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.

8.14.1.101 Fastener driving tool safety warnings (except for multi-blow tools)
a) Always assume that the tool contains fasteners. Careless handling of the tool may result
in unexpected firing of fasteners and personal injury.
b) Disconnect the tool from the power source when loading and unloading fasteners,
making adjustments or changing accessories. The tool may be accidentally activated if
it is connected to the power source, which may result in personal injury.
c) Be careful when handling fasteners, especially when loading and unloading. The
fasteners have sharp points which may result in personal injury.
d) Do not point the tool towards yourself or anyone nearby. Unexpected triggering will
discharge a fastener, which may result in personal injury.
e) Keep fingers away from the trigger when not operating the tool and when moving from
one operating position to another. Unexpected triggering will discharge a fastener, which
may result in personal injury.

IEC 62841-2-16:2024 © IEC 2024 – 11 –
f) Hold the tool by insulated gripping surfaces, when performing an operation where the
fastener may contact hidden wiring or its own cord. A fastener contacting a "live" wire
may make exposed metal parts of the tool "live" and could give the operator an electric
shock.
g) Hold the tool with a firm grasp during operation. Uncontrolled recoil of the tool may result
in unintended activation, which may result in personal injury.
h) Keep all body parts such as hands and legs, etc. away from the firing direction of the
tool. The fastener may penetrate the workpiece as well as any object behind it, which may
result in personal injury.
i) When using the tool, keep all body parts such as hands and legs, etc. away from the
area where the fastener is driven into the workpiece. The fastener could deflect and exit
the workpiece, which may result in personal injury.
j) Do not actuate the tool unless the tool is placed firmly against the workpiece. If the
tool is not in contact with the workpiece, the fastener may be deflected away from the
workpiece, which may result in personal injury.
k) When fastening electrical cables, make sure the cables are not energized. Hold the
tool only by insulated gripping surfaces. Use only fasteners designed for electrical
cable installations. Inspect that the fastener has not damaged the insulation of the
electrical cables. A fastener that damages the insulation of electric cables can lead to
electric shock and fire hazards.
NOTE 101 The warning in item k) above is omitted for tools that are not intended to fasten electrical cables.
l) Do not use this tool for fastening electrical cables. It is not designed for electric cable
installation and may damage the insulation of electric cables, thereby causing electric shock
or fire hazards.
NOTE 102 The warning in item l) above is omitted for tools intended to fasten electric cables in accordance
with 8.14.2 b) 106).
m) Disconnect the tool from the power source if a fastener jams in the tool. While removing
a jammed fastener, the tool may be accidentally activated if it is connected to the power
source, which may result in personal injury.
n) Use caution while removing a jammed fastener. The mechanism may be under
compression and the fastener may be forcefully discharged, which may result in personal
injury.
NOTE 103 The warning in item n) above is omitted for tools that do not utilize a stored potential energy to drive
the fasteners.
8.14.1.102 Multi-blow tool safety warnings
a) Hold the tool by insulated gripping surfaces, when performing an operation where the
fastener may contact hidden wiring or its own cord. A fastener contacting a "live" wire
may make exposed metal parts of the tool "live" and could give the operator an electric
shock.
b) Keep all body parts such as hands and legs, etc. away from the driving direction of
the fastener. The fastener may penetrate the workpiece as well as any object behind it,
which may result in personal injury.
c) When fastening electrical cables, make sure the cables are not energized. Hold the
tool only by insulated gripping surfaces. Use only fasteners designed for electrical
cable installations. Inspect that the fastener has not damaged the insulation of the
electrical cables. A fastener that damages the insulation of electric cables can lead to
electric shock and fire hazards.
NOTE 101 The warning in item c) above is omitted for tools that are not intended to fasten electrical cables.
d) Do not use this tool for fastening electrical cables. It is not designed for electric cable

The temperatures are measured at the most unfavourable of the two voltage settings. The
temperatures that are measured by means of thermocouples are taken while the tool is
operating.
12.2.1 Replacement:
The test is conducted with or without fasteners in the tool.
NOTE 101 See 5.101 for tests that are conducted without fasteners.
For tools other than multi-blow tools, the tool is operated for 10 cycles or until thermal
equilibrium is reached, whichever is achieved first. Each cycle consists of the tool operating at
– a rate of one actuation approximately every 1 s; or
– for tools with an inherent operating cycle greater than 1 s, operation with consecutive
operating cycles
for 1 min and a rest period of 3 min with the tool switched off. The temperature rises are
measured at the end of the "on" period. At the manufacturer's option, the tool may be operated
without a rest period until thermal equilibrium is reached.
For multi-blow tools, the tool is operated continuously at a minimum load to activate the
percussion mechanism for 10 min or until thermal equilibrium is reached, whichever is achieved
first.
13 Resistance to heat and fire
IEC 62841-1:2014, Clause 13 is applicable.
14 Moisture resistance
IEC 62841-1:2014, Clause 14 is applicable.
15 Resistance to rusting

17.2 Replacement:
The test is conducted with or without fasteners in the tool.
NOTE See 5.101 for tests that are conducted without fasteners.
For tools other than multi-blow tools, the tool is operated at the cycle rate as specified in
12.2.1 for 20 000 actuations at a voltage equal to the highest rated voltage or equal to the
upper limit of the rated voltage range. It is not necessary for the test to be continuous.

– 14 – IEC 62841-2-16:2024 © IEC 2024
For multi-blow tools, the tool is cycled for 12 h at a voltage equal to the highest rated voltage
or equal to the upper limit of the rated voltage range. It is not necessary for the 12 h of
operation to be continuous. Each cycle of operation comprises an "on" period of 20 s and an
"off" period of 20 s, the "off" periods being included in the specified 12 h operating time. If the
cycle of operation limited by the construction is less than 20 s "on" and 20 s "off", then this
cycle may be used.
The tool may be switched on and off by means of a switch other than that incorporated in the
tool unless this disables a functionality of the tool switch.
During this test, replacement of the carbon brushes is allowed, and the tool is oiled and greased
as in normal use. If mechanical failure occurs and does not impair compliance with this
document, the part that failed may be replaced.
If the temperature rise of any part of the tool exceeds the temperature rise determined during
the test of 12.1, forced cooling or rest periods may be applied, the rest periods being excluded
from the specified operating time. If forced cooling is applied, it shall not alter the air flow of the
tool or redistribute carbon deposits.
During these tests, overload protection devices incorporated in the tool shall not activate.
18 Abnormal operation
IEC 62841-1:2014, Clause 18 is applicable, except as follows:
18.3 This subclause of IEC 62841-1:2014 is not applicable.
18.4 This subclause of IEC 62841-1:2014 is not applicable.
18.5.1 Replacement:
All fuses, thermal cut-outs, overload protectors and the like specified in 18.2 that are
accessible or that can be reset by the user without the aid of a tool and any self-resetting
protective devices are shorted.
The function of electronic circuits that prevent the tool from operating while the tool is stalled
shall be disabled unless that function has been evaluated as a safety critical function in
accordance with 18.8. The tool is connected to a minimum 12 kVA circuit.
The leakage current between live parts and accessible parts that are not grounded by class I
construction, is measured in accordance with Clause C.3 and is monitored throughout the test
and after the test until the leakage current has stabilized or decreases. The leakage current
shall not exceed 2 mA.
The armature or rotor of the motor is stalled or, for solenoid designs, the solenoid is
continuously operated for 15 min or until the tool open-circuits or flame appears. If either
condition occurs, immediately switch off the current and if flame appears, extinguish with CO
extinguisher.
After the tool has returned to within 5 K of the ambient temperature, an electric strength test
per Clause D.2 is performed between live parts and those accessible parts that are not
grounded by class I construction as follows:
– if a tool does not operate after the 15 min, apply a 1 500 V electric strength test;
– if a tool still operates after the 15 min, apply a 2 500 V electric strength test.

IEC 62841-2-16:2024 © IEC 2024 – 15 –
If the tool has permanently open-circuited due to an overtemperature condition before 15 min
has elapsed for any reason except the opening of a motor winding, the test shall be repeated.
This second test shall be terminated in the same manner unless the test is otherwise
satisfactorily completed.
If the test terminated due to a non-self-resetting thermal limit function of an electronic circuit,
this circuit shall either be bypassed or evaluated as a safety critical function in accordance
with 18.8.
If the tool has permanently open-circuited for reasons other than above, the cause is determined
and bypassed in a new sample and the test is repeated.
