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.
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.

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 s. The verification of the test
starts when the load/force has 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 and
by verification that the electrical clearances have remained satisfactory for the duration of the
having a metallic enclosure, that no contact between live
tests and in the case of an assembly
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 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 maximum 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
– 16 – IEC 61439-7:2022 © IEC 2022
• 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.
