Overview

EN 50525-2-22:2011 is a European standard published by CENELEC (CLC), specifying the requirements for low voltage energy cables with rated voltages up to and including 450/750 V (U₀/U). Specifically, this standard addresses high flexibility braided cables with crosslinked elastomeric insulation, designed for general applications. The standard applies to flexible cables insulated with crosslinked ethylene propylene rubber (EPR) and covered by a textile braid. With a rated voltage of 300/300 V and a maximum conductor operating temperature of 60°C, these cables are primarily used to connect domestic appliances where extra flexibility is essential.

EN 50525-2-22 forms part of the broader EN 50525 series and should be used in conjunction with EN 50525-1, which outlines general cable requirements. It partially supersedes the older HD 22.14 S3:2007 standard.

Key Topics

• Cable Construction: The cables covered feature class 6 flexible conductors, EPR insulation, textile fillers, and an external textile braid offering high flexibility and durability.
• Rated Voltage: Intended for applications up to 300/300 V.
• Insulation and Braid: EPR (ethylene propylene rubber) insulation provides resistance and reliability, while the textile braid increases flexibility and mechanical protection.
• Testing and Compliance: Requirements include electrical tests, dimensional checks, textile braid coverage, insulation thickness, and mechanical strength tests (e.g., flexing and kink resistance).
• Identification and Marking: Compliant cables are marked with the CENELEC code H03RT-H for easy identification.

Applications

EN 50525-2-22 cables are specially designed to meet the needs of situations where extra flexibility and mechanical protection are required, making them ideal for:

• Domestic Appliances: Used to connect equipment such as vacuum cleaners, mixers, irons, and other handheld or movable household devices to the fixed supply.
• Small Machinery and Portable Tools: Suitable for environments requiring frequent movement or regular handling.
• General Indoor Use: Applicable wherever flexible, robust cables are necessary for linking appliances to the power supply.

Safety note: Extensive guidance on the safe use of these cables is provided in HD 516, which should be consulted to ensure correct installation and maintenance.

Related Standards

For a comprehensive understanding and proper application of EN 50525-2-22, the following standards are also relevant:

• EN 50525-1: General requirements for low voltage energy cables of rated voltages up to and including 450/750 V (U₀/U).
• EN 50363-1: Specifies crosslinked elastomeric insulating compounds for low voltage cables.
• EN 50395: Details electrical test methods for low voltage energy cables.
• EN 50396: Outlines non-electrical test methods such as dimensional and mechanical testing.
• EN 60228: Specifies requirements for conductors of insulated cables.
• HD 516: Provides guidance on the use of low voltage harmonized cables.
• EN 60719 & EN 60811-2-1: Offer additional methods for dimensioning and special tests for elastomeric materials.

Practical Value

Adherence to EN 50525-2-22 ensures that flexible braided cables are robust, safe, and suitable for demanding domestic and light industrial conditions. By standardizing construction, marking, and testing, the document guarantees consistent performance, enhanced safety, and interoperability across the European market for low voltage flexible cables. This standard is essential for manufacturers, installers, and specifiers seeking compliance and optimal cable performance in applications requiring both flexibility and reliability.
