Part 2-17: Particular requirements for routers and 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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.

18 Abnormal operation
This clause of Part 1 is applicable.
19 Mechanical hazards
This clause of Part 1 is applicable, except as follows:
19.1 Replacement:
Routers shall be equipped with a base plate which surrounds the cutter in the plane of the
plate so as to prevent inadvertent contact with the cutter during normal operation.
Compliance is checked by inspection.
Additional subclauses:
19.4.101 At least two handles are required if the mass exceeds 2 kg.
The handles shall be so shaped or located as to minimise the risk of inadvertent contact of
the user’s hand with rotating parts. Inadvertent contact of the user’s hand is, for example,
considered to be sufficiently prevented if the gripping area of the handle is provided with a
suitable shroud(s) or barrier at its end(s) adjacent to the body of the tool, or the distance from
a defined measuring point on the handle surface to the cutter is a minimum of 120 mm.
Compliance is checked by inspection and measurement. The measurement shall be carried
out as a chain distance (see Figure 101).
With the base plate set to maximum depth of cut, to establish the measuring point on the
auxiliary handle, follow the outlined procedure below.
a) Establish the closest (A) and the most distant (B) points from the plane of the base plate
on the handle. Equidistant between points (A) and (B), draw the horizontal intersecting line
on the plane parallel with the base plate and the surface of the handle.
b) The point on the intersecting line of the handle surface with the largest radial distance
from the centreline of the spindle is the defined measuring point.
60745-2-17 © IEC:2010 – 9 –
The motor housing can be considered as a handle, if suitably shaped.
The mass is measured without accessories, e.g. mandrels, cutters and flexible cable or cord.
If the motor housing is considered as the only gripping area, it shall be so shaped as to
minimise the risk of inadvertent contact of the user with rotating parts. Inadvertent contact of
the hand of the user is considered to be sufficiently prevented, if there is a 6 mm high barrier
between the grasping surface and the cutter or if the mains switch area is at a distance of at
least 120 mm from the cutter, taking into account any base plate which may be fitted.
Adjustment elements capable of being readjusted while the tool is operating, e.g. “revolving
depth gauge”, shall be located so that touching of rotating parts is avoided.
Compliance is checked by inspection.
19.101 The no-load speed of the spindle at rated voltage or at the upper limit of the voltage
range shall not exceed 110 % of the rated no-load speed.
Compliance is checked by measuring the speed of the spindle after the tool has been
operating for 15 min at no-load.
