Overview
SIST EN 50525-2-72:2011 specifies requirements for electric cables – specifically, flat divisible cables (cords) with thermoplastic PVC insulation for low voltage general applications. These flexible cables, rated at 300/300 V (U0/U), are designed for use indoors as internal wiring or for direct supply connection to luminaires. The standard was developed by the Slovenian Institute for Standardization (SIST) and is identical to EN 50525-2-72:2011, forming part of the larger EN 50525 series concerned with low voltage energy cables of rated voltages up to and including 450/750 V.
This standard details construction, performance, and testing requirements for such flexible flat divisible cables, ensuring both safety and reliability for users and manufacturers.
Key Topics
Scope of Application
The standard covers flat, flexible, divisible cables insulated with thermoplastic (PVC) compounds. The cables are suitable for use at a maximum conductor operating temperature of 60°C.Types and Structure
- Two-core cables, each with a 0.5 mm² cross-sectional area
- Class 5 conductors as per EN 60228
- Inner and outer insulation layers of PVC type TI2, with outer color contrasting the inner
- Capable of being easily divided into individual conductors as needed for installation
Marking and Identification
Cables must be marked with the CENELEC code H03VH7H-F and comply with marking requirements outlined in EN 50525-1.Testing and Compliance
Includes electrical, mechanical, and constructional tests referenced by related standards (e.g., EN 50395, EN 50396, EN 60228). Testing ensures insulation thickness, separation of cores, resistance, and fire performance.
Applications
Internal Wiring
Suitable for fixed and flexible internal wiring within buildings, offering a convenient solution for connecting electrical circuits and distributing low voltage power efficiently.Direct Supply for Luminaires
Specifically intended for direct supply connections to indoor light fittings, benefiting from the cable’s flexibility, divisibility, and reliability.General Indoor Electrical Installations
The standard-compliant cables can be used for a wide variety of domestic, commercial, and light industrial indoor electrical supply applications where a flat, easily separated cable is preferred.
