    Abstract - (Show below) - (Hide below)

    Sets out the information to be included for labelling the noise emission of machinery and equipment, and prescribes the manner in which the information is expressed. Identical with and reproduced from ISO 4871:1984.

    Scope - (Show below) - (Hide below)

    This International Standard- prescribes a manner in which the noise emission of machinery and equipment shall be expressed for labelling purposes;- prescribes the minimum information to be given in a label attached to the machine or in commercial or technical documents supplied to consumers by the manufacturer.This International Standard applies to machinery and equipment which is essentially stationary in nature. Traffic vehicles are excluded.It applies only to families of machines or equipment for which measurement test codes for the determination of the sound power level exist.
