16、ich is held by DIN. 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of an identical text or by endorsement, at the latest by August 2015 and conflicting national standards shall be withdrawn at the latest by August 2015. Attention is drawn to the possib
17、ility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14462:2005+A1:2009. This document has been prepared under a mandate given to CEN by the Eu
18、ropean Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive 2006/42/EC, see informative Annex ZA, which is an integral part of this document. This document includes the following significant technical changes w
19、ith respect to EN 14462:2005+A1:2009: integration of dry ice blasting equipment in A.1.2; integration of automatic electrostatic application equipment for flammable flock material (EN 50223) in A.3.1. It augments the “C”-type safety standards prepared by CEN/TC 271. Its purpose is to provide a means
20、 of determination, declaration and verification of noise emission for the equipment within the scope of this document. The determination of noise emission values is a prerequisite for a manufacturer to assess the noise reduction obtained at the design stage. According to the CEN-CENELEC Internal Reg
21、ulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland,
22、Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 14462:2015EN 14462:2015 (E) 4 Introduction This noise test code gives assistance to carry out noise emission measurements
23、and to determine values for noise declaration purposes under the Machinery Directive 2006/42/EC and provides the means for their verification. Annex D with Figure D.1 and Figure D.2 provides an overview on the noise determination procedure. Noise emission characteristics include both emission sound
24、pressure levels at workstations and sound power levels. The determination of these characteristics is necessary for manufacturers to declare the noise emitted, comparing the noise emitted by machines, purposes of noise control at the source during the design stage, estimation of noise exposure at th
25、e workstation(s). Noise testing of the machinery can be done at the manufacturers site, at the place of mounting or at any other adequate location. BS EN 14462:2015EN 14462:2015 (E) 5 1 Scope This European Standard specifies standardized conditions for the determination, declaration and verification
26、 of airborne noise emission of the following surface treatment equipment: machinery for cleaning and pre-treatment of industrial item surfaces (see EN 12921-1, EN 12921-2, EN 12921-3, EN 12921-4); phosphating machinery; plating machinery; plasma surface treatment machinery; machinery for the supply
27、and/or circulation of coating materials under pressure (see EN 12621, EN 12757-1); atomizing and spraying equipment for coating materials (see EN 1953, EN 50050-1, EN 50050-2, EN 50050-3, EN 50059, EN 50176, EN 50177, EN 50348); coating plants (see EN 12215, EN 12581, EN 12981, EN 13355, EN 50223);
28、dryers, ovens and evaporating equipment (see EN 1539); thermal cleaning plants (incinerators) for exhaust gas from surface treatment plants (see EN 12753); dry-ice blasting equipment. For the above surface treatment machinery, this European Standard gives provisions for the determination of emission
29、 sound pressure levels at workstations and/or other specified positions and sound power levels. This European Standard specifies noise emission measurement methods, mounting and operating conditions that shall be used for the test. The use of this document ensures the reproducibility of the determin
30、ation of the noise emission characteristics within specified limits determined by the grade of accuracy of the basic noise emission measurement method used (see Clause 4 and Clause 5). Noise emission measurement methods allowed by this document are engineering methods (grade 2) and survey methods (g
31、rade 3). This European Standard does not apply to machines not explicitly listed in the scope: printing, paper converting and paper making machinery and auxiliary equipment (see EN 13023); abrasive blasting machinery see EN 1265. 2 Normative references The following documents, in whole or in part, a
