TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY – SAFETY – Part 2-14: Particular requirements for hand-held planers FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62841-2-14 has been prepared by IEC technical committee 116: Safety of motor-operated electric tools. The text of this standard is based on the following documents: FDIS Report on voting 116/222/FDIS 116/236/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This Part 2-14 is to be used in conjunction with the first edition of IEC 62841-1 (2014). This Part 2-14 supplements or modifies the corresponding clauses in IEC 62841-1, so as to convert it into the IEC standard: Particular requirements for hand-held planers. Where a particular subclause of Part 1 is not mentioned in this Part 2-14, that subclause applies as far as relevant. Where this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. The following print types are used: – requirements: in roman type; – test specifications: in italic type; – notes: in small roman type. The terms defined in Clause 3 are printed in bold typeface. Subclauses, notes and figures which are additional to those in Part 1 are numbered starting from 101. A list of all parts of the IEC 62841 series, under the general title: Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be • reconfirmed, • withdrawn, • replaced by a revised edition, or • amended. A bilingual version of this publication may be issued at a later date. NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 36 months from the date of publication. --`,```,``,,`,,`,,,,``,,`,```,,`-`-`,,`,,`,`,,`--- ELECTRIC MOTOR-OPERATED HAND-HELD TOOLS, TRANSPORTABLE TOOLS AND LAWN AND GARDEN MACHINERY – SAFETY – Part 2-14: Particular requirements for hand-held planers Scope This clause of Part 1 is applicable, except as follows: Addition: This part of IEC 62841 applies to planers.

Compliance is checked by a new tool sample completing the following test. The planer is to be set in horizontal position. The lift-off device is cycled through its intended range of operation for 50 000 cycles. This sequence is repeated at a rate not less than 10 cycles per minute. After completion of the cycling test as specified above, the planer shall then comply with 19.111. 18 Abnormal operation This clause of Part 1 is applicable, except as follows: 18.8 Replacement of Table 4 by the following: Table 4 – Required performance levels Type and purpose of SCF Minimum Performance Level (PL) Power switch – prevent unwanted switch-on c Power switch – provide desired switch-off for planers with lift-off device a Power switch – provide desired switch-off for planers without lift-off device b Any electronic control to pass the test of 18.3 a Overspeed prevention to prevent output speed above 130 % of rated no-load speed b Provide desired direction of rotation a Prevent exceeding thermal limits as in Clause 18 a Prevent self-resetting as required in 23.3 b Lock-off function as required by 21.18.1.2 b 19 Mechanical hazards This clause of Part 1 is applicable, except as follows: 19.1 Addition: For the requirements given in 19.107, 19.108 and 19.109, only the test probe shown in Figure 102 is used. 19.4.101 Planers with a mass according to 5.17 exceeding 3 kg shall have at least two handles. The auxiliary handle, if any, may also be used for the depth-of-cut setting, provided the adjustment of depth of cut is achieved by a rotary action. Compliance is checked by inspection and by measurement. 19.101 The cutting head shall be cylindrically shaped except for the blades, the gullet and the blade clamping means. The maximum gullet width s shall be smax = 0,235 d + 7,2 mm where d is the diameter of the rotating circle of the cutting edges. See Figure 101. Compliance is checked by inspection and by measurement. 19.102 The blades when aligned with the fixed shoe shall not project by more than 1,1 mm radially beyond the cutter block (as per dimension “a” in Figure 101). Compliance is checked by measurement. 19.103 At any depth of cut, the distance “b” (see Figure 101) between the rotating circle of the cutting edges and the trailing edge on the adjustable shoe shall not exceed 5 mm measured radially. Compliance is checked by inspection and by measurement. 19.104 The blades shall be secured in the cutter block in such a way that friction alone is not relied upon to prevent the radial ejection of the blades. Compliance is checked by inspection. 19.105 Cutting heads shall be designed and made of such materials that they withstand the forces and loads expected in normal use. Compliance is checked by the following test: An overspeed test shall be made on a sample cutting head, equipped with blades for the largest cutting diameter and the largest cutting edge width, the test speed being 1,5 times the rated no-load speed. If applicable, tension elements such as clamping screws shall be tightened in accordance with the instructions required by 8.14.2 b). After the test, the cutting head shall not be deformed or cracked, no screws shall be loosened and displacements of separable parts shall be less than specified in the test procedure. The test procedure is as follows: 1) Measure the cutting head dimensions. 2) Bring the cutting head to the rated no-load speed, for 1 min. 3) Stop and re-measure the cutting head; measured displacements of the separable parts of the cutting head shall not be greater than 0,15 mm. 4) Bring the cutting head to the test speed, for 1 min. 5) Stop and re-measure the cutting head and compare the results with those obtained from step 3. The compared displacements shall not exceed 0,15 mm. 19.106 Clamping screws or bolts shall not project beyond the cutter block as shown in Figure 101. Compliance is checked by inspection. 19.107 It shall not be possible to inadvertently touch rotating parts from the sides of the planer, except for the cases covered by 19.108. Compliance is checked by the following test: The planer is set to minimum depth of cut and is positioned with the shoes resting on a flat surface that extends beyond the planer by at least 100 mm in all directions. Any lift-off device is disabled. The accessibility is checked by means of the test probe shown in Figure 102 with a force not exceeding 5 N. 19.108 Planers with rabbeting facilities shall be provided with a guard that avoids inadvertent contact at the sides with the blades. NOTE Rabbeting is also known as rebating. Compliance is checked by inspection and by the following test: The planer is set to minimum depth of cut and is positioned with the shoes resting on a flat surface that extends beyond the planer by at least 100 mm in all directions. Any lift-off device is disabled. The accessibility is checked by means of the test probe shown in Figure 102 without any force. 19.109 It shall not be possible to touch the blades through the chip ejection opening. Compliance is checked by testing all apertures for chip ejection with the test probe of Figure 102. It shall not be possible to touch the blades in the cutting head at any angle of the probe. 19.110 Planers shall stop within 10 s after switching off. Compliance is checked by inspection and by measurement. 19.111 Lift-off device 19.111.1 If a lift-off device is provided to meet the requirements of 18.8 or 21.18.1.1, it shall meet the requirements of 19.111.2 and 19.111.3, which are checked only after completing the endurance test of 17.101. 19.111.2 If a lift-off device is provided, it shall be designed so that – it is automatically activated, when the planer is lifted up from a horizontal surface; and – the blade(s) do not make contact, when the planer is set at maximum depth of cut in accordance with 8.14.2 b) 101) and placed on a horizontal surface. Compliance is checked by inspection. 19.111.3 A lift-off device shall provide sufficient stability. Compliance is checked by the following test: The planer is set to maximum depth of cut in accordance with 8.14.2 b) 101) and with the supply cord, if any, removed. The planer is then placed on a flat board of medium density fibreboard (MDF) having a density of 650 kg/m3 to 850 kg/m3 that is inclined at an angle of 10°, such that the rear of the planer is nearest to the high side of the board and allowed to rest freely for 10 s to 12 s. During the test, the planer is permitted to slide, however, the lift- off device shall not collapse such that the planer blades come into contact with the board. 20 Mechanical strength This clause of Part 1 is applicable. 21 Construction This clause of Part 1 is applicable, except as follows: 21.18.1.1 Addition: Planers whose blade(s) make contact with a flat surface when the base plate is placed on the flat surface and without a lift-off device are regarded as tools having a risk associated with continued locked-on operation. NOTE In Europe (EN 62841-2-14), the above text is replaced by the following: For planers, the switch shall not have any locking device to lock it in the “on” position. 21.18.1.2 Addition: Planers are regarded as tools having a risk associated with inadvertent starting. 21.35 This subclause of Part 1 is applicable. 22 Internal wiring This clause of Part 1 is applicable. 23 Components This clause of Part 1 is applicable. 24 Supply connection and external flexible cords This clause of Part 1 is applicable. 25 Terminals for external conductors This clause of Part 1 is applicable. 26 Provision for earthing This clause of Part 1 is applicable. 27 Screws and connections This clause of Part 1 is applicable. 28 Creepage distances, clearances and distances through insulation This clause of Part 1 is applicable. a) Example 1 and explanation of basic dimensions b) Example 2 Key fixed shoe adjustable shoe trailing edge a radial projection of the blades beyond the cutter block b distance between the rotating circle of the cutting edges and the trailing edge of the adjustable shoe d diameter of the rotating circle of the cutting edges s gullet width Figure 101 – Examples of cutting heads with basic dimensions IEC IEC --`,```,``,,`,,`,,,,``,,`,```,,`-`-`,,`,,`,`,,`--- ∅35±0,2 ∅8 Key handle section test section probe’s flange Dimensions in millimetres −0,05 ∅12 +0 R6 +0 −0,05 50±0,2 IEC Figure 102 – Test probe Annexes The annexes of Part 1 are applicable except as follows.
