IEC 62841-3-9-2020 pdf download.Electric motor-operated hand-held tools, transportable tools and lawn and garden machinery – Safety – Part 3-9: Particular requirements for transportable mitre saws.
This clause of Part 1 is applicable, except as follows: Addition:
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 41 0 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 1 01 Transportable saws intended to cut ferrous metals will be covered by a future part of IEC 62841 -3.
This document does not apply to saws designed for use with abrasive wheels.
NOTE 1 02 Transportable tools designed for use with abrasive wheels are covered by IEC 62841 -3-1 0.
This document does not apply to tools combining the function of a mitre saw with the function of a table saw.
NOTE 1 03 Transportable tools combining the function of a mitre saw with the function of a table saw are covered by a future part of IEC 62841 -3.

3 Terms and definitions
This clause of Part 1 is applicable, except as follows:
3.1 01 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
3.1 02 compound angle
angular displacement of the saw blade plane having a bevel and mitre angle other than 0°
3.1 03 cutting edge zone
outer 20 % of the radius of the saw blade
3.1 04 D specified diameter of the saw blade
3.1 05 fence
device to position the workpiece and absorb the horizontal forces from the saw blade during the cutting process
3.1 05.1 centre workpiece support
device that has a face supporting the workpiece in conjunction with the fence Note 1 to entry: See Figure 1 01 .
3.1 06 fully down position
position of the saw unit after adjustment of the saw in accordance with 8.1 4.2 a) 1 07) and any depth-of-cut stop as in 8.1 4.2 a) 1 08) disengaged or adjusted in order to produce the lowest position of the saw unit
3.1 07 horizontal cutting capacity
largest dimension perpendicular from the plane of the fence (width) of a workpiece with rectangular cross section that can be completely cut through with a single pass of the saw blade
Note 1 to entry: Subclause 5.1 01 provides a measurement procedure for horizontal cutting capacity.
3.1 08 kerf width
distance between two parallel planes that are touching the opposing sides of at least three saw blade tooth tips
3.1 09 kerf plate
portion of the table top on both sides of the saw blade intersect line with the table top for the purpose of minimizing the tearing of the wood fibres by the saw blade
Note 1 to entry: Depending on the design, the kerf plate is adjustable, replaceable or an integral part of the table top.
3.1 10 mitre angle
angular displacement of the plane of the fence with respect to the cutting line, the position of the saw blade plane that is perpendicular to the plane of the fence being the 0° mitre position
3.1 1 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.IEC 62841-3-9 pdf download.
