Part 2-6: Particular requirements for hand-held hammers

AMENDMENT 1
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.

19 Mechanical hazards
Replace the existing text of 19.102.3 with the following new text:
19.102.3 Assessment to determine tool configuration
This assessment is only applicable for tools that employ (an) electronic circuit(s) that affect(s)
the output torque in the test of 19.102.4.
Prior to each measurement, the sample is operated for at least 5 min at no-load. After each
5 min operation period, the measurement shall be started within 20 min.
All measurements are made with the tool sample running in the forward position.
The sample is connected to the measurement fixture and is fixed during the test.
For tools with a soft start function, the test of 19.102.4 through steps 1) and 2) is conducted on
the sample with the soft start function enabled and then repeated with the soft start function
disabled. If analysis shows that the tool will not operate with the soft start function disabled,
then the test with the soft start function disabled is not conducted. For tools employing
electronically commutated motors, the configuration that results in the greatest output torque
shall be used for the test of 19.102.4. For tools other than those employing electronically
commutated motors, the configuration that results in the greatest output torque shall be used
for the following test.
For tools other than those employing electronically commutated motors, when all functions
affecting the test value of the output torque, except for any soft start function, are not evaluated
as SCFs according to 18.8 (e.g. current limit and stall detection), the tool configuration for the
test of 19.102.4 shall be the configuration that results in the greatest output torque for one trial
of the test of 19.102.4 through steps 1) and 2) as specified below:
– all functions affecting the output torque enabled; or
– each function not evaluated as an SCF affecting the output torque disabled one at a time.
Replace the existing text of 19.102.4 with the following new text:
19.102.4 Test procedure
If applicable, the sample is configured as specified in 19.102.3.
Prior to the test, the sample is operated for at least 5 min at no-load. After the 5 min operation
period, the test shall be started within 20 min.
All measurements are made with the tool sample running in the forward position.
The sample is connected to the measurement fixture and is fixed during the test. The
measurement is conducted by using seven trial measurements of the same sample, each trial
conducted as follows:
1) Energize the tool to the full "on" position as quickly as possible and allow the joint to be
tightened until it comes to a complete stop.

2) Record the measured output torque.
a) For tools without a mechanical overload clutch, the output torque is determined by either
i) or ii):
i) For signals that are stable for a minimum of 2 ms after the initial peak (if present),
the output torque value is determined by measuring over the stable region for an
interval T not exceeding 100 ms. If there is variation during this interval, the average
value shall be used. See Figure 109.
ii) For signals that are not stable for a minimum of 2 ms after the initial peak, the output
torque value shall be the RMS value of the signal over the rotation from off until peak
torque is achieved. See Figure 110.
NOTE 101 Torque signals can exhibit a transient peak with a relatively stable signal following the peak.
The stable signal can exhibit relatively slow change due to, for example, heating of the windings. The stable
signal can also exhibit periodic signal variation due to torque ripple. Averaging over this stable period
provides a meaningful torque value. The transient peak and the stable region are not always present.
b) For tools with a mechanical overload clutch:
The output torque is determined by the peak value of the first peak that occurs after
starting the trial. Later peaks, even if they appear to have greater values, are not taken
into account. See Figure 111.
3) Before the next trial, disconnect the spindle from the test fixture and operate the tool under
no-load for a minimum of 3 s. Allow the tool to cool for a minimum of 2 min before the next
trial.
M is computed as the average of five of the measurements from each of the seven trials, with
R
the highest and lowest measurement eliminated. The standard deviation of the five
measurements shall also be computed and shall be less than 5 %. If it is not, then the fixture
shall be adjusted to achieve the required repeatability.
NOTE 102 It is recognized that disabling functions that affect the torque can result in a test where the tool is
permanently impaired after the test.

Replace the existing Table I.102 with the following new table:
Table I.102 – Noise test conditions for rotary hammers
Orientation Drilling vertically down into a concrete block having the formulation specified in Table I.103
and having the minimum dimensions 500 mm × 500 mm and 200 mm in height and
supported on resilient material. The concrete block, its support and the tool shall be so
oriented that
– the geometric centre of the tool is 1 m above the reflecting plane;
– the centre of the concrete block is located under the top microphone "5"; as shown in
Figure I.101; and
– the sides of the concrete block are parallel to the square formed by the microphones
"1" to "4" as shown in Figure I.101.
For consistency of results the drilled holes are blind holes. If the drill bit breaks through,
reducing the depth of the hole slightly is a method to avoid this.
New drill bit as recommended by the manufacturer for hammer drilling in concrete and of
Tool bit
the size defined in Table I.105.
For battery tools, the mass of the tool to select the drill bit is the mass without any
detachable battery pack or separable battery pack attached to the tool.
Feed force The feed force applied to the tool shall be sufficient to ensure stable operation with good
performance.
Test cycle Measurement starts when the drill bit has reached a depth equal to its diameter, and
stops when the depth of hole according to Table I.105 has been reached and before the
drill bit is removed from the hole.

Annex K – Battery tools and battery packs
Replace the existing text of K.19.102.3 with the following new text:
K.19.102.3 Assessment to determine tool configuration
This assessment is only applicable for tools that employ (an) electronic circuit(s) that affect(s)
the output torque in the test of K.19.102.4.
Prior to each measurement, the sample is operated for at least 5 min at no-load using any
suitable battery. After each 5 min operation period, the measurement shall be started within
20 min.
The sample is tested together with its intended battery. If more than one battery is specified
for use with the tool, the battery with the highest short-circuit current shall be used.
At the beginning of the test, the battery shall be fully charged.
All measurements are made with the tool sample running in the forward position.
The sample is connected to the measurement fixture and is fixed during the test.
For tools with a soft start function, the test of K.19.102.4 through steps 1) and 2) is conducted
on the sample with the soft start function enabled and then repeated with the soft start function
disabled. If analysis shows that the tool will not operate with the soft start function disabled,
then the test with the soft start function disabled is not conducted. For tools employing
electronically commutated motors, the configuration that results in the greatest output torque
shall be used for the test of K.19.102.4. For tools other than those employing electronically
commutated motors, the configuration that results in the greatest output torque shall be used
for the following test.

K.21 Construction
Replace the existing NOTE 101 with the following new NOTE:
NOTE 301 In Europe (EN IEC 62841-2-6), the following additional subclause applies:
K.21.18.Z101 Isolation and disabling device
Rotary hammers with an integral battery, except for tools with M ≤ 25 Nm measured in accordance with
R
19.102 and having only a single handle, shall either be equipped
– with an isolation device to prevent the risk of injury from mechanical hazards during servicing or user
maintenance; or
– with a disabling device that prevents unintentional starting of the tool.
An isolation device shall
– provide disconnection of at least one pole of the battery from the serviceable region of the tool;
– be equipped with an unambiguous indication of the state of the disconnection device which corresponds to
each position of its manual control (actuator);
– be provided with protection against accidental reconnection.
NOTE Examples of methods to achieve this disconnection include removable jumpers, integral batteries that
can be disconnected for servicing or user maintenance, or an electromechanical power switch with a direct
mechanical link between the actuator and the contact.
A disabling device may be achieved by any of the following:
– a self-restoring or non-self-restoring lock-off device where two separate and dissimilar actions are necessary
before the motor is switched on (e.g. a power switch which has to be pushed in before it can be moved
laterally to close the contacts to start the motor). It shall not be possible to achieve these two actions with
a single grasping motion or a straight-line motion;
– a removable disabling device provided with the tool where it shall not be possible for the tool to be operated
when either applied or removed.
Compliance is checked by inspection and by manual test.
