14、is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CENELEC and/or CEN shall not be held responsible for identifying any or all such patent rights. This European Standard is divided into three parts: Part 1: General requirements for the dust me
15、asurement which are common to electric motor-operated tools (for the purpose of this standard 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 particul
16、ar characteristics of these specific tools. This Part 3 is to be used in conjunction with 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 re
17、spirable dust emitted by transportable mitre saws. Where a particular subclause 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. Sub
18、clauses, tables and figures which are additional to those in Part 1 are numbered 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
19、 italic type; explanatory matter: in smaller roman type. The terms defined in Clause 3 are printed in bold typeface.

21、1 mitre saw saw consisting of a table top and a fence which support and position the workpiece, and a saw unit, projecting over the table top Note 1 to entry: Cutting is achieved by moving the saw unit through a plunging action or a combination of plunging and sliding actions. The workpiece does not
22、 move with respect to the table top or fence during cutting. Some mitre saws have a saw unit that is adjustable to cut at a bevel angle, a mitre angle or both angles to create a compound cut. 4 Test procedure This clause of Part 1 is applicable, except as follows: 4.3 Operating conditions Addition:
23、Transportable mitre saws are tested under load observing the conditions shown in Table 101. During the test, mitre saws supplied with a working stand are placed on this working stand. Other mitre saws are placed on a test bench with a height of approximately 750 mm. BS EN 50632-3-9:2016 EN 50632-3-9
24、:2016 (E) 5 Table 101 Operating conditions for transportable mitre saws Material and set-up Medium-density fibreboard (MDF): in accordance with EN 622-5, density (750 50) kg/m, thickness (19 1,0) mm, width = 2/3 of the maximum horizontal cutting capacity of the transportable mitre saw but not more t
25、han 200 mm, any length. Orientation and operation Sawing of approximately 10 mm wide strips over the width of the workpiece. Tool bit/settings New saw blade as specified by the manufacturer for sawing fibreboard at the beginning of each of the three tests. Speed setting devices, if any, shall be adj
26、usted to the setting specified for sawing chipboard. Mitre angle and bevel angle are both set to 0. Feed force The feed force applied to the tool shall be sufficient to ensure stable operation with good performance. Test During the working time of one test cycle, following number of cuts as specifie
27、d above are performed equally distributed over the working time: 50 cuts for transportable mitre saws without sliding function; 40 cuts for transportable mitre saws with sliding function. If the above cannot be achieved within 10 min, the time is extended to allow the required number of cuts. 5 Inst
28、rumentation This clause of Part 1 is applicable. 6 Information to be reported This clause of Part 1 is applicable, except as follows: p) Modification:Information about extension of the cycle time in case the required number of cuts could not be achieved within 10 min.
