This European Standard has been prepared by Technical Committee CEN/TC 211, Ac
16、oustics, 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 a

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
18、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 Inte
19、rnal 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
20、 and the United Kingdom. Page 3 EN 1746:1998 BSI 02-1999 Introduction For many machines, noise is a significant hazard, i.e. a hazard which an assessment carried out in accordance with EN 1050 has led to identify as being connected with one or more essential requirements decreed in annex I of the Ma
21、chinery Directive and which requires a specific action on the part of the manufacturer or supplier (see EN 414:1992, 6.4.2). 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
22、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 un
23、der 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
24、on how the noise emission 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 EN 292-1:1991, 4
