14、as approved by CENELEC as EN 60745-2-9 on 2003-02-01. A draft amendment (prAB) was prepared to align Subclause 6.2 with the new Subclause 6.2 in EN 60745-1. Moreover, vibration values determined with the new 6.2 are complying with the requirements of the Physical Agents Directive Vibration 2002/44/E
15、C. The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as amendment A11 to EN 60745-2-9:2003 on 2007-06-01. The text of document 61F/674/CDV, future amendment 1 to IEC 60745-2-9:2003, was submitted to the IEC-CENELEC parallel Unique Acceptance Procedure
16、 and was approved by CENELEC as amendment A1 to EN 60745-2-9:2003 on 2008-04-01. A further draft amendment (prAC), 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 edition of EN 60745-2-9 on 2009-07-01. This E
17、uropean Standard supersedes EN 60745-2-9:2003 + A11:2007 + A1:2008. 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) 2010-07-01 - latest date by which the national standards
18、conflicting with the EN have to be withdrawn (dow) 2011-04-01 This standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated tools (for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 within the scope of thi
19、s 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 to CENELEC by the Europe
20、an Commission and the European Free Trade Association and supports the essential requirements of EC Directive 98/37/EC (Machinery Directive), amended by EC Directive 98/79/EC, and of EC Directive 2006/42/EC. See Annexes ZZA and ZZB. Compliance with the clauses of Part 1 together with this Part 2 pro
21、vides one means of conforming with the essential health and safety requirements of the Directive concerned. CEN/TC 255 is producing standards for non-electric tappers (EN 792-3). Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this st
22、andard. This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. BS EN 60745-2-9:2009- 2 -EN 60745-2-9:2009 (E)This Part 2-9 is to be used in conjunction with EN 60745-1:2009.

23、 1 is to be adapted accordingly. Subclauses and figures which are additional to those in Part 1 are numbered starting from 101. Subclauses, tables and figures which are additional to those in IEC 60745-2-9 are prefixed “Z”. NOTE In this standard, the following print types are used: - requirements: i
