April 2010 Foreword The text of document 61F/626/FDIS, future edition 2 of IEC 60745-2-15, prepared by IEC SC 61F, (transformed into IEC TC 116, Safety of hand-held motor-operated electric tools), was
14、 submitted to the IEC-CENELEC parallel vote. A draft amendment (prAA), prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116), Safety of hand-held motor-operated electric tools, to bring the European Standard in line with the essential health and safety requirements of the Mach
15、inery Directive, was submitted to the formal vote. The combined texts were approved by CENELEC as EN 60745-2-15 on 2006-05-01. A further draft amendment (prAB), extending Annex ZZ to include the new MD 2006/42/EC, was submitted to the formal vote. The combined texts were approved by CENELEC as a new
16、 edition of EN 60745-2-15 on 2009-06-01. This European Standard supersedes EN 60745-2-15:2006. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2009-12-29 latest date by which
17、the national standards conflicting with the EN have to be withdrawn (dow) 2009-12-29 This standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated tools (for the purpose of this standard referred to simply as tools) which could come
18、within the scope of this standard; Part 2: Requirements for particular types of tools which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these specific tools. This European Standard has been prepared under a mandate given t
19、o CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 98/37/EC (Machinery Directive), amended by EC Directive 98/79/EC and 2006/42/EC. See Annexes ZZA and ZZB. Compliance with the clauses of Part 1 together with this Part 2 pro
20、vides one means of conforming with the essential health and safety requirements of the Directives concerned. CEN/TC 144 is producing standards for non-electric hedge trimmers (EN 774).

The sound power level shall be determined according to 7.1 of ISO 11094, with the measurement surface and six microphone positions specified there. The test environ
41、ment outdoors shall be a flat open space (a slope, if any, not exceeding 5/100), visibly free of sound-reflecting objects (building, trees, poles, sign boards, etc.) within a circular area with a radius equal to approximately three times the radius of the hemispherical measurement surface used. For

However, for outdoor as well as for indoor measurements, the surface of the test environment shall be the artificial surface according to 4.1.2
