Acoustics — Statistical methods for determining and verifying stated noise emission values of machinery and equipment, Part 4: Methods for stated values for batches of machines

This method provides guidelines for determining noise emission values of machinery and equipment for those labelling the devices, and specific statistical sampling procedures for verifying compliance of the noise emissions of a batch of equipment. Identical with and reproduced from ISO 7574-4:1985.
