Cable ties are used to manage and secure cables and wires. They can be found in different types of installations such as homes and offices, as well as telecommunication installations, hospitals, and solar plants. The requirements of cable ties vary depending on its application. For example, cable ties used in a solar plant will need to be heat resistant and able to withstand harsh environmental conditions.
The IEC has recently published a new edition of its standard IEC 62275, Cable management systems - Cable ties for electrical installations. This standard provides specifies requirements for cable ties and their fixing devices as a means used for managing and securing wiring systems in electrical installations. They can be used in other applications although additional requirements may apply.
Using this standard, cable ties are classified based on their material (metallic, non-metallic or composite components), loop tensile strength, maximum and minimum temperature, flame propagation and resistance to environmental influences such as ultraviolet light or corrosion. The standard also provides guidelines for testing.
This previous version of IEC 62275 was published in 2018. Compared with the previous edition, the new standard includes the following changes:
● scope clarification and new definitions
● possibility to carry out tensile strength tests with dead weights
● differentiation of rubber and acrylic adhesive fixings
● clarification of mechanical testing and testing of resistance to UV light for integral devices
● revised classification for metallic cable ties
IEC 62275 has been prepared by IEC Subcommittee 23A: Cable management systems which is part of IEC Technical Committee 23: Electrical accessories.
A Commented version (CMV) of IEC 62275 is available to allow for the easy identification of changes made compared to the previous editions. It also includes comments from the experts who developed the standard to explain the reasoning for the changes.
