2014-02-14 This European Standard is divided into two parts: Part 1 General requirements that are common to most transportable electric 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 for the particular hazards and characteristics of these specific tools. This European Standard has been prepared under Mandate M/396 given to CENELEC by the European Commission and the European Free Trade Association and covers essential requirements of EU Directive 2006/42/EC. See Annex ZZ. Compliance with the relevant clauses of Part 1 together with this Part 2-3 provides one means of conforming with the specified essential requirements of the Directives. The requirements defined in EN ISO 12100 are also dealt with in this European Standard. For noise and vibration this European Standard covers the requirements 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 given as this reflects the current state of the art.
Warning: Other requirements arising from other European Directives can be applicable to the products falling within the scope of this European Standard. This Part 2-3 is to be used in conjunction with EN 61029-1:2009. This Part 2-3 supplements or modifies the corresponding clauses of EN 61029-1, so as to convert it into the European Standard: “Safety of transportable motor-operated electric tools – Part 2-3: Particular requirements for planers and thicknessers”. Where a particular clause or subclause of Part 1 is not mentioned in this Part 2-3, that clause or subclause applies as far as is reasonable. Where this Part 2-3 states "addition", "modification" or "replacement", the relevant text of Part 1 is to be adapted accordingly. SIST EN 61029-2-3:2011
