Overview

SIST EN 50525-2-71:2011 is a European standard specifying requirements for thermoplastic (PVC) insulated flexible flat tinsel cables (cords) designed for general applications. These electric cables have a rated voltage of U0/U 300/300 V and are primarily intended for the flexible connection of small appliances to a fixed power supply. The standard ensures that such cables meet essential safety, mechanical, and electrical requirements appropriate for use in domestic and commercial environments.

Flat tinsel cables covered under this standard offer flexibility, making them ideal for movement-intensive applications where frequent bending occurs, such as in the leads of small electrical devices.

Key Topics

• Cable Construction:

  • Utilizes two parallel conductors, each made up of multiple strands of flattened copper or copper alloy wires helically wound on a textile core.
  • Conductors are insulated with a thermoplastic PVC compound of Type TI 2, as defined in EN 50363-3.
  • Features grooves between conductors in the insulation to facilitate separation.

• Voltage Rating:

  • Specifically for cables with a rated voltage of 300/300 V (U0/U), suitable for supplying small appliances requiring low voltage connections.

• Operating Temperature:

  • Maximum conductor operating temperature is set to 40 °C, ensuring safety and proper function within standard ambient conditions.

• Testing Requirements:

  • Includes electrical tests such as conductor resistance and insulation resistance.
  • Encompasses constructional, dimensional, and mechanical tests: bending tests (60,000 cycles) and snatch tests to ensure cable durability.
  • Fire safety is addressed by referencing flame propagation testing (EN 60332-1-2).
  • Material performance in low temperature impact tests (EN 60811-1-4).

• Marking and Traceability:

  • Cables must be marked with the CENELEC code H03VH-Y as per EN 50525-1.

Applications

SIST EN 50525-2-71:2011 is directly applicable to manufacturers and installers of electric cables for:

• Small Domestic and Commercial Appliances: Such as radios, hand-held devices, and other small electronics which require flexible power leads.
• Equipment Requiring Frequent Movement: The unique tinsel conductor design ensures sustained flexibility, suitable for devices with cords that are regularly flexed or repositioned.
• Lightweight Power Connections: Lightweight and flexible, these cables are ideal for situations where heavy cables are impractical.

These cables should not be used for fixed wiring installations or applications exposed to extreme temperatures or harsh environmental conditions beyond the standard's specified limits.

Related Standards

For the safe selection, installation, and use of flat tinsel PVC cables, consider referencing:

• EN 50525-1: General requirements for low voltage energy cables up to and including 450/750 V, for broader context and common cable requirements.
• EN 50363-3: PVC insulating compounds for low voltage cables.
• EN 50395 & EN 50396: Respectively, for electrical and non-electrical test methods for low voltage energy cables.
• EN 60332-1-2: Test for vertical flame propagation to ensure fire safety of cables.
• EN 60811-1-4: Material testing under low temperature conditions.
• HD 516: Guidance on the safe use of harmonized low voltage cables.

For ensuring compliance and safety, always consult the latest editions and national regulations referencing these standards.

Using SIST EN 50525-2-71:2011 ensures the safe, reliable, and flexible connection of small appliances, supporting quality and conformity in electrical installations using flat tinsel cables. Proper adherence to this standard fosters trust in cable performance and safety across the European and international markets.
