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.
