm is to warn personnel of a potential hazard of a machine moving in reverse under its own power, without undue discomfort or irritation to the operator. Alarm performance on the machine is a function of alarm design, condition, voltage at the alarm, and placement on the machine with respect to machine components. This procedure verifies that the combination of factors produce an audible alarm.
This SAE Recommended Practice establishes the instrumentation, test site, and test procedure for determining the maximum exterior sound level for snowmobiles.
This SAE Standard is used to determine the exterior A-weighted equivalent sound power level of static and in-place dynamic machines (dozer, loader, excavator, and backhoe) similar to the sound power obtained in ISO 6393 static and ISO 6395 dynamic sound power test procedures. Additional machine types, specifically sweepers and scrubbers, covered by SAE J2130 have been added, and other work machine types covered by SAE J1116 may be added with appropriate cycle descriptions and machine preparation. The recommended test procedures include conventional integrating sound pressure level methods or the sound intensity method using paired microphones. The sound intensity methodology provides a practical indoor alternative and permits measurement in the factory environment. The procedures in this document assume that the dominant sources are not highly sensitive to load (i.e., cooling fan, engine, track system).
The purpose of this SAE Aerospace Recommended Practice (ARP) is to establish recommendations for the design, installation and testing of air vehicle vapor cycle refrigeration systems. These recommendations are representative of the refrigerant cycles.
The purpose of this report is to provide information on ozone, its effects, generally accepted ozone exposure limits (aviation and non-aviation), and methods of its control in high altitude aircraft. Sources of information are listed and referenced in the text.
This SAE Recommended Practice applies to construction, general purpose industrial, forestry, and specialized mining machinery as categorized in SAE J1116. It describes the machine components and systems that should be disconnected, secured, or otherwise rendered inoperative. Deterrent systems or devices covered by this recommended practice are to be used when the machine is shut down per the manufacturer's shut down instructions. It is not the intent of this recommended practice to protect the machine or the authorized machine operator, or to protect against abuse, destructive vandalism, or theft. Purpose This recommended practice is a guide for locking or otherwise rendering inoperative the starting, control, and parking release systems to deter unauthorized machine or working tool movement while the machine is shut down.
Because of the special circumstances under which these tests were conducted, it is necessary to carefully define the limitations on the validity of the results. The measurements and the comparisons reported here apply only to the specific locations of the noise sources and microphones and only for the specific weather and ground-surface conditions existing at the time of the tests. It cannot be assumed that these conditions are representative of most field measurements of aircraft exterior noise.
