Overview
EN 50525-2-71:2011 is the CENELEC part standard for flat tinsel cables (cords) with thermoplastic PVC insulation intended for general applications. It applies to flexible, flat tinsel cables of CENELEC code H03VH-Y, rated at U0/U 300/300 V, primarily used to connect small appliances to a fixed supply. The standard defines constructional requirements, marking, testing procedures and operating limitations including a maximum conductor operating temperature of 40 °C.
This Part should be read together with EN 50525-1, which sets out the general requirements for low-voltage energy cables.
Key Topics
Construction
- Two parallel conductors formed from flattened wires helically wound on a textile thread.
- Conductors are insulated with a PVC compound of Type TI 2 (per EN 50363-3).
- Insulation includes grooves between cores to facilitate separation.
- Marking: cables must be identified with the CENELEC code H03VH-Y and comply with EN 50525-1 marking rules.
Electrical and dimensional requirements
- Rated voltage: U0/U 300/300 V.
- Typical insulation thickness: 0.8 mm.
- Mean overall dimensions: approximately 2.2 × 4.4 mm up to 3.5 × 7.0 mm (limits given in Table B.1 of the standard).
- Maximum conductor resistance at 20 °C: 270 Ω/km (see Table B.1).
- Minimum insulation resistance at 70 °C specified in the standard.
Testing and mechanical durability
- Test methods are referenced in Annex A and include EN 50395 (electrical tests), EN 50396 (non-electrical and mechanical tests) and EN 60332-1-2 (vertical flame test).
- Bending test: 60 000 bending cycles (120 000 single strokes) with no interruption of current; followed by a 1 500 V post-test voltage check between conductors (connected together) and water.
- Snatch test: no interruption of current during the test (per EN 50396 requirements).
Applications
EN 50525-2-71:2011 covers flexible flat tinsel cables used for:
- Connection leads for small household and portable appliances
- Lightweight cord sets and replacement cords where flexibility and compact flat form are required
Benefits for manufacturers and specifiers:
- Ensures consistent construction and safety properties for low-voltage flat cords
- Aligns product marking and testing with harmonized European requirements
- Provides clear mechanical and electrical test criteria for quality control
Related Standards
- EN 50525-1 - General requirements for low-voltage energy cables (must be read in conjunction)
- EN 50363-3 - PVC insulating compounds (Type TI 2)
- EN 50395 - Electrical test methods for low-voltage energy cables
- EN 50396 - Non-electrical and mechanical test methods
- EN 60332-1-2 - Vertical flame propagation test (1 kW pre-mixed flame)
- EN 60811-1-4 - Low temperature tests for insulating and sheathing materials
For procurement, design or compliance checks, reference EN 50525-2-71:2011 to verify construction, marking and the required suite of tests for H03VH-Y PVC insulated flat tinsel cords.
