EN ISO 14124-2:2021 is a technical standard that provides guidelines and requirements for the design, construction, and use of electrical insulation sleeving. This standard specifies the characteristics of sleeving and the test methods used to assess its properties. It also covers the marking and packaging requirements for sleeving materials.
Scope of EN ISO 14124-2:2021
The scope of EN ISO 14124-2:2021 includes all types of electrical insulation sleeving intended for use in low-voltage cables, wiring harnesses, and electrical equipment. The standard is applicable to both new and previously installed sleeving.
This standard does not provide specific recommendations for the selection of sleeving materials based on the type of electrical conductor or the environmental conditions in which the sleeving will be used. However, it does provide information on how to evaluate the performance of different sleeving materials against electrical, mechanical, and chemical stresses.
Requirements and Testing
EN ISO 14124-2:2021 sets out the requirements for dimensions, physical properties, thermal resistance, electrical insulation properties, and aging characteristics of sleeving materials. It also provides guidance on the testing methods used to determine these properties.
The standard specifies tests for tensile strength, elongation at break, heat stability, dielectric strength, flammability, and resistance to chemicals. These tests help ensure that sleeving materials meet the necessary safety and performance requirements for their intended use.
In addition, the standard defines the requirements for the identification and marking of sleeving materials, including information on the manufacturer, type of sleeving, and relevant standards or specifications.
Conclusion
EN ISO 14124-2:2021 is an important standard for manufacturers, suppliers, and users of electrical insulation sleeving. It provides comprehensive guidance on the design, construction, and performance requirements for sleeving materials. By complying with this standard, companies can ensure that their sleeving products meet the necessary safety and quality standards, thereby reducing the risk of electrical failures and maintaining the reliability of electrical systems.
It is essential for professionals in the electrical industry to stay updated with the latest standards such as EN ISO 14124-2:2021 to ensure the optimal performance and safety of electrical insulation sleeving used in various applications.
