IEC 60652:2021作为IEC 60652:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60652:2021规定了架空线路支架测试的方法和程序。适用于架空线路支架和结构的检测。对用于制造支撑件的材料类型没有限制，其可以包括但不限于金属合金、混凝土、木材、层压木材和复合材料。如果客户要求，本文件也可应用于电信支架、铁路/电车架空电气化支架、变电站龙门架、路灯杆、风力涡轮机塔、滑雪-升降机支架等。本文件不包括对支架缩小比例模型的测试。这第三版取消并取代了2002年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)标题修改；b)增加了对CIGRE手册399的引用；c)在条款7中，增加了测试期间风速和风向的测试限制；d)在第10.5段中，增加了破坏试验的载荷增量；e)在第10.7段中，增加了当测试由蠕变敏感材料制成的支架时，客户和测试站之间的协议要求；f)在第17条中，增加了在试验报告中提供取样程序的要求。

IEC 60652:2021 is available as IEC 60652:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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.
