IEC 61914:2021规定了用于在电气装置中固定电缆的电缆夹板和用于在电气装置中将电缆固定在一起的中间约束装置的要求和测试。电缆夹板在声明的情况下提供对机电力的抵抗力。本文件包括依靠制造商指定的安装表面来轴向和/或横向固定电缆的电缆夹板。 这第三版取消并取代了2015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: 测试中使用的心轴的要求在一般测试要求中进行了合理化和详细说明（第5条）； 添加衬垫的定义以及使用衬垫和其他可选部件的测试要求；增加了低压、中压和高压电缆的定义以及使用中压和高压电缆的测试要求； 增加了电镀产品的新耐腐蚀性等级； 增加了标记耐久性和易读性的新要求和测试； 增加了多根电缆夹板轴向载荷测试的新测试要求； 增加了中间约束的横向载荷试验要求。

IEC 61914:2021 specifies requirements and tests for cable cleats used for securing cables in electrical installations and for intermediate restraints used for holding cables together in formation in electrical installations. Cable cleats provide resistance to electromechanical forces where declared. This document includes cable cleats that rely on a mounting surface specified by the manufacturer for axial and/or lateral retention of cables.
This third edition cancels and replaces the second edition published in 2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:

1. requirements for mandrels used in testing rationalised and detailed in the general test requirements (Clause 5);
2. definition of liner added and test requirements where liners and other optional parts are used;
3. definitions for LV, MV and HV cables added and test requirements where MV & HV cable are used;
4. new corrosion resistance classes for plated products added;
5. new requirements and test for durability and legibility of markings added;
6. new test requirements for axial load testing of cleats for more than one cable added;
7. lateral load test requirements for intermediate restraints added.
