IEC 62841-3-9-2020 pdf free.Electric motor-operated hand-held tools, transporta ble tools and lawn and garden machinery – Safety – Part 3-9: Particular requirements for transportable mitre saws.
This part of IEC 62841 applies to transportable mitre saws intended to be used with a toothed saw blade for cutting wood and analogous materials, plastics and nonferrous metals except magnesium with a saw blade diameter not exceeding 410 mm, which hereinafter might simply be referred to as saw or tool.
This International Standard does not apply to mitre saws intended to cut other metals, such as magnesium, steel and iron. This document does not apply to mitre saws with an automatic feeding device.
NOTE 101 Transportable saws intended to cut ferrous metals will be covered by a future part of lEG 62841-3.
This document does not apply to saws designed for use with abrasive wheels.
NOTE 102 Transportable tools designed for use with abrasive wheels are covered by IEC 62841-3-10.
This document does not apply to tools combining the function of a mitre saw with the function of a table saw.
NOTE 103 Transportable tools combining the function of a mitr, saw with the funchon of a table saw are covered by a future part of IEC 6284 1-3.
2 Normative references
This clause of Part 1 is applicable, except as follows:
Addition:
ISO 180. Plastics — Determination of Izod impact strength
3 Terms and definitions
This clause of Part 1 is applicable, except as follows:
3.101 bevel angle angular displacement of the saw blade plane with respect to the table top plane. the position of the saw blade plane that is perpendicular to the table top being the 0 bevel position
3.102 compound angle angular displacement of the saw blade plane having a bevel and mitre angle other than 0
4 General requirements
This clause of Part I is applicable, except as follows:
4.101 Throughout the remaining part of this document, unless otherwise explicitly stated, whenever a requirement or a reference is made to
— “saw blade”:
this shall equally apply to any “saw blade” as specified in accordance with 8.14.2 a);
— “force” as a multiple of D:
the force shall be expressed in newtons (N) and the saw blade diameter D shall be expressed in millimetres (mm).
5 General conditions for the tests
This clause of Part 1 is applicable, except as follows:
5.17 Addition:
The mass of the tool shall include the fences and required workpiece clamp(s) in accordance with 21. 103 and 21.104. Further parts such as carrying means that are required in accordance with the instructions for the safe use of the tool shall be included in the mass.
5.101 Procedure to determine the horizontal cutting capacity
The mitre saw is fitted with a (2 ± 0,2) mm thick steel disc of diameter D in place of the saw blade and is set to 00 bevel angle. The saw unit is at its fully down position and, for a mitre saw with a sliding function, the saw unit is at its maximum extended horizontal position from the fence. The mitre saw is set for the mitre angle for which the horizontal cutting capacity measurement is desired.IEC 62841-3-9 pdf free download.
