Earth-moving machinery. Determination of sound power level. Dynamic test conditions Ingestion-build-279162 Why should you use PD1 Scope This International Standard specifies 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. It is applicable to earth moving machinery as specified in Annex A and as defined in ISO 6165.
