scope:

Specifies a method for establishing the noise-control performance for a family, type, group or sub-group of machinery or equipment on the basis of noise-emission data. It is in principle, applicable to any kind of machinery or equipment for which a noise test code exists or comparable noise-emission data are available. This Standard specifies methods and requirements for comparison of noise-emission data so that they can be used for the determination of noise-control performance. The methods presented allow evaluation of the noise emission of individual machines or of a single type of machine within a machine group, i.e. allow a comparison of the acoustical aspects of machines with comparable non-acoustical data and fields of application.
