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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at

Part 3-15: Particular requirements for transportable magnetic drills
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.

Addition:
Magnetic drill stands shall be marked with the following safety warnings:
– " WARNING – Do not use this tool if you or any bystanders have a cardiac pacemaker or
other medical implants" or symbol P007 of ISO 7010; and
– “ WARNING – Always use the safety strap when operating the tool” or a symbol that is
described in the instruction manual.
8.14.1 Addition:
The additional safety instructions as specified in 8.14.1.101 shall be given. This part may be
printed separately from the "General Power Tool Safety Warnings".
8.14.1.101 Safety instructions for magnetic drills
a) Do not use this tool if you or any bystanders have a cardiac pacemaker or other
medical implants. Cardiac pacemakers and other medical implants may malfunction due
to magnetic fields emitted by the tool, which may result in personal injury.
b) Always check the safety strap for wear or damage before each use. A worn or damaged
safety strap may fail unexpectedly during use and may result in personal injury.
NOTE 101 It is possible to replace the term "strap" with "chain" or another descriptive term in the warning in
item b) above.
c) Only attach the magnetic drill to ferrous metal. The magnetic base will not secure
properly to non-ferrous metals, such as non-magnetic grades of stainless steel.
d) Clean the surface before attaching the drill stand to the work surface. Paint, rust or
scale decrease the holding strength of the magnet. Chips, burrs, dirt and other foreign
matter on the surface of the magnetic base will also decrease holding power.
e) Always secure the magnetic base on a smooth, flat work surface. If the workpiece is
uneven and not smooth or flat, the magnetic base may release from the workpiece, causing
unexpected movement of the tool or workpiece and personal injury.
f) Use clamps or other practical ways to secure and support the workpiece to a stable
platform. It is important to support the workpiece properly to minimise body exposure,
binding, or loss of control.
– 10 – IEC 62841-3-15:2024 © IEC 2024
g) Always use the safety strap provided or recommended to secure the tool to the
workpiece before turning on the drill motor. The magnetic base may release from the
workpiece, causing unexpected movement of the tool or workpiece and personal injury.
NOTE 102 It is possible to replace the term "strap" with "chain" or another descriptive term in the warning in
item g) above.
h) Always activate the magnetic base and make sure it is securely attached to the
workpiece before turning on the drill motor. Failure to secure the magnetic base to the
workpiece may cause unexpected movement of the tool or workpiece and personal injury.
i) Always ensure the workpiece is in a fixed or stable position. Unexpected movement of
the workpiece may result in personal injury.
j) Make sure you are in a stable position and able to control the tool while releasing the
tool from the workpiece. A loss of control upon releasing the tool from the workpiece may
result in personal injury.
k) Keep your hands out of the drilling area while the tool is running. Contact with rotating
parts or chips may result in personal injury.
l) Make sure the bit is rotating before feeding into the workpiece. Otherwise the accessory
may become jammed in the workpiece causing unexpected movement of the workpiece and
personal injury.
m) Do not use excessive feed force while drilling. Use of excessive feed force may cause
the magnetic base to release from the workpiece, causing unexpected movement of the tool
or workpiece and personal injury.
n) Avoid generating long chips by regularly interrupting downward pressure. Sharp metal
chips may cause entanglement and personal injuries.
o) Never remove chips from the drilling area while the tool is running. To remove chips,
move the bit away from the workpiece, switch off the drill motor and wait for the bit
to stop moving. Use tools such as a brush or hook to remove chips. Contact with
rotating parts or chips may result in personal injury.
p) When performing drilling that requires the use of cutting fluid, route the cutting fluid
away from the operator’s work area or use a liquid collection device. Such
precautionary measures keep the operator’s work area dry and reduce the risk of electric
shock.
q) When the bit is jammed, stop applying downward pressure and turn off the tool.
Investigate and take corrective actions to eliminate the cause of bit jamming.
r) When restarting a drill in the workpiece, check that the bit rotates freely before
starting. If the bit is bound it may not start, may overload the tool, or may cause the drill
stand release from the workpiece.
s) Do not deactivate the magnetic base until the tool is turned off and the bit has come
to a complete stop. Premature deactivation of the magnetic base may cause unexpected
movement of the tool or workpiece and personal injury.
