Test Report No.: 17702074 003
Part I of II
manufactured from one or a combination of the materials
required in a), b) or c) or from cast iron with an ultimate
tensile strength of at least 200 N mm
-2
and a wall
thickness of at least 5 mm.
Verification: By checking the relevant drawings, tensile
strength, measurement, performing the impact test given
in Annex H for plastic materials other than polycarbonate
and inspection of the machine.
NOTE For the ultimate tensile strength, a confirmation from the
manufacturer of the material can be useful.
Avoidance of contact between the saw blades and/or
machine parts
The machine shall be designed in such a way that in any
case it is not possible to mount a main saw blade or a
scoring saw blade with a larger diameter than the largest
one for which the machine is designed.
In circular saw bench when a scoring saw blade is
mounted it shall not be possible to mount a main saw
blade that would come in contact with such additional saw
blade taking account of all height adjustment positions of
the saw blades.
Verification: By checking the relevant drawings, inspection
of the machine and relevant functional testing of the
machine.
Tool holder and tool design
Saw spindles shall be manufactured in accordance with
the tolerances given in Annex C.
Verification: By checking the relevant drawings and by
measurement.
When it is necessary to hold the spindle stationary for saw
blade changing, a spindle holding/blocking device shall be
provided, e.g. a double spanner arrangement or an
integral locking bar inserted through the spindle. When a
blocking device is used, it shall prevent tool spindle
rotation and shall not be deformed after starting the
spindle drive motor, with the blocking device in place.
Verification: By checking the relevant drawings, inspection
of the machine, measurement and relevant functional
testing of the machine.
A bar is provided for
locking the spindle. No
deformation occurs when
stating the machine with
the bar in locking position.
