12、N 61029-2-1:2010 2 Foreword The text of the International Standard IEC 61029-2-1:1993 and its amendments 1:1999 and 2:2001, prepared by SC 61F (transformed into IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common modifications prepared by the Technical Committee
13、CENELEC TC 116, former TC 61F, Safety of hand-held motor-operated electric tools, was submitted to the formal vote and was approved by CENELEC as EN 61029-2-1 on 2001-12-01. A draft amendment (prAA), extending Annex ZZ to include the new MD 2006/42/EC, was submitted to the formal vote. The combined
14、texts were approved by CENELEC as a new edition of EN 61029-2-1 on 2009-11-17. This European Standard supersedes EN 61029-2-1:2002 + corrigendum January 2003. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall n
15、ot be held responsible for identifying any or all such patent rights. 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 endorsement (dop) 2010-06-01 - latest date by which the national standard
16、s conflicting with the EN have to be withdrawn (dow) 2010-06-01 In this European Standard the common modifications to the International Standard are indicated by a vertical line in the left margin of the text. This standard is divided into two parts: Part 1 General requirements, which are common to
17、most transportable motor, operated tools (for the purpose of this European Standard referred to simply as tools) which could come within the scope of this European Standard. Part 2 Requirements for particular types of tool which either supplement or modify the requirements given in Part 1 to account
18、 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 Trade Association and covers essential requirements of EC Directive 2006/42/EC. See Annex ZZ. Compliance
19、 with the relevant clauses of Part 1 together with this Part 2 provides one means of conforming with the specified essential health and safety requirements of the Directive. The requirements defined in EN 1050 are also dealt with in this standard. For noise and vibration this standard covers the req
20、uirements for their measurement, the provision of information arising from these measurements and the provision of information about the 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
21、 given as this reflects the current state of the art. Warning: Other requirements arising from other EC Directives can be applicable to the products falling within the scope of this standard. BS EN 61029-2-1:2010 3 EN 61029-2-1:2010 This Part 2-1 is to be used in conjunction with EN 61029-1:2009. Th
22、is Part 2-1 supplements or modifies the corresponding clauses of EN 61029-1, so as to convert it into the European Standard: “Safety requirements for transportable circular saw benches“. Where a particular subclause of Part 1 is not mentioned in this Part 2-1, that subclause applies as far as is rea
23、sonable. Where this Part 2-1 states “addition“, “modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. Clauses, subclauses, notes, tables and figures which are additional to those in Part 1 are numbered starting from 101. Clauses, subclauses, notes, tables and fig
24、ures which are additional to those in IEC 61029-2-1 are prefixed “Z”. NOTE In this standard the following print types are used: - requirements proper: in roman type; - test specifications: in italic type; - explanatory matter: in smaller roman type.
