3 Terms and definitions
Add the following definition:
3.Z101
wall chaser
tool driving a rotating spindle, with a guide plate or guide roller or similar means, on which one or
more diamond wheels are mounted and used for non-through cutting operations by peripheral
grinding
6 Environmental requirements
Replace the existing 6.1.2.4 and 6.1.2.5 by the following:
6.1.2.4 Modification:
Cut-off machines and wall chasers are held and used as specified in 6.1.2.5.
For cut-off machines and wall chasers, the concrete block, its support and the tool shall be so arranged
that the geometric centre of the tool is 1 m above the reflecting plane, see Figure Z102 (dimension “y”)
and Figure Z104.
For cut-off machines, the centre of the 200 mm projecting end of the concrete slab shall be located
under the top microphone.
For wall chasers the centre of the concrete block shall be located under the top microphone.
6.1.2.5 Modification:
Cut-off machines are tested under load observing the conditions shown in Table Z101. Wall chasers
are tested under load observing the conditions shown in Table Z102.

Table Z101 — Noise and vibrations test conditions for cut-off machines
Concrete slab with minimum dimensions of 400 mm x 600 mm and a thickness of
Material and set
(50 ± 5) mm according to EN 1339. The concrete slab shall be stored under dry
up
conditions for at least 28 days and have the following specifications in accordance
with the following clauses of EN 1339:
Class 3 (5.3.3.2), Class 4 (5.3.4.2), Class 70 (5.3.6.2).
The concrete slab is rigidly fixed on a supporting concrete block with the minimum
dimensions of 800 mm x 500 mm x 200 mm.
At the beginning of the test the end of the concrete slab shall project 200 mm from
the concrete block and shall be readjusted at least after each series of tests.
Unless the machine is intended for operation with water supply, the dust shall be
collected during operation using a vacuum system. This shall be in place and fitted
correctly. The hose for dust extraction shall be connected and have adequate length
to eliminate the influence of the noise and vibration from the vacuum system on the
tool measurements.
See Figures Z102 and Z103.
Orientation Cut the concrete slab across the 400 mm width. During cutting the entire surface of
the guide plate or all guide rollers shall be in contact with the concrete slab.
The cut shall not be less than 20 mm from the edge of the slab.
Tool bit/settings New wheel(s) as specified for cutting concrete at the beginning of the entire test, to
be used by all three operators.
Speed setting devices, if any, shall be adjusted to the setting specified for cutting-off
concrete.
The depth gauge, if any, shall be adjusted to a cutting depth equal to the thickness
of the slab(s) plus 40 mm.
If no depth gauge is provided, the cut shall be made with a cutting depth of the
slab(s) plus approximately 10 mm to 40 mm.
If the maximum cutting depth of the cut-off machine is less than the values above,
the test is conducted at maximum cutting depth.
Feed force The forces applied to the tool shall be sufficient to obtain rated input/current ± 10 %
during cutting, applying approximately equal forces to both handles.
If either the input/current above cannot be achieved or the test cycle is less than
15 s, the test shall be conducted on two slabs stacked together.
Excessive grip forces shall be avoided.
One cut across the 400 mm width of the concrete slab.
Test cycle
The noise is measured during 15 s when the tool is in the middle of the concrete
slab.
For vibration, the measurement starts when the wheel enters the conc
