IEC 61029-2-10:1998 pdf download.Safety of transportable motor-operated electric tools – Part 2-10: Particular requirements for cutting-off grinders
1 Scope
This clause of part 1 is applicable, except as follows:
1.1 Addition:
This standard applies to cutting-off grinders intended mainly for cutting metal with a plain
abrasive cutting-off wheel whose diameter does not exceed 406 mm and has a rated peripheral
speed not exceeding 80 m/s.
2 Definitions
This clause of part 1 is applicable, except as follows:
2.21 Replacement:
normal load
load obtained when the tool is operated continuously, with the torque applied to the spindle
such that the input, in watts, is equal to the rated input
NOTE – The normal load is based on the rated voltage or on the upper limit of the rated voltage range.
Addition:
2.101 cutting-off grinders
machine designed to cut metal by means of a plain abrasive cutting-off wheel which is fixed on
the tool spindle. The tool spindle is mounted on the outer end of an arm which is pivoted at its
inner end on the machine frame. The machine table has a clamping device to secure the
workpiece. The table can be traversed towards the cutting-off wheel (see figure 1 01 ).
2.102 tool spindle
spindle of the cutting-off grinder which supports and transmits the rotation of the plain abrasive
cutting-off wheel
2.103 guard
device which partially encloses the plain abrasive cutting-off wheel in order to protect the users
against accidental contact with the wheel in normal use and against the ejection of fragments
of the wheel in the protected area in the case of breakage of the wheel
2.104 flange assembly
means provided to clamp the plain abrasive cutting-off wheel to the machine spindle
2.105
straight recessed flange
flange with central recess suitable for a plain abrasive cutting-off wheel (see figure 1 06)
2.106
workpiece fixing device
device intended to support or hold the piece to be worked
3 General requirements
This clause of part 1 is applicable.
4 General notes on tests
This clause of part 1 is applicable.
5 Rating
This clause of part 1 is applicable.
6 Classification
This clause of part 1 is applicable.
7 Marking
This clause of part 1 is applicable, except as follows:
7.6 rated no-load speed in rev/min;
maximum diameter D of the wheel to be used;
indication of direction of rotation of the abrasive wheel.
Addition:
The direction of rotation of the wheel shall be indicated on the tool by an arrow raised or sunk,
or by other means not less visible and indelible.
7.13 Addition:
The handbook or information sheet shall include all the necessary information for safe working
with cutting-off grinders, such as method of operation, abrasive wheel change, maintenance,
assembly, transportation, etc.
9 Starting
This clause of part 1 is applicable.
10 Input and current
This clause of part 1 is applicable.
11 Heating
This clause of part 1 is applicable.
12 Leakage current
This clause of part 1 is applicable.
13 Radio and television interference suppression
This clause of part 1 is applicable.
14 Protection against ingress of foreign bodies and moisture resistance
This clause of part 1 is applicable.
15 Insulation resistance and electric strength
This clause of part 1 is applicable.
