Part 2-16: Particular requirements for tackers

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 60745-2-16 has been prepared by subcommittee 61F: Safety of
hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household
and similar electrical appliances.
The text of this standard is based on the following documents:
FDIS Report on voting
61F/703/FDIS 61F/711/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This second edition cancels and replaces the first edition published in 1993 and constitutes a
technical revision. Main changes include Clause 8: Markings and instructions, introducing

60745-2-16 © IEC:2008 – 3 –
detailed safety warnings; Clause 11: Input and current, introducing specification for rated
current and input; Clause 12: Heating, with a modified test cycle; Clause 17: Endurance, with
testing based on actuation numbers rather than on time; Clause 18: Abnormal operation,
introducing an overload test of Part 1 slightly modified for tackers; Clause 19: Mechanical
hazards, with requirements for actuating the tool dependant on the kind of actuation system.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
This part 2 is to be used in conjunction with the latest edition of IEC 60745-1. It was
established on the basis of the fourth edition (2006) of that standard.
NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60745-1.
This part 2 supplements or modifies the corresponding clauses in IEC 60745-1, so as to
convert that publication into the IEC standard: Particular requirements for tackers.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies
as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,
the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:
– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;
– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including
those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.
A list of all parts of the IEC 60745 series, under the general title: Hand-held motor-operated electric
tools – Safety, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,

– 6 – 60745-2-16 © IEC:2008
8.12.1 Addition:
The specific tool safety warnings for tackers are given in 8.12.1.101. The term tacker in these
warnings may be replaced by a specific tool designation, such as stapler, nailer, etc.
8.12.1.101 Safety instructions for tackers
Tacker safety warnings
– Always assume that the tool contains fasteners. Careless handling of the tacker can
result in unexpected firing of fasteners and personal injury.
– Do not point the tool towards yourself or anyone nearby. Unexpected triggering will
discharge the fastener causing an injury.
– 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 your
target.
– Disconnect the tool from the power source when the fastener jams in the tool. While
removing a jammed fastener, the tacker may be accidentally activated if it is plugged in.
– Use caution while removing a jammed fastener. The mechanism may be under
compression and the fastener may be forcefully discharged while attempting to free a
jammed condition.
NOTE This warning may be omitted for tackers that do not utilize a stored potential energy to drive the fasteners.
– When fastening electrical cables, make sure the cables are not energized. Hold the
tacker 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 This warning to be provided for tackers suitable for fixing electric cables.
– Do not use this tacker 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 This warning is to be provided for tackers not suitable for fixing electric cables.
8.12.2 b) Addition:
101) types and dimensions, or manufacturer’s reference numbers, of the recommended
fasteners;
102) information on the operation and the operating controls of the tool;
103) information on how to operate the tool safely in order to minimise the risk of personal
injury to the operator or other person who may be in the vicinity;
104) information whether or not the tacker is suitable for fixing electric cables;
105) if applicable, information on the fasteners to be used for fixing electric cables.
9 Protection against access to live parts
This clause of Part 1 is applicable.
10 Starting
This clause of Part 1 is applicable.

60745-2-16 © IEC:2008 – 7 –
11 Input and current
This clause of Part 1 is applicable, except as follows:
Replacement:
The rated current shall be within ± 20 % of the measured current. The rated input may be
calculated from the rated current.
For tools marked with one or more rated voltage ranges, the test is made at both the upper
and lower limits of the ranges, unless the marking or the rated power input is related to the
mean value of the relevant voltage range, in which case the test is made at a voltage equal to
the mean value of that range.
Compliance is checked by the following test.
The tool is operated without fasteners at a rate of one actuation every 1 s or as limited by tool
design. The measured current is the r.m.s. value over a period of 10 s.
12 Heating
This clause of Part 1 is applicable, except as follows:
12.2 Modification:
The tool is operated without fasteners for 10 cycles or until temperatures stabilise, whichever
is achieved first. Each cycle consists of the tool operating at a rate of one actuation every 1 s
or as limited by tool design 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 continuously until thermal stabilisation.
13 Leakage current
This clause of Part 1 is applicable.
14 Moisture resistance
This clause of Part 1 is applicable.
15 Electric strength
This clause of Part 1 is applicable.
16 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
17 Endurance
This clause of Part 1 is applicable, except as follows:

– 8 – 60745-2-16 © IEC:2008
17.2 Replacement:
The tool is operated without fasteners at the cycle rate as specified in 12.2 for 10 000
actuations at a voltage equal to 1,1 times rated voltage and then for another 10 000
actuations at a voltage equal to 0,9 times rated voltage.
The tool may be switched on and off by means of a switch other than that incorporated in the
tool.
During this test, if applicable, replacement of the carbon brushes is allowed, and the tool is
oiled and greased as in normal use.
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 are applied.
During these tests, overload protection devices shall not operate.
During the test, replacement of any mechanical components that fail without impairing safety
is allowed.
18 Abnormal operation
This clause of Part 1 is applicable, except as follows:
18.12 Replacement:
A class I tool employing class II construction (see 5.10) or a class II tool shall be able to
operate under extreme overload conditions without impairing protection against electric shock.
Compliance is checked by the following test on a separate sample.
All fuses, thermal cut-outs, and overload protectors and the like specified in 18.1 that are
accessible to the user without the aid of a tool shall be shorted.
The sample is connected to a minimum 12 kVA circuit. The armature/rotor of the tool is stalled
or, for solenoid designs, the solenoid is continuously energised, for 15 min or until the tool
open-circuits or flame appears. If either condition occurs, immediately de-energise the tool
and if flame appears, extinguish with CO extinguisher. The leakage current between live
parts and accessible parts, measured in accordance with Clause 13, is monitored throughout
the test and after the test until leakage current has stabilized or decreases. Leakage current
shall not exceed 2 mA.
After the tool is cooled to room temperature, an electric strength test per Clause 15 is
performed between live parts and accessible parts as follows:
– if a tool does not operate after 15 min, apply a 1 500 V electric strength test;
– if a tool operates after 15 min, apply a 2 500 V electric strength test.
19 Mechanical hazards
This clause of Part 1 is applicable, except as follows:

60745-2-16 © IEC:2008 – 9 –
19.101
The tool shall be provided with a user-operated trigger such that the tool cannot be actuated
when the trigger is in a released position (i.e. in an “off” position) and either:
a) have a workpiece contact so that it is not possible to operate the tool unless both the
trigger and the workpiece contact have been activated,
or
b) be so designed that the fasteners have a speed in free air at the point they leave the tool
no greater than 15 m/s, and have a mass no greater than 0,3 g.
In addition, it shall not be possible to eject fasteners consecutively without first either
operating the trigger or the workpiece contact.
Compliance is checked by inspection, measurement and by practical tests in all possible
positions of use of the tool.
19.102 The tool shall either:
– be manufactured with an actuation system meeting the requirements of single sequential,
full sequential, selective or automatic reversion actuation, or
– have a workpiece contact designed such that, in addition to the force due to its weight
distribution, the tool shall be pressed against the workpiece with a force of at least 50 % of
the tool weight, this force need not exceed 5 N, to activate the release of the fastener. The
mass of the tool is measured without supply cord and fasteners.
Compliance is checked by measurement and manual test, while the tacker is placed on a
horizontal surface in such orientation that the workpiece contact activation is in the vertical
direction.
19.103 For tools required to have workpiece contact, it shall not be possible to actuate the
tool when lifting it by the trigger from any resting position.
Compliance is checked by the following test.
The tool is loaded with the minimum number of fasteners and is placed on a level surface. A
force of 25 % of the tool mass is applied to the top of the tool. The force is then removed and
the tool is raised by the trigger using a 12 mm rod at the midpoint of the trigger. Means shall
be provided to ensure that the tool does not tip laterally by more than 10º during the test.
The tool shall not actuate during the test.
The force of 25 % of the tool mass is calculated using the tool mass without supply cord or
fasteners.
19.104 Tools manufactured with selective actuation shall be shipped with either single
sequential actuation, full sequential actuation, neutral or off selected.
Compliance is checked by inspection.
19.105 Workpiece contacts shall be designed to possess sufficient protection against
premature failure in normal use, if such failure would cause actuation of the tool by the
operation of the trigger alone.
Compliance is checked through failure analysis or by the following test.

– 10 – 60745-2-16 © IEC:2008
The workpiece contact is cycled 50 000 times under conditions of its maximum travel. At the
conclusion of this conditioning, the tool shall not actuate by the use of the trigger alone in any
orientation. Operation of the tool during the conditioning is not required unless not doing so
changes the force or travel on the workpiece contact.
