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 61439-7 has been prepared by subcommittee 121B: Low-voltage
switchgear and controlgear assemblies, of IEC technical committee 121: Switchgear and
controlgear and their assemblies for low voltage.
This first edition cancels and replaces the relevant technical specification published in 2014. It
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
technical specification:
a) a new classification of the stationary ASSEMBLIES in accordance with their mechanical
resistance (5.702);
b) a new Table 702 with the list of tests and relevant severities to which the ASSEMBLIES have
to be subjected according to the classification mentioned at point a);

– 4 – IEC 61439-7:2018 © IEC 2018
c) a new Annex (CC) with a new endurance test for the individual switching devices intended
to be used in AEVSC, if they have not already been tested against this requirement;
d) a general editorial review and a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
121B/74/FDIS 121B/77/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 standard is to be read in conjunction with IEC 61439-1:2011. The provisions of the
general rules dealt with in IEC 61439-1:2011 are applicable to this standard where they are
specifically cited. When this document states "addition", "modification" or "replacement", the
relevant text in IEC 61439-1:2011 is to be adapted accordingly.
Subclauses that are numbered with a 701 (702, 703, etc.) suffix are additional to the same
subclause in IEC 61439-1:2011.
Tables and figures in this document that are new are numbered starting with 701.
New annexes in this document are lettered AA, BB, etc.
In this standard, the term ASSEMBLY written in small capitals is defined in 3.1.1 of IEC 61439-
1:2011.
The reader’s attention is drawn to the fact that Annex EE lists all of the "in-some-country"
clauses on differing practices of a less permanent nature relating to the subject of this
standard
A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and
controlgear assemblies, can be found on the IEC website.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

Damage to the finish, small dents and small chips which do not adversely affect the protection
against electric shock or harmful ingress of water should be disregarded.
Cracks passing through the material not visible with normal or corrected vision without
magnification, surface cracks in fibre-reinforced mouldings and small indentations are
disregarded.
After the test, inspection shall verify that the specified IP code and dielectric properties have
been maintained and removable covers can still be removed and reinstalled, doors opened
and closed.
10.2.701.3 Verification of resistance to static load
The following tests shall be carried out on ASSEMBLIES classified as 5.701.1.1 (ground- and
floor-mounted) intended to be installed in non-restricted access areas and restricted access
areas classified as 5.702.2 (medium resistance) or 5.702.3 (high resistance).
Test 1: an evenly distributed load L :
– 4 500 N/m for medium-resistance ASSEMBLY (see 5.702.2),
– 8 500 N/m for high-resistance ASSEMBLY (see 5.702.3),
shall be applied for 5 min to the roof of the enclosure (see Figure 701). To distribute the force
transmission on an uneven roof, a sandbag or similar device can be used.
Test 2: a force F :
– 600 N for medium resistance ASSEMBLY (see 5.702.2),
– 1 200 N for high resistance ASSEMBLY (see 5.702.3),
shall be applied for 5 min in turn to the two roof edges having the longest length (see Figure
701) except where the enclosure height exceeds 1,80 m above ground level, in which case
the force shall be applied to the front and rear sides of the enclosure located at 1,80 m above
ground level.
Where the shape of the roof is not rectangular, the two applications shall be as close as
practical to 180° of angular displacement from each other.
The force shall be transmitted over an area of not less than 100 mm × 100 mm and not
exceeding 120 mm × 120 mm.
The load/force should be applied smoothly without jerks within 30 sec. The verification of the
test starts when the load/force has been settled.
Compliance is checked by verification after the test that the minimum degree of protection is
in accordance with 8.2.2, and the operation of the door(s) and locking points are not impaired;
also by verification that the electrical clearances have remained satisfactory for the duration
ASSEMBLY having metallic enclosure, that no contact
of the tests and in the case of an
between live parts and the enclosure has occurred caused by permanent or temporary
distortion.

10.2.701.4 Verification of mechanical strength of doors
The test applies to all types of ground mounted ASSEMBLIES having a door(s) hinged on a
vertical edge of the enclosure.
This test does not apply for doors inside the enclosure and for hinged lids inside the
enclosure.
The tests shall be carried out with the door(s) fully open and in contact with the designed
restraint (see Figure 702). A load of 50 N shall be applied at the top edge of the door
perpendicular to the plane of the door(s) and at a distance of max. 300 mm from the hinged
edge and maintained for 3 s. The test is not applicable if the doors are less than 300 mm
wide.
Unless the door(s) are designed to be unhinged without the use of a tool for maintenance or
operational use, the test shall then be repeated with the force F increased to
– 250 N for medium resistance ASSEMBLY (see 5.702.2);
– 450 N for high resistance ASSEMBLY (see 5.702.3).
Compliance is checked by verification that the door(s) have not become unhinged and the
operation of the door(s), hinges and locking points are not impaired by the application of a
force of 50 N. In addition, by verification that the degree of protection remains in accordance
with 8.2.2 after the door(s) have been closed following tests. If the door(s) become unhinged
during the F test, this is not regarded as a failure if it is possible to reinstall the same door(s)
without the use of a tool.
NOTE Small cracks, created by air bubbles that were visible before the test, but not affected by the application of
the axial load, are ignored.
