13、E) 3 European foreword This document (EN 50632-3-3:2017) has been prepared by CLC/TC 116 “Safety of motor-operated electric tools”. The following dates are fixed: latest date by which the EN has to be implementedat national level by publication of an identicalnational standard or by endorsement(dop)
14、 2017-11-14 latest date by which the national standards conflictingwith the EN have to be withdrawn(dow) 2018-11-14 This European Standard is divided into three parts: Part 1: General requirements for the dust measurement which are common to electric motor-operated tools (for the purpose of this sta
15、ndard referred to simply as tools); Part 2 or 3: Requirements for the dust measurement for particular types of tools, which either supplement or modify the requirements given in Part 1 to account for the particular characteristics of these specific tools. This Part 3 is to be used in conjunction wit
16、h EN 50632-1:2015. This Part 3 supplements or modifies the corresponding clauses in EN 50632-1:2015. This Part 3 was developed to set out requirements for the measurement of the concentration for inhalable and respirable dust emitted by transportable planers and thicknessers. Where a particular subc
17、lause of Part 1 is not mentioned in this Part 3, that subclause applies as far as reasonable. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted accordingly. Subclauses, tables and figures which are additional to those in Part 1 are nu
18、mbered starting from 101. This European Standard has been drafted in accordance with the CEN/CENELEC Internal Regulations, Part 3. The following print types are used: requirements proper: in roman type; test specifications: in italic type; explanatory matter: in smaller roman type. The terms defined
19、 in Clause 3 are printed in bold typeface. BS EN 50632-3-3:2017EN 50632-3-3:2017 (E) 4 1 Scope This clause of Part 1 is applicable, except as follows: Addition: This part of EN 50632 applies to transportable planers and thicknessers intended to plane wood. Normative references This clause of Part 1
20、is applicable. Terms and definitions This clause of Part 1 is applicable, except as follows: 3.101 planer tool designed to plane the surface of wood by means of a cutter block rotating about a horizontal axis and located between two frames used to position and support the workpiece Note 1 to entry:
21、The lower surface of the workpiece is planed. 3.102 thicknesser tool designed to plane wood to a set thickness by means of a cutter block rotating about a horizontal axis with mechanical feed, the distance between the knives and the surface of the table supporting the workpiece being adjustable Note
22、 1 to entry: The upper surface of the workpiece is planed. Test procedure This clause of Part 1 is applicable, except as follows: 4.3 Operating conditions Addition: Transportable planers are tested under load observing the conditions shown in Table 101. During the test, planers supplied with a worki
23、ng stand are placed on this working stand. Other planers are placed on a test bench with a height of approximately 750 mm. BS EN 50632-3-3:2017 EN 50632-3-3:2017 (E) 5 Table 101 Operating conditions for transportable planers Material and set-up Planed beech, thickness (20 2) mm, length (800 2) mm, w
24、idth (50 2) mm. At the beginning of the test the wood shall have a humidity of maximum 12 %. Orientation and operation Planing one plane of the workpiece twice, followed by planing one narrow side of the workpiece once. Afterwards the other plane and narrow side of the workpiece are planed in the sa
25、me way. This results in six planing operations for each workpiece. Tool bit/settings Newly sharpened blades at the beginning of each of the three tests. At the manufacturers discretion the test may be performed without sharpening or changing the blade for the second and/or third test. Cutting depth:
26、 1 mm. Parallel guide: to be adjusted so that the workpiece is centered with respect to the cutter block. Feed force The feed force applied to the workpiece shall be sufficient to ensure stable operation with good performance. Test Number of workpieces to be planed as described above during the work
27、ing time of one test cycle: 4 for transportable planers with a planing width 260 mm; 6 for transportable planers with a planing width 260 mm. NOTE 1 The task per test cycle is easiest achieved in the following order: 1. Planing all workpieces first time on first plane; 2. Planing all workpieces seco
28、nd time on first plane; 3. Planing all workpieces on first narrow side; 4. Planing all workpieces first time on second plane; 5. Planing all workpieces second time on second plane; 6. Planing all workpieces on second narrow side. NOTE 2 24 planing operations in 10 min will require a planing speed of
29、 approximately 2,50 m/min, 36 planing operations in 10 min will require a planing speed of approximately 3,5 m/min, including sufficient time between the individual planing operations. If the above cannot be achieved within 10 min, the time is extended to allow the required number of planing operati
30、ons. Transportable thicknessers are tested under load observing the conditions shown in Table 102. During the test, thicknessers supplied with a working stand are placed on this working stand. Other thicknessers are placed on a test bench with a height of approximately 750 mm. BS EN 50632-3-3:2017EN

Orientation and operation Planing each pla
32、ne of the workpiece twice (four planing operations for each workpiece). Tool bit/settings Newly sharpened blades at the beginning of each of the three tests. At the manufacturers discretion the test may be performed without sharpening or changing the blade for the second and/or third test. Cutting d
33、epth: 1 mm. Feed rate As close as possible to 6 m/min. Test Number of workpieces to be planed as described above during the working time of one test cycle: 8 for transportable thicknessers with a planing width 260 mm; 10 for transportable thicknessers with a planing width 260 mm. NOTE The task per t
