EN 1547:2001+A1:2009 (E) 4 Introduction This standard has been prepared to be a harmonized standard to provide one means of conforming with the essential safety requirements of the Machinery Directive and associated EFTA Regulations. This European Standard is a type C-Standard as defined in !EN ISO 12100". This noise test code provides manufacturers and third parties with the means to carry out noise emission measurements, determine values for noise declaration purposes and verify declared values. The determination of noise emission requires manufacturers to acquire a basic technical know-how regarding noise emission metrology. This explains the approach taken in the body of the standard for the determination of the sound power level. 1 Scope !This noise test code specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the noise emission characteristics of industrial thermoprocessing equipment as described especially in EN 746-1, EN 746-2 and EN 746-3. It also indicates the location of work stations where measurements need to be made." Noise emission characteristics include emission sound pressure levels at work stations and the sound power level. The determination of these quantities is necessary for: manufacturers to declare the noise emitted; comparing the noise emitted by machines in the group concerned; purposes of noise control at the source at the design stage. The use of this standard ensures the reproducibility of the determination of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise measurement method used. Noise measurement methods allowed by this standard are engineering methods (grade 2) and survey methods (grade 3). This standard does not cover the computation of personnel daily noise exposure. 2 Normative references !The following referenced documents are indispensable for the application of this document.
