CABLE GLANDS FOR ELECTRICAL INSTALLATIONS
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 62444 has been prepared by subcommittee 23A: Cable
management systems, of IEC technical committee 23: Electrical accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
23A/606/FDIS 23A/618/RVD

The committee has decided that the contents of this publication will remain unchanged until
the stability 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

5 General conditions for tests
5.1 Tests according to this standard are type tests.
5.2 Unless otherwise specified, the tests shall be carried out on new cable glands
assembled and mounted in accordance with the manufacturer’s or supplier’s instructions, as
declared in 7.3.
There shall be no adjustment between or during the tests.
NOTE Remounting of the sample between tests is not considered to be adjustment.
5.3 Unless otherwise specified, the tests shall be carried out at an ambient temperature of
(20 ± 5) °C.
5.4 Non-metallic and composite cable glands as well as the sealing systems of metallic
cable glands shall be pre-conditioned in an oven at (70 ± 2) °C and maintained for
(168 ± 4) h. If the maximum temperature declared by the manufacturer is greater than 65 °C,
then the test temperature shall be the declared temperature +5 °C.
5.5 Prior to the tests, non-metallic and composite cable glands as well as the sealing
systems of metallic cable glands shall be conditioned at a temperature of (20 ± 5) ºC and a
relative humidity between 40 % and 60 % for a minimum of 24 h or longer as specified by the
manufacturer.
5.6 Unless otherwise specified, three samples shall be subjected to the relevant tests.
In the case of a series of cable glands, three samples of the largest and smallest and one
sample of all other sizes of the same series shall be subjected to the relevant tests.
In the case of a cable gland utilising alternative sealing arrangements, each sealing
arrangement as specified by the manufacturer or supplier shall be considered as a sample.
If a sample does not satisfy a test due to an assembly or manufacturing fault, that test and
any preceding one which may have influenced the results of the test shall be repeated on 3
new samples of the size that failed. The tests which follow shall be made in the required
sequence. All new samples shall fulfil the requirements.
5.7 Unless otherwise specified test mandrels shall consist of bars having a hardness of
65 Shore D ± 15 points in accordance with ISO 868 and a surface roughness less than or
equal to 7 µm R in accordance with ISO 4287. The test mandrel shall have a tolerance of
a
± 0,2 mm for test mandrels up to and including 16 mm in diameter and ± 0,3 mm for test
mandrels larger than 16 mm in diameter. The shape shall be circular or a profile simulating
the outer dimension of the cables as declared by the manufacturer or supplier.
5.8 Clearance holes for test purposes shall have the values as given in Table 1, unless
otherwise specified by the manufacturer or supplier.
NOTE Annex B shows test sequences which shall be used for guidance only.

7 Marking and documentation
7.1 Marking
The cable gland shall be legibly and durably marked in a visible place with the following:
– name, logo or registered mark of the manufacturer or supplier;
– identification of the product.
Where it is not possible to apply the marking directly onto the product, then the marking shall
be placed on the smallest supplied package.
Compliance is checked by inspection.
Marking on the product not made by pressing, moulding or engraving is tested in accordance
with 7.2.
7.2 Durability and legibility
The test is made by rubbing the marking by hand for 15 s with a piece of cotton cloth soaked
with water and again for 15 s with a piece of cotton cloth soaked in petroleum spirit.
NOTE Petroleum spirit is defined as the aliphatic solvent hexane with a content of aromatics of maximum 0,1 %
volume, a kauri-butanol value of 29, initial boiling point of 65 °C, a dry point of 69 °C and a specific gravity of
approximately 0,68 kg/l.
After this test, the marking shall be legible to normal or corrected vision without additional
magnification.
The marking shall remain legible after all the non-destructive tests of this standard. It shall not
be possible to remove labels easily and they shall not show curling.
Compliance is checked by inspection.
7.3 Documentation
The manufacturer or supplier shall provide in his literature all information necessary for the
proper use and safe installation, such as
– sealing range (maximum and minimum cable dimensions);
– installation torque, if any;
– entry thread length, if any;
– entry thread size and type;
– m
