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

Stability test for bridge type guards For the following tests, the bridge is set to its low position and to a position where it covers the full width capacity of the machine, unless otherwise specified. ZA.1 Deflection of the bridge support A test force F of 80 N is applied in accordance with Figure ZA.2 to the bridge support, parallel to the cutter block rotational axis. The deflection "a" is measured along the same axis as that of force F. ZA.1.1 Test method Take up any free play in the assembly by applying a force of 20 N to the bridge support in the opposite direction to force F. The position reached will be the origin for measurement. Remove the force. Apply and remove a force of 50 N to the bridge support in the direction of F. Measure the play (deviation from the origin). Apply a test force F = 80 N to the bridge support and measure the deflection "a". ZA.1.2 Test result After the force is released, the guard support should return to the rest position obtained in ZA.1.1, second paragraph. The guard passes the test, if the requirements of the Figure ZA.2 are met. ZA.2 Measuring the free play of the bridge in its support Lock the bridge in position using the device designed for this purpose. Apply to the bridge forces F1 and F2 of 7 N parallel to the tables in a plane perpendicular to the cutter block rotational axis at a point located at 10 mm from the end of the bridge.
The deflection "b" is measured at the application point of force F1 or F2, see Figure ZA.3. ZA.2.1 Test method Apply and remove force F1. The bridge position reached will be the origin for measurements. Apply and remove the force F2. Measure the free play "b" (deviation from the origin). ZA.2.2 Test result The guard passes the test, if the requirements of Figure ZA.3 are met. ZA.3 Bridge blockage Lock the bridge in position using the device designed for this purpose.

– 29 – EN 61029-2-3:2011 A test force F3 of 80 N is applied to the bridge as shown in Figure ZA.2. The direction of F3 is the same as for F (see ZA.1). The bridge shall not slide in its support. ZA.4 Friction test The test only applies, if the guard is equipped with a device that automatically returns the bridge to its preset position. Adjust the guard to be in a position at approximately half the maximum work piece height capacity of the machine. Friction is considered to be correctly adjusted at delivery. ZA.4.1 Test method Note the position of the control lever. Manually push the bridge vertically until it comes into contact with the tables. Release the bridge. Let it return to the position to which it was initially adjusted and monitor the position of the lever after release. Carry out the manoeuvre five times. Check the position of the lever. ZA.4.2 Test result The guard passes the test, if upon release the position of the control lever has not changed. ZA.5 Ergonomic characteristics The force necessary to move the bridge in its support
