ISO International Standard

ISO 6394:2008 specifies a method for determining the emission sound pressure level of earth-moving machinery at the operator’s position, measured in terms of the time-averaged A-weighted emission sound pressure level while the machine is stationary with the engine operating at the rated speed under no-load condi­tions.

It is applicable to earth-moving machinery as defined in ISO 6165 and specified in ISO 6393:2008, Annex A.
