16、hdrawn (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 within the scope of this standard; Part 2: Requirements for p

17、articular 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 European Commission and the European Free Tr

18、ade Association and covers essential requirements of EC Directives 98/37/EC (Machinery Directive), amended by 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 provides one means of conforming with the essential health and sa

19、fety requirements of the Directives concerned. CEN/TC 144 is producing standards for non-electric chain saws (EN 608). 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

20、 ISO 12100-1 and EN ISO 12100-2. This Part 2-13 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.
