IEC 62275:2022 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62275:2022 edition 4.0 and the previous IEC 62275:2018 edition 3.0. Furthermore, comments from IEC SC 23A experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 62275:2022 specifies requirements for metallic, non-metallic and composite cable ties and their associated fixing devices as a means used for managing or securing the wiring systems in electrical installations. Cable ties and associated fixing devices can also be suitable for other applications, such as support of wiring systems, and where so used, additional requirements can apply.

This edition includes the following significant technical changes with respect to the previous edition: - scope clarification, - new definitions, - deletion of the exception for the stabilization of the moisture content, - possibility to carry out tensile strength tests with dead weights, - differentiation of rubber and acrylic adhesive fixings, - clarification for mechanical testing of integral devices, - clarifications on Table 6, - clarifications in 9.1, - the minimum installation temperature test for cable ties is carried out only when the declared minimum temperature is lower than 0 °C, - a requirement that metallic cable ties be classified according to 6.2.3, - definition of colours to be tested for contribution to fire, - addition of a "some countries" note in Clause 10, - clarification of the mounting of fixing devices in the resistance to ultraviolet light test, - clarification on the testing of integral devices in the resistance to ultraviolet light test.
