FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60652 has been prepared by IEC technical committee 11: Overhead
lines.
This second edition cancels and replaces the first edition, published in 1979, and constitutes
a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
11/167/FDIS 11/168/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged until 2004.
At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

LOADING TESTS ON OVERHEAD
LINE STRUCTURES
1 Scope
This International Standard codifies the methods of testing supports for overhead lines.
It is applicable 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 standard may 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 standard.
2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies.

3 Definitions
For the purposes of this International Standard, the following definitions apply. The definitions

listed below supplement those given in lEC 60050(466).
3.1
client
organization which contracts with the testing station and provides the test specification
3.2
design load
load for which the support has been designed

60652  IEC:2002 – 9 –
3.3
failure load
point at which the support cannot carry any additional load
NOTE It is also known as the limit state failure load and is determined during a destruction test on the support.
3.4
test report
document summarizing all the relevant aspects of the tests
4 Categories of tests
With respect to the purpose of the test, the level of instrumentation and the method of
execution, this standard refers to two categories of tests:
a) design tests;
b) sample tests.
4.1 Design tests
Design tests are normally carried out on prototype supports, with one or more of the following
objectives:
a) as part of a research and/or development programme in the design of an innovative
support;
b) to verify compliance of the support design with the specifications (also known as type
tests);
c) to develop and/or validate a new design standard or methodology;
d) to develop and/or validate new fabrication processes.
When tests are carried out to verify design parameters, the test support shall be identical as far
as pos
