14、odifications prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116) was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 60745-2-1 on 2002-12-01. A number of amendments to EN 60745-2-1 have since been voted on and published as amendments A11, A1 an
15、d A12. A further draft amendment (FprAE) including improvements to the vibration test code and some editorial corrections, was submitted to the Unique Acceptance Procedure. The combined texts were approved by CENELEC as a new edition of EN 60745-2-1 on 2010-02-01. This European Standard supersedes E

17、date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2011-02-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2013-02-01 This standard is divided into two parts: Part 1:
18、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 this standard; Part 2: Requirements for particular types of tools which either supplement or modify the requiremen
19、ts 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 CEN and CENELEC by the European Commission and the European Free Trade Association and supports the essential health and safety requ
20、irements of the Machinery Directive 2006/42/EC. See Annex ZZ. Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with the essential health and safety requirements of the Directive concerned. CEN/TC 255 is producing standards for non-electric drills and t
21、appers (EN 792-3) and for non-electric rotary percussive tools (EN 792-5). Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard. This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2
22、-1 is to be used in conjunction with EN 60745-1:2009. When this standard states “addition“, “modification“ or “replacement“, the relevant text in Part 1 is to be adapted accordingly. Subclauses and figures which are additional to those in Part 1 are numbered starting from 101. Annexes, subclauses, t
23、ables and figures which are additional to those in IEC 60745-2-1 are prefixed “Z”.
