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

The cutting edge of the blades shall not extend more than 1,1 mm (see dimension a in Figure Z103) past the surface of the cutter block. Compliance is checked by measurement. 18.1.101.3

There shall be no recess in the cutter block except for the cutting blades and their fastening devices (see Figure Z103). The chip groove in front of the blade shall have a maximum depth (d) measured radially to the cutter block in accordance with Figure Z104. Compliance is checked by inspection and measurement. 18.1.101.4

The blades shall be fixed to the cutter block in such a way that friction alone is not relied upon to prevent ejection of the blades. The clamping screws, if any, shall engage for a minimum of six full threads when fitted to a steel cutter block. When the cutter block is made of material other than steel the clamping arrangement shall have the same degree of strength as that provided by the requirement for the clamping screw for steel block. The cutter block shall ensure that blade(s) are clamped over their total length.

Compliance is checked by inspection and by the following test: The blades are fitted to the cutter block in accordance with the manufacturer’s instructions. The projection of the blades is measured and the cutter block is run at maximum speed nmax for 5 min, after this test the projection of the blades is measured again and the displacement shall not exceed 0,15 mm.

The cutter block is then run at the test speed np for 5 min, the projection of the blades is measured and the displacement from the previous shall not exceed 0,15 mm.
