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 carrying out a simulated work cycle. 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. A simulated rather than an actual work cycle test condition is chosen. Simulated work cycles provide acceptable noise emission data which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem. Specific procedures are described in this document to enable the sound pressure level at the operator's position,with the machine in a simulated work cycle test condition, to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version are to be fitted since this is the configuration most likely to exist when the machine is in actual use. This document enables compliance with noise limits to be determined. It can also be used for evaluation purposes in noise reduction investigations. An additional special test code is given in SAE J2104/ISO 6395. This other special test code is intended to be used to determine the noise emitted by earthmovign machinery in terms fo the A-weighted sound power level while the machine is in a simulated work cycle test condition. Corresponding measurements of exterior noise and noise at the operator's position under stationary test conditions are described in SAE J2102/ISO 6393 and ISO J2103/ISO 6394, respectively.
