Overview
EN 50525-2-72:2011 is a CENELEC European standard that specifies requirements and tests for flat divisible flexible cables (cords) with thermoplastic PVC insulation used as low voltage energy cables. It covers flat divisible cables of rated voltage U0/U 300/300 V intended for indoor use - typically as internal wiring or for direct supply connections to luminaires. These cables are marked H03VH7H-F, have class 5 flexible conductors and a maximum conductor operating temperature of 60 °C. This Part must be read together with EN 50525-1 (general requirements) and refers to material and test standards such as EN 50363-3, EN 50395 and EN 50396.
Key topics and technical requirements
- Cable construction
- Two-core, flat, divisible design (twin parallel cores that can be separated).
- Conductors: flexible, class 5 (EN 60228).
- Insulation: inner and outer layers of PVC (Type TI 2); outer layer in a contrasting colour; outer layer may adhere to cores.
- Standard marking: H03VH7H-F per EN 50525-1.
- Electrical and mechanical limits
- Rated voltage: 300/300 V (U0/U).
- Max conductor operating temperature: 60 °C.
- Typical conductor size referenced: 2 × 0.5 mm².
- Testing requirements
- Electrical tests: conductor resistance, 2 000 V voltage test on completed cable, insulation resistance at elevated temperature.
- Mechanical/dimensional tests: thickness and overall dimension checks, flexing and separation tests.
- Environmental and safety tests: impact at −5 °C, flexing after water immersion, and vertical flame propagation test (EN 60332-1-2).
- Material tests for PVC per EN 50363-3 and non-electrical tests per EN 50396.
- Insulation checks
- Insulation thickness and insulation resistance requirements are specified; outer layer thickness measured after division of cores. Separation test ensures inner layer remains concealed after testing.
Applications
- Indoor internal wiring where a slim, flat, divisible twin cable is required.
- Direct supply connections to luminaires, lamps and lighting fixtures.
- Flexible cord applications in appliances or devices requiring separable twin conductors for simple terminations.
Who uses this standard
- Cable manufacturers and product designers specifying flat PVC insulated cords.
- Electrical installers and lighting manufacturers needing compliant connection cords.
- Test laboratories and conformity assessment bodies performing EN-type tests.
- Procurement/specification engineers and compliance officers specifying cables to harmonized European requirements.
