Identically adopts ISO 6395:2008, specifying a method for determining the noise emitted to the environment by earth-moving machinery, measured in terms of the A-weighted sound power level while the machine is operating under dynamic test conditions. Applicable to earth-moving machinery as specified in Annex A and as defined in ISO 6165.
This International Standard is a specific test code for earth-moving machinery as defined in ISO 6165.
A simulated dynamic test condition, rather than an actual work cycle, is used. Simulated dynamic test conditions provide 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 International Standard to enable the sound power emission in dynamic test conditions to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer’s production version are intended to be fitted since this is the configuration most likely to exist when the machine is in actual use.
This International Standard enables compliance with noise limits to be determined, if applicable. It can also be used for evaluation purposes in noise reduction investigations.
