Foreword
The text of document 116/57/FDIS, future edition 1 of IEC 60745-2-22, prepared by IEC TC 116, Safety of
hand-held motor-operated electric tools, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, prepared by the Technical Committee CENELEC TC 116, Safety of motor-operated
electric tools, was submitted to the formal vote.
The combined texts were approved by CENELEC as EN 60745-2-22 on 2011-04-18.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2012-04-18
– latest date by which the national standards conflicting
(dow) 2014-04-18
with the EN have to be withdrawn
This European Standard is divided into two parts
Part 1: General requirements which are common to most hand-held electric motor operated tools (for the
purpose of this standard referred to simply as tools) which could come within the scope of this
standard;
Part 2: Requirements for particular types of tools which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
This draft European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of EC Directive
2006/42/EC. See Annex ZZ.
Compliance with the clauses of Part 1 together with this Part 2-22 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
Warning: Other requirements and other EC Directives can be applicable to the products falling within
the scope of this standard.
This European Standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.
This Part 2-22 is to be used in conjunction with EN 60745-1:2009. When this standard states "addition",
"modification" or "replacement", the relevant text in Part 1 is to be adapted accordingly.
Subclauses and figures which are additional to those in Part 1 are numbered starting from 101; additional
annexes are lettered AA, BB, etc.
Subclauses, tables and figures which are additional to those in IEC 60745-2-22 are prefixed “Z”.
Annexes ZA and ZZ have been added by CENELEC.
NOTE In this standard, the following print types are used:
- Requirements: in roman type;
- Test specification: in italic type;
- Notes: in smaller roman type.

This clause of Part 1 is applicable except as follows:
6.1.2.4 Modification:
Cut-off machines are held and used as specified in 6.1.2.5 and described in Table Z101. The concrete
block, its support and the tool shall be so oriented that the geometric centre of the tool is 1 m above the
reflecting plane (dimension “y” in Figure Z102). 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.

Table Z101 — Operating conditions for cut-off machines
Material and set up Concrete slab with minimum dimensions of 400 mm x 600 mm and a thickness of
(50 ± 5) mm according to EN 1339. The concrete slab shall be stored under dry
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 e.g. by means of clamps.
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 Cutting the concrete slab across the 400 mm width with the entire surface of the
guide plate or all guide rollers being 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. If the tool is intended to be used with
more than one wheel, then maximum number of wheels shall be fitted and set to the
maximum width of cut.
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 5 s,
the test shall be conducted on two slabs stacked together.
Excessive grip forces shall be avoided.
Test cycle One cut across the 400 mm width of the concrete slab.
Measurement starts when the wheel enters the concrete slab and finishes when the
wheel leaves the slab.

6.2 Vibration
6.2.4.2 Location of the measurement
Addition:
Figure Z101 shows the positions on the handles of different types of cut-off machines.
6.2.6.3 Operating conditions
Modification:
Cut-off machines intended to cut materials such as concrete, brick and masonry are tested under load
observing the conditions shown in Table Z101. The top of the slab shall have a distance to the ground of
maximum 450 mm (dimension “x” in Figure Z102).
6.2.7.2 Declaration of the vibration emission value
Addition:
The vibration emission value a of the handle with the highest emission and the uncertainty K shall be
h
declared.

Z101) Instruction on the correct use of the dust collection system unless the machine is intended for
operation with a liquid system

Cut-off machines not intended to be operated with a liquid system are considered to be tools where a
considerable amount of dust is produced.
