This SAE Standard sets forth the procedures to be used in measuring sound levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116: • Crawler Loader• Grader• Log Skidder• Wheel Loader• Crawler Tractor with Dozer• Pipelayer• Dumper• Wheel Tractor with Dozer• Trencher• Tractor Scraper• Backhoe• Sweeper• Roller/Compactor• Hydraulic Excavator• Pad Foot Wheel Compactor with Dozer• Excavator and Wheel Feller-Buncher The instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle representing continuous medium to heavy work. The work cycles provide a repeatable reproduceable means to uniformly measure working machines against a “yard stick. A method to relate the time weighted average sound level at the operator station(s) to estimate operator sound exposure with part load work, supervision, and rest…

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 SAE Standard sets forth the instrumentation and procedure to be used in measuring sound pressure levels at the operator position for self-propelled off-road work machines as defined in SAE J1116. This document does not address the operation of safety devices such as backup alarms, horns, or accessories. This SAE document is applicable to machines that have operator stations where the operator can either stand or sit and will be either transported by, or walk with the machine during its operation. The sound levels obtained using this procedure are repeatable and representative of the higher range of sound levels generated by machines under actual field operating conditions. Due to variability of field operating conditions, this data is not intended to be used for operator noise exposure evaluations.

This SAE Standard sets forth the instrumentation and procedure to be used in measuring the exterior sound pressure levels for self-propelled off-road work machines as defined in sections 1, 3, 5 and 6 of SAE J1116. This document does not address the operation of safety devices such as backup alarms, horns, or accessories. The sound levels obtained by using the test procedures set forth in this document are repeatable and are representative of the higher range of sound levels generated by machines under actual field operating conditions. Due to the variability of field operating conditions, this data is not intended to be used for construction site boundary noise evaluations.

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). This test can be used as a substitute for the ISO 6393 static and ISO 6395 dynamic sound power tests for many machine types. The requirements for the machine setup and operation, and the microphone array and hemispherical measurement surface are given…

This SAE Standard sets forth measurement procedures and instrumentation to be used for determining a “representative” sound level during a representative time period at selected measurement locations on a construction site boundary. The document is not intended for use in determining occupational hearing damage risk. Determination of a representative time period is left to the judgment of the user.

This SAE Standard establishes minimum requirements for lighting and marking earthmoving construction machinery as defined in SAE J1116, 1.1 Self-Propelled Construction Machines—Earthmoving (excluding excavators). (Construction machinery is normally operated off-highway, and therefore this SAE document is not intended to be used as a basis for regulations by those having authority over on-highway motor vehicles.)

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
