16、l Committee CENELEC TC 61F, Hand-held and transportable electric motor operated tools. The text of the draft was submitted to the Unique Acceptance Procedure (UAP) in December 1993 and was approved by CENELEC as EN 50144-2-10 on 1994-10-04. A draft for an amendment was submitted to UAP in April 1994
17、 and was approved by CENELEC on 1994-10-04 for inclusion into the European Standard. A further amendment was submitted to UAP in May 1996 and was approved by CENELEC as amendment A1 to EN 50144-2-10 on 1996-12-09. Amendments to fulfill the essential requirements of the Machinery Directive were submi
18、tted to the formal vote in June 1998 and were approved by CENELEC on 1998-10-01 for inclusion, together with the earlier amendment, into a second edition of EN 50144-2-10. This European Standard supersedes EN 50144-2-10:1996. The following dates were fixed: -latest date by which the EN has to be imp
19、lemented at a national level by publication of an identical national standard or by endorsement(dop)2001-09-01 -latest date by which the national standards conflicting with the EN have to be withdrawn(dow)2001-12-01 This standard is divided into two parts: Part 1: General requirements which are comm
20、on to most hand-held electric motor operated tools (for the purpose of this standard referred to simply as tools). Part 2: Requirements for particular types of tool which either supplement or modify the requirements given in Part 1 to account for the particular hazards and characteristics of these s
21、pecific tools. This European Standard has been prepared under a mandate given to CEN/CENELEC by the European Commission and the European Free Trade Association and supports the essential health and safety requirements of the Machinery Directive. Compliance with the clauses of Part 1 together with th
22、is Part 2 provides one means of conforming with the essential health and safety requirements of the Directive. For noise and vibration this standard covers the requirements for their measurement, the provision of information arising from these measurements and the provision of information about the
23、personal protective equipment required. Specific requirements for the reduction of the risk arising from noise and vibration through the design of the tool are not given as this reflects the current state of the art. As with any standard, technical progress will be kept under review so that any deve
24、lopments can be taken into account. CEN TC/255 is producing standards for non-electrically powered tools. 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 292-1 and EN
25、292-2. Subclauses, tables and figures which are additional to those in Part 1 are numbered starting from 101.
