Part 3-14: Particular requirements for transportable drain cleaners

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.
International Standard IEC 62841-3-14 has been prepared by IEC technical committee 116:
Safety of motor-operated electric tools.
The text of this International Standard is based on the following documents:
FDIS Report on voting
116/340/FDIS 116/349/RVD
Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

This Part 3-14 is to be used in conjunction with the first edition of IEC 62841-1 (2014).
This Part 3-14 supplements or modifies the corresponding clauses in IEC 62841-1, so as to
convert it into the IEC standard: Particular requirements for transportable drain cleaners.
Where a particular subclause of Part 1 is not mentioned in this Part 3-14, that subclause
applies as far as relevant. Where this standard states “addition”, “modification” or
“replacement”, the relevant text in Part 1 is to be adapted accordingly.
The following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type;
– terms defined in Clause 3: bold typeface.
Subclauses, notes and figures which are additional to those in Part 1 are numbered starting
from 101.
A list of all parts of the IEC 62841 series, under the general title: Electric motor-operated
hand-held tools, transportable tools and lawn and garden machinery – Safety, can be found
on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.
NOTE The attention of National Committees is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC publication in
which to make products in accordance with the new requirements and to equip themselves for conducting new or
revised tests.
It is the recommendation of the committee that the content of this publication be adopted for implementation
nationally not earlier than 36 months from the date of publication.

– 8 – IEC 62841-3-14:2017 © IEC 2017
8.14.1.1 Addition:
Item 2) b) is not applicable.
8.14.1.101 Safety instructions for drain cleaners
NOTE 1 In the below instructions, on discretion of the manufacturer the term “drain” is replaced with the term
“pipe”.
a) Before using the tool, test the residual current device (RCD) provided with the
supply cord to insure it is operating correctly. A properly operating RCD reduces the
risk of electrical shock.
NOTE 2 It is possible to replace the term “residual current device (RCD)” with the term “ground fault circuit
interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
b) Only use extension cords that are protected by an RCD. The RCD on the machine
power cord will not prevent electrical shock from the extension cords.
NOTE 3 It is possible to replace the term “residual current device (RCD)” with the term “ground fault circuit
interrupter (GFCI)” or “earth leakage circuit breaker (ELCB)”.
c) Only grasp the rotating cable with gloves recommended by the manufacturer. Latex
or loose fitting gloves or rags can become wrapped around the cable and may result in
serious personal injury.
d) Do not allow the cutter to stop turning while the cable is turning. This can overstress
the cable and may cause twisting, kinking or breaking of the cable and may result in
serious personal injury.
e) One person must control both the cable and the switch. If the cutter stops rotating, the
operator must be able to turn the tool off to prevent the cable from twisting, kinking and
breaking.
f) Use latex or rubber gloves inside the gloves recommended by the manufacturer,
goggles, face shields, protective clothing, and respirator when chemicals, bacteria
or other toxic or infectious substances are suspected to be in a drain line. Drains
may contain chemicals, bacteria and other substances that may cause burns, be toxic or
infectious or may result in other serious personal injury.
g) Practice good hygiene. Do not eat or smoke while handling or operating the tool.
After handling or operating drain cleaning equipment, use hot, soapy water to wash
hands and other body parts exposed to drain contents. This will help reduce the risk
of health hazards due to exposure to toxic or infectious material.
h) Only use the drain cleaner for the recommended drain sizes. Using the wrong size
drain cleaner can lead to twisting, kinking or breaking of the cable and may result in
personal injury.
i) Always use the rear guide hose while operating the tool and ensure the cable does
not extend beyond the rear guide hose. This prevents the cable from whipping which
may result in entanglement and personal injury.
NOTE 4 The above warning only applies for sectional machines.
8.14.2 a) Additional items:
101) Information on the permitted length(s) and diameter(s) of the drain cleaner cable or
drain cleaner cable sections;
102) Instruction on how to install the drain cleaner cable;
103) For sectional machines: instruction on how to install the rear guide hose;
104) Information on recommended drain cleaner cable diameters for different pipe
diameters.
8.14.2 b) Additional items:
101) Information on the correct gloves to wear during operation;

102) Information on the distance the drain cleaner is to be placed from the drain or pipe
opening.
103) Instruction on drain cleaner cable feed and rotation.
8.14.2 c) Additional items:
101) Instruction on how to inspect and maintain the drain cleaner cable.
9 Protection against access to live parts
This clause of Part 1 is applicable.
10 Starting
This clause of Part 1 is applicable.
11 Input and current

This clause of Part 1 is applicable.
14 Moisture resistance
This clause of Part 1 is applicable, except as follows:
14.5 Replacement:
A residual current device used to provide protection from shock in the case of moisture shall
comply with IEC 61540:1999 and shall meet the following requirements a) to c):
1) The RCD shall disconnect both mains conductors, but not the earth conductor if provided,
when the leakage exceeds 10 mA and with a maximum response of 300 ms.
Compliance is checked by inspection and the test of 9.9.2 of IEC 61540:1999. In addition,
during the test, the earthing conductor shall not become disconnected.
2) The RCD shall be reliable for its intended use.
Compliance is checked at rated voltage by operating the residual current device under
conditions of simulated leakage as in a) above during conditions of locked rotor of the tool
for 50 cycles. The residual current device shall operate correctly for all cycles.
3) The RCD shall be installed such that it is unlikely to be removed during use or normal
maintenance.
This requirement is considered fulfilled if the residual current device is fixed to the tool
or the supply cord connected to the tool.
Where fitted in the supply cord, the residual current device shall be provided with
type Y attachment or type Z attachment for connection with the supply cord and
interconnection cord.

Annex K
(normative)
Battery tools and battery packs
K.1 Addition:
All clauses of this Part 3-14 apply unless otherwise specified in this annex.
K.8.14.1.101 Items a) and b) are not applicable.
K.14.5 This subclause is not applicable.
K.21.15 This subclause is not applicable.
NOTE 101 In Europe (EN 62841-3-14), the following additional subclause applies:
K.21.18.Z101 Isolation and disabling device
Tools with an integral battery 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 all poles 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 1 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.
NOTE 2 The risk of accidental reconnection for a power switch is addressed by the requirement of
21.18.1.2. The other examples in NOTE 1 achieve this by the necessary actions for reconnection.
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.

Annex L
(normative)
Battery tools and battery packs provided with mains
connection or non-isolated sources
L.1 Addition:
