Overhead line structures - Loading tests

IEC 60652:2021 specifies the methods and procedures of testing supports for overhead lines. It applies to the testing of supports and structures of overhead lines. There is no restriction on the type of material used in the fabrication of the supports which may include, but not be limited to, metallic alloys, concrete, timber, laminated wood and composite materials. If required by the client, this document can also be applied to the testing of telecommunication supports, railway/tramway overhead electrification supports, electrical substation gantries, street lighting columns, wind turbine towers, ski-lift supports, etc. Tests on reduced scale models of supports are not covered by this document. This third edition cancels and replaces the second edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) Title modified;
b) Added reference to CIGRE Brochure 399;
c) In Clause 7, added test limitation for wind speed and direction during testing;
d) In paragraph 10.5, added load increments for destruction tests;
e) In paragraph 10.7, added a requirement for an agreement between client and testing station when testing supports made of creep-sensitive materials;
f) In Clause 17, added requirements for sampling procedure to be provided in the test report.

Structures des lignes aériennes - Essais mécaniques

IEC 60652:2021 spécifie les méthodes et procédures d'essai pour les supports de lignes aériennes. Il s'applique aux essais des supports et structures des lignes aériennes. Aucune restriction ne s'applique au type de matériau utilisé pour la fabrication des supports qui peuvent, entre autres, être réalisés en alliages métalliques, en béton, en bois (éventuellement stratifié) et en matériaux composites. Si le client l'exige, le présent document peut également être appliqué dans le cadre d'essais concernant les supports de télécommunication, les supports d'électrification de lignes aériennes pour les chemins de fer/tramways, les portiques de postes électriques, les supports d'éclairage public et de signalisation, les mâts d'éoliennes, les supports de téléphériques, etc. Les essais réalisés sur modèles de supports à échelle réduite ne sont pas couverts par le présent document. Cette troisième édition annule et remplace la deuxième édition parue en 2002. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le titre a été modifié;
b) une référence à la brochure 399 du CIGRE a été ajoutée;
c) à l'Article 7, des limites d'essai ont été ajoutées pour la vitesse et la direction du vent lors des essais;
d) en 10.5, des incréments de charge ont été ajoutés pour les essais destructifs;
e) en 10.7, une exigence a été ajoutée aux essais de supports constitués de matériaux sensibles au fluage : celle-ci est soumise à l'accord entre la station d'essais et le client;
f) à l'Article 17, des exigences ont été ajoutées pour la procédure d'échantillonnage en vue d’étayer le rapport d'essai.

LOADING TESTS ON OVERHEAD LINE STRUCTURES – LOADING TESTS

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.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60652:2002. A vertical bar appears in the margin wherever a change has
been made. Additions are in green text, deletions are in strikethrough red text.

LOADING TESTS ON OVERHEAD LINE STRUCTURES – LOADING TESTS

1 Scope
This document codifies specifies the methods and procedures of testing supports for overhead
lines.
It applies to the testing of supports and structures of overhead lines for voltages above 45 kV;
it can also serve as reference to the testing of lower voltage supports.
There is no restriction on the type of material used in the fabrication of the supports which may
include, but not be limited to, metallic alloys, concrete, timber, laminated wood and composite
materials. If required by the client, this document may can also be applied to the testing of
telecommunication supports, railway/tramway overhead electrification supports, electrical
substation gantries, street lighting columns, wind turbine towers, ski-lift supports, etc.
Tests on reduced scale models of supports are not covered by this document.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies.
