42 FOREWORD
43 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising all
44 national electrotechnical committees (IEC National Committees). The object of the IEC is to promote international co-
45 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
46 other activities, the IEC publishes International Standards. Their preparation is entrusted to technical committees; any
47 IEC National Committee interested in the subject dealt with may participate in this preparatory work. International,
48 governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The IEC
49 collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions
50 determined by agreement between the two organizations.51 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an international
52 consensus of opinion on the relevant subjects since each technical committee has representation from all interested
53 National Committees.54 3) The documents produced have the form of recommendations for international use and are published in the form of
55 standards, technical specifications, technical reports or guides and they are accepted by the National Committees in that
56 sense.57 4) In order to promote international unification, IEC National Committees undertake to apply IEC International Standards
58 transparently to the maximum extent possible in their national and regional standards. Any divergence between the IEC
59 Standard and the corresponding national or regional standard shall be clearly indicated in the latter.
60 5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
61 declared to be in conformity with one of its standards.62 6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent
63 rights. The IEC shall not be held responsible for identifying any or all such patent rights.
64 International Standard IEC 60652 has been prepared by IEC technical committee 11: Overhead lines.
65 This second edition cancels and replaces the first edition, published in 1979, and constitutes
66 a technical revision.67 The text of this standard is based on the following documents:
FDIS Report on voting
11/167/FDIS 11/168/RVD
69 Full information on the voting for the approval of this standard can be found in the report on voting
70 indicated in the above table.71 This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
72 The committee has decided that the contents of this publication will remain unchanged until 2004. At this
73 date, the publication will be74 • reconfirmed;
75 • withdrawn;
76 • replaced by a revised edition, or
77 • amended.

84 1. Scope
85 This International Standard specifies the methods and procedures of testing supports for overhead
86 lines.87 It is applicable to the testing of supports and structures of overhead lines.
88 There is no restriction on the type of material used in the fabrication of the supports which may
89 include, but not be limited to, metallic alloys, concrete, timber, laminated wood and composite
90 materials. If required by the client, this standard may also be applied to the testing of
91 telecommunication supports, railway/tramway overhead electrification supports, electrical substation
92 gantries, street lighting columns, wind turbine towers, ski-lift supports, etc.
93 Tests on reduced scale models of supports are not covered by this standard.94 2. Normative references
95 The following referenced documents are indispensable for the application of this document. For dated
96 references, only the edition cited applies. For undated references, the latest edition of the referenced
97 document (including any amendments) applies.98 IEC 60050(466):1990, International Electrotechnical Vocabulary (IEV) – Chapter 466: Overhead lines

111 failure load

113 NOTE It is also known as the limit state failure load and is determined during a destruction test on the support.
114 1.4 3.4115 Realignment
116 Realignment is the process used for restoring the original ‘vertical’ position of the tower after being
117 permanently deformed due to an intermediate loading case testing. This process usually requires
118 release of bolts in connections, pulling back the tower to its original position, and finally re-tightening
119 bolts. This procedure is not recommended.120 1.5 3.4
121 test report
122 document summarizing all the relevant aspects of the tests
123 4. Categories of tests
124 The objective of support tests is to verify the design method and inherent assumptions, the method of
125 member detailing and the quality of fabrication, manufacture and material.126 With respect to the purpose of the test, the level of instrumentation and the method of execution, this
127 standard refers to two categories of tests:128 a) design tests;
129 b) sample tests.
130 4.1 Design tests
131 Design tests are normally carried out on prototype supports, with one or more of the following
132 objectives:133 a) as part of a research and/or development programme in the design of an innovative support;
134 b) to verify compliance of the support design with the specifications (also known as type tests on a
135 prototype support);136 c) to develop and/or validate a new design standard or methodology;
137 d) to develop and/or validate new fabrication processes.
138 When tests are carried out to verify design parameters, the test support shall be identical as far as
139 possible to the serial production supports (see clause 5, first paragraph). Tests on full scale sections
140 or part of the support may also be undertaken.141 Design tests shall be carried out to at least the design load or to failure, especially when testing
142 according to 4.1b) and/or 4.1c).143 4.2 Sample tests
144 These are intended for use either prior to or during the fabrication of the production of a batch of
145 supports to act as a check on the quality of the fabrication, or on the materials being used. The
146 support shall be taken at random from the serial production supports during manufacture. The test
147 constitutes the acceptance of the production.148 Sample tests are taken to a specific percentage of the design load (usually 100 %), as stipulated in
149 the test specification.150

151 5. General test criteria
152 For a design test (according to 4.1b) or 4.1c)), the material(s) and the manufacturing processes used
153 in the fabrication of the prototype support shall be to the same specifications as those used during the
154 serial fabrication of the supports. These specifications shall include the member sectional properties,
155 connection details, e.g. bolt or weld sizes, material grades and fabrication processes. Prior to the
156 commencement of the prototype support fabrication, agreement shall be made with regard to the
157 surface coating of the support.158 Agreement shall also be made with respect to the organization responsible for the checking of the
159 support prior to the testing.160 If a sample test is required on a production support, the components may be chosen at random from
161 the batch.162 Whether it is for the design test (according to 4.1b)) or the sample test, the support shall successfully
163 withstand the loads specified by the client.164 6. Acceptability of test station
165 If required by the client, the testing station shall be accredited by an external organization to
166 perform this type of test according to the procedures of quality assurance defined by ISO/IEC
167 17025.168 The following minimum requirements shall be fulfilled by the test station:
169 – the layout of the station is generally safe (e.g. in case of structure collapse the control building and
170 the observation area are not located in the danger zone)171 – the station has adequate provision to limit the severity of the collapse of the tower in the event of a
172 failure (e.g. back-stays or others)173 – all personnel is provided with adequate personal safety equipment, have received proper training,
174 and all procedures has been validated from the safety point of view175 – all lifting equipment has been regularly maintained, tested and certified
176 – the station pad is clear of loose material during the test
177 – the rigging equipment is well maintained (e.g. pulley blocks greased), tested and certified
178 – the load application dev...
