ÖNORM EN ISO 11689

This International Standard 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. NOTE 1 The general procedure described in this Inter-national Standard is, in principle, applicable to other physi-cal agents (e.g. vibration). This International 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. Annex B gives examples of how the evaluation of collected noise-emission data for a machine group can be carried out.
