December 2010 :2009+A1 Foreword The text of the International Standard IEC 60745-2-21:2002, prepared by SC 61F (transformed into IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common modificatio
14、ns prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116), was submitted to the Unique Acceptance Procedure and was approved as EN 60745-2-21 on 2007-05-01. A draft amendment (prAA), extending Annex ZZ to include the new MD 2006/42/EC, was submitted to the formal vote. The comb
15、ined texts were approved by CENELEC as a new edition of EN 60745-2-21 on 2009-07-01. This European Standard supersedes EN 60745-2-21:2007. 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 by endors
16、ement (dop) 2010-05-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2010-05-01 This standard is divided into two parts: Part 1: General requirements which are common to most hand-held electric motor operated tools (for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 re
17、ferred to simply as tools) which could come within 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 Standa
18、rd has been prepared under a mandate given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EC Directive 98/37/EC (Machinery Directive), amended by Directive 98/79/EC, and of EC Directive 2006/42/EC. See Annex ZZA and Annex ZZB. Compl
19、iance with the clauses of Part 1 together with this Part 2 provides one means of conforming with the essential health and safety requirements of the Directives concerned. Warning: Other requirements and other EC Directives can be applicable to the products falling within the scope of this standard.
20、This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2. This Part 2-21 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. Subclauses, tables a
21、nd figures which are additional to those in Part 1 are numbered starting from 101. Subclauses, tables and figures which are additional to those in IEC 60745-2-21 are prefixed “Z”. Annexes ZZA and ZZB have been added by CENELEC. NOTE In this standard the following print types are used: - requirements

NOTE For drain cleaners, no load condition is the worst case for vibration. Typically these tools carry 8 m to 12 m of drain cleaner c

Little or no vibration is transmitted from the cable being in the drain since the drain cleaner cable is basically a large sp
