15、00 2006, Uncontrolled Copy, (c) BSI EN 50260-1:2002- 2 - Foreword This European Standard has been prepared by the Technical Committee CENELEC TC 61F, Hand-held and transportable electric motor-operated tools. A first draft was submitted to the Unique Acceptance Procedure in August 1996 with positive
16、 results. A second draft incorporating the editorial comments received during the UAP and the modifications necessary to incorporate the mechanical requirements which have been agreed for hand-held tools, was submitted to the formal vote in November 1999 and was approved on 2000-08-01. Based on comm
17、ents received from directive consultants, a further draft was submitted to a 2 months vote and was approved by CENELEC as EN 50260-1 on 2002-03-05. The following dates were fixed: -latest date by which the EN has to be implemented at national level by publication of an identical national standard or
18、 by endorsement(dop)2003-03-01 -latest date by which the national standards conflicting with the EN have to be withdrawn(dow)2005-03-01 Other standards referred to in this European Standard are listed in annex F. The annex lists the valid edition of those documents at the time of issue of this EN. A
19、ll references are however to be understood as references to the latest edition. This European Standard is divided into two parts: Part 1:General requirements which are common to most hand-held battery powered motor operated tools (for the purpose of this European Standard referred to simply as tools
20、). 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 specific tools. This European Standard has been prepared under a mandate given to CEN and CENELEC by the European
21、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 a relevant Part 2 of this standard provides one means of conforming with the essential health and safety requir
22、ements of the Directive. A relevant Part 2 is one in which the type of the tool or an accessory which is to be used with the tool is within the scope of that Part 2. When a relevant Part 2 does not exist, Part 1 can help to establish the requirements for the tool, but will not by itself provide a me
23、ans of conforming with the relevant essential health and safety requirements of the Machinery Directive. Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard. Hand held motor-operated tools are covered by the EN 50144 series.
24、 In order to be consistent with the EN 50144 series, the same order of clauses has been kept; the missing clauses are considered void. CEN Technical Committees have produced a range of standards dealing with a similar range of non- electrically powered tools. Where necessary normative references are
25、 made to these standards in the relevant Part 2. This standard follows the overall requirements of EN 292-1 and EN 292-2. NOTE In this standard the following print types are used: -Requirements proper; -Test specifications; -Explanatory matter. Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 06

30、 50260-1:2002 1Scope This standard applies to hand-held rechargeable battery-powered, motor-operated or magnetically driven tools intended for indoor or outdoor use designed for use by one person and the battery packs for such tools including those intended to be charged from chargers with a non-iso
31、lated output with an output voltage of not more than 250 volts. Battery operated tools which can be operated while connected to the mains shall also comply with EN 50144-1. This Part 1 is to be used in conjunction with the appropriate Part 2, which contains clauses which supplement or modify the cor
32、responding clauses in Part 1 to provide the complete requirement for each sort of tool. It also applies, as far as is reasonable, to tools not mentioned in Part 2 and to those designed on basically new principles in which case additional requirements may be necessary. This standard covers tools whic
33、h can be used in a fixed support. Unless the requirement for such a support is given in a relevant Part 2, this standard alone will not be sufficient to ensure that the combination of tool and support is adequate. Tools or battery packs incorporating battery chargers are also within the scope of thi
34、s standard but such tools and packs are also required to comply with EN 60335-2-29. This standard does not apply to: -tools used for preparing or processing food; -tools used in explosive atmospheres. It does not apply to a general purpose battery that may be purchased and installed by the user. It
35、does not apply to battery chargers. Battery chargers with an output at safety extra-low voltage are covered by EN 60335-2-29. 2Definitions 2.1 (hand-held) tool battery powered motor-operated or magnetically driven machine intended to do mechanical work and so designed that the motor and the machine
