16、al Standard is a specific noise test code for forestry machinery mentioned in the scope of this International Standard and as defined in ISO 6814.A simulated dynamic test condition, rather than an actual work cycle, is used. Simulated dynamic test conditions provide noise emission data which are rep
17、eatable and representative. Actual work cycle tests are complex and repeatability can be a problem.This International Standard may also be used to determine noise emission for each part of the simulated work cycle.Specific procedures are described in this International Standard to enable the sound p
18、ower level and the emission sound pressure level in dynamic test conditions to be determined in a manner which is repeatable. This International Standard enables compliance with noise limits to be determined, if applicable. It can also be used for evaluation purposes in noise reduction investigation

ISO 2016 All rights reserved vBS ISO 18564:2016BS ISO 18564:2016Machinery for forestry Noise test codeCAUTION The test method specified in this International Standard may lead to a hazardous situation due to moving and rotating machine parts. Test personnel shall stay in safe zones when measuring
20、 and observing the tests.1 ScopeThis noise test code specifies all the information necessary for carrying out efficiently and under standardised conditions the noise emission values of self-propelled forestry machinery. It is applicable to fellers, bunchers, delimbers, forwarders, log loaders, skidd
21、ers, processors, harvesters, mulchers and multi-function versions of these machine types, as defined in ISO 6814.Noise emission characteristics include A-weighted emission sound pressure values at the operators station and the A-weighted sound power value. The determination of these quantities is ne
22、cessary for the following: manufacturers to declare the noise emitted; comparing the noise emitted by machines in the family concerned; purposes of noise control at the source at the design stage.NOTE For low-noise design, noise emission values in frequency bands are useful and the basic Internation
23、al Standards ISO 3744 and ISO 11201 can be used for determining noise emission quantities in frequency bands.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
