27、ic tools, was submitted to the formal vote and was approved as EN 60745-2-3:2011 on 2011-02-01. This European Standard supersedes EN 60745-2-3:2007 + A11:2009. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall
28、not be held responsible for identifying any or all such patent rights.

29、dards conflicting with the amendment have to be withdrawn (dow) 2014-02-01 This European Standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated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 w
30、ithin 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 Mandate 396 given
31、to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 2006/42/EC. See Annex ZZ. Compliance with the clauses of Part 1 together with this Part 2-3 provides one means of conforming with the essential health and safety requiremen
32、ts of the Directive concerned. Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard. CEN/TC 255 is producing standards for non-electric grinders (EN 792-7), polishers and sanders (EN 792-8) and die grinders (EN 792-9). This E
33、uropean Standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-3 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. BS EN 60745-2-3:20
