Part 2-15: Particular requirements for hedge trimmers



FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60745-2-15 has been prepared by subcommittee 61F: Safety of
hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household

7 Classification
This clause of Part 1 is applicable.
8 Marking and instructions
This clause of Part 1 is applicable, except as follows:
8.1 Addition:
Hedge trimmers shall be marked with safety recommendations and warnings of the following
substance, which shall be written in one of the official languages of the country in which the
tool is to be sold. Alternatively, they shall be marked with symbols of the type specified in
Annex AA.
For hedge trimmers with a degree of protection of less than IPX4:
– “Do not expose to rain.”
For mains supplied tools:
– “Remove plug from the mains immediately if the cable is damaged or cut.”
If other symbols are used they shall be in accordance with ISO 3864-3.
8.12.1.1 Addition:
Hedge trimmer safety warnings:
• Keep all parts of the body away from the cutter blade. Do not remove cut material or
hold material to be cut when blades are moving. Make sure the switch is off when
clearing jammed material. A moment of inattention while operating the hedge trimmer may
result in serious personal injury.
• Carry the hedge trimmer by the handle with the cutter blade stopped. When
transporting or storing the hedge trimmer always fit the cutting device cover. Proper
handling of the hedge trimmer will reduce possible personal injury from the cutter blades.
• Hold the power tool by insulated gripping surfaces only, because the cutter blade
may contact hidden wiring or its own cord. Cutter blades contacting a "live" wire may
make exposed metal parts of the power tool "live" and could give the operator an electric
shock.
• Keep cable away from cutting area. During operation the cable may be hidden in shrubs
and can be accidentally cut by the blade.
8.12.2.b) Addition:
101) Advice to check the hedge for foreign objects, e.g. wire fences
102) Recommendation for the use of a residual current device with a tripping current of
30 mA or less
103) Instruction to hold the hedge trimmer properly, e.g. with both hands if two handles
are provided

19 Mechanical hazards
This clause of Part 1 is applicable, except as follows:
19.1 Addition:
The requirements of this subclause do not apply to those moving parts and guards which are
separately covered by 19.102 and 19.103.
19.101 Handles
The number of handles shall be in accordance with Table 101.
The handles shall be designed in such a way that each one can be grasped with one hand. The
gripping surface shall be at least 100 mm long. On bail or closed handles (U-shaped handles)
this dimension is related to the inner width of the gripping surface. On straight handles it is the
complete length between the housing and the end of the handle. There shall be a minimum
radial clearance of 25 mm around the gripping length.
If a part containing the motor complies with the dimensions above it may be considered as a
handle.
The gripping length of a bail or closed handle comprises any length that is straight or curved at
a radius of greater than 100 mm together with any blend radius but not more than 10 mm at
either or both ends of the gripping surface.
If a straight handle is supported centrally (i.e. T type) the gripping length shall be calculated as
follows:
– for handles with a periphery (not including the support) of less than 80 mm the gripping
length is the sum of the two parts on either side of the support;
– for handles with a periphery (not including the support) of 80 mm or more the gripping
length is the complete length from end to end.
If applicable, the part of the handle containing the blade control actuator shall be counted as
part of the handle gripping length. Finger grip or similar superimposed profiles shall not affect
the method of calculating handle gripping length.
Handles shall be positively locked in position. If they are adjustable in different positions it shall
not be possible to lock them in a position which contravenes other provisions of this standard.
For handles which are adjustable without the use of a tool, it shall not be possible to alter the
handle position when the cutting device is operating. When altering the handle position the
cutting device shall be inoperable.
Compliance is checked by inspection and measurements.
19.102 Hand protection
From any handle it shall not be possible to touch the moving cutter blade with the fingers
spread out.

---------------------- Page: 13 ----------------------
– 12 – 60745-2-15 © IEC:2006+A1:2009
Compliance is checked by the following test.
The requirements are met if all the handles are located so that the test distance from the cutter
blade of any handle is not less than 120 mm as shown in Figure 105.
If there is a guard, then the x and x distances shall be measured along the shortest path from
1 2
the backside of the handle, via the edge of the blade guard, to the nearest cutting edge of the
cutter blade.
19.103 Cutting device
To safeguard against contact with the cutter blade, hedge trimmers shall be constructed to
meet the requirements of one of the categories given in Table 101.
Table 101 – Hedge trimmer categories
Items with requirements Category number and requirements

For category 3, the 19 mm test probe in Figure 107 shall not contact any blade tooth.
Blunt extensions shall extend over the full length of the cutting device for the blade
configurations according to Figures 106 and 107. For cutting devices with blade configurations
as shown in Figure 108, the blunt extensions shall reach a distance of at least 400 mm from
any point of the rear face of the front handle (see Figure 109). If the front handle is located part
way along the cutting device the blunt extensions shall start at the first blade tooth and
continue until the 400 mm minimum distance beyond the rear of the front handle is reached.
