Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Esch member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern- mental and non-governmental, in liaison with ISO, also take patt in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 7574/3 was prepared by Technical Committee ISO/TC 43, A cous tics. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. 0 International Organkation for Standardkation, 1985 l Printed in Switzerland SIST EN 27574-3:1997

INTERNATIONAL STANDARD ISO 7574/3-1985 (EI Acoustics - Statistical methods for determining and verifying stated noise emission values of machinery and equipment - Part 3 : Simple (transition) method for stated values for batches of machines 0 Introduction A general introduction to the four-part series of ISO 7574 is given in ISO 7574/1. For the purposes of this part of ISO 7574, the term “labelled value” Stands for all kinds of stated values (e.g. information on a label, the upper noise limit set by an authority, the agreed contract value) for which the methods may be applied. 1 Scope and field of application This part of ISO 7574 is derived from ISO 7574/4. lt provides guidelines for determining the labelled value, L,, by the labeller and specifies a simple method for verifying compliance of the noise emissions of a batch (lot) of machinery or equipment with its labelled value, L,. This method may be used when a specific noise labelling code (in accordance with clause 6 of ISO 7574/4) specifying the reference Standard deviation, Sample size and sampling procedure for the family of machines does not yet exist. If a specific noise labelling code exists, it shall be used, in which case reference to this part of ISO 7574 shall not be made. This part of ISO 7574 should preferably be used only by agree- ment, e.g. as reached in the Standards relating to the relevant machinery industry or in a contract. This part of ISO 7574 does not deal with the consequences that ensue if the stated value is not confirmed as verified for a batch of machines. 2 References ISO 3741, Acoustics - Determination of Sound power levels of noise sources - Precision methods for broad-band sources in reverbera tion rooms.
