19、flicting with the EN have to be withdrawn (dow) 2011-04-01 This standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated tools (for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 this s
20、tandard; 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 European
21、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 provid
22、es 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 stand
23、ard. This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.
