This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by March 1999 and conflicting national standards shall be withdrawn at the latest by March This European Standard has been prepared by Technical Committee CEN/TC 211 "Acoustics", the Secretariat of which is held by Denmark, as a guidance document to be used by CEN machinery Technical Committees as the basis for the preparation of the clauses concerning noise in their type C-Standards. "Guidance" is used, because the document is a general one and therefore may not be applicable in all details for a specific type of machinery. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). Several documents concerning noise referred to in this European Standard are at the moment at the stages of draft. The latest reference document numbers are given which makes it possible to obtain these documents from a national member body. This European Standard also contains two annexes which are informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

6 Page 3 Provläsningsexemplar / Preview Introduction For many machines, noise is a significant hazard, i.e. a hazard which an assessment carried out in accordance with EN 1050 has lead to identify as being connected with one or more essential requirements decreed in annex I of the Machinery Directive and which requires a specific action on the part of the manufacturer or supplier (see of EN 414:1992). The information contained in this European Standard is based on the following principles: a) noise reduction is an integral part of machinery safety, and b) machinery must be so designed and constructed that risks resulting from the emission of airborne noise are reduced to the lowest level taking account of technical progress and available means of reducing noise, in particular at source, and c) specific quantitative information on airborne noise emitted by machinery under specified operating and mounting conditions shall be given in accordance with the relevant noise test code, or, if no test code exists, under specified individual conditions. d) the noise clauses of type C-Standards shall deal with noise emission aspects including residual risk; but information on how the noise immission at the work station can be further reduced, including advice on personal protection equipment, may be helpful. 1 Scope This European Standard gives guidance on how to deal with noise in type C- Standards where noise is identified as a significant hazard (see 4.5 of EN 292-1: 1991). As such, this European Standard supplements the rules given in EN 414: The exact way that noise is dealt with for a particular type of machinery will depend on the structure of the type C-Standards and is the responsibility of the type C-Standard Technical Committees. 2 Normative references This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

7 Provläsningsexemplar / Preview Sida 3 Inledning Buller utgör en väsentlig potentiell risk vid många maskiner. En uppskattning gjord i enlighet med EN 1050 visar att en sådan risk kan kopplas samman med ett eller flera av de grundläggande kraven i annex 1 i Maskindirektivet, som kräver specifika åtgärder från tillverkarens eller leverantörens sida (se i EN 414:1992). Informationen i denna Europastandard baseras på följande principer: a) bullerbekämpning är en nödvändig del i maskinsäkerhetsarbetet; b) maskiner måste vara utformade och konstruerade så att risker som härrör från emissionen av luftburet buller är minskat till en lägsta nivå med hänsyn tagen till tekniska framsteg och till tillgängliga hjälpmedel för att reducera buller, speciellt vid källan; c) exakt information om det som erhålles under noggrant angivna drifts- och uppställningsförhållanden skall ges i enlighet med den produktspecifika bullermätmetoden, eller om ingen sådan mätmetod skulle finnas, skall de under rådande omständigheterna vid mätningen anges; d) paragraferna som behandlar buller i C-standarder skall innehålla bulleremissionsaspekter inklusive kvarvarande risk, men också information, om hur bullerimmission vid arbetsplatsen kan minskas ytterligare, kan vara till hjälp, inklusive råd om personlig skyddsutrustning. 1 Omfattning Denna Europastandard ger riktlinjer för hur buller ska behandlas i C-standarder där buller uppfattas som en betydande risk (se 4.5 i EN 292-1:1992). Denna standard fungerar som ett tillägg till reglerna i EN 414:1992. Det sätt på vilket buller behandlas vid en speciell maskintyp, beror på strukturen hos C-standarden och ansvaret ligger hos de tekniska kommittéerna för respektive C-standard 2 Normativa hänvisningar Denna standard innehåller daterade eller odaterade hänvisningar till regler i andra publikationer.
