Overview

EN 50525-2-12:2011 is a CENELEC part standard in the EN 50525 series for low voltage energy cables. While the series title covers rated voltages up to 450/750 V (U0/U), this Part specifically applies to thermoplastic (PVC) insulated and PVC sheathed extensible leads rated up to and including 300/500 V (U0/U). It covers both circular and flat extensible leads intended primarily for the connection of domestic appliances to the fixed supply. Maximum conductor operating temperature is 70 °C. The standard should be read with EN 50525-1 (general requirements) and is intended to ensure safe, traceable and mechanically reliable extensible leads (coiled/helical cables).

Key topics and requirements

• Cable types and codes: Defines CENELEC codes for light and ordinary duty extensible leads:
  • Light duty: H03VVH8-F, H03VVH2H8-F
  • Ordinary duty: H05VVH8-F, H05VVH2H8-F
• Construction details:
  • Conductors: Class 5 flexible conductors per EN 60228.
  • Insulation: PVC compound Type TI 2 (EN 50363-3).
  • Sheath: PVC compound Type TM 2 (EN 50363-4-1).
  • Specified conductor sizes for circular and flat designs (e.g., 0.5 mm², 0.75 mm², 1.0 mm², 1.5 mm²).
  • Pre-coiling and post-coiling construction and marking rules, including additional coiler identification (Annex A).
• Dimensional and electrical limits:
  • Specified insulation and sheath thicknesses and minimum insulation resistance at 70 °C (see Annex D tables).
  • Voltage and insulation resistance tests on cores and completed cables.
• Testing and performance:
  • Pre-coiling and post-coiling test regimes (electrical, dimensional, material, mechanical).
  • Mechanical tests for extensible leads: extension and endurance tests (Annex F).
  • Compatibility, ageing and impact tests (e.g., ageing at 80 °C for compatibility; impact at −5 °C).
• Traceability and marking: Post-coiling marking requirements to identify the coiler and maintain traceability.

Applications and who uses it

• Intended users:
  • Cable and extensible lead manufacturers
  • Appliance OEMs specifying connection leads
  • Test laboratories and certification bodies
  • Procurement and compliance teams in electrical equipment firms
• Typical applications:
  • Coiled extension leads for domestic appliances (irons, small kitchen appliances, etc.)
  • Flexible leads where retractable/helical form is required for user convenience and strain reduction
• Benefits:
  • Ensures safe low-voltage connections, mechanical durability for repeated extension, and material compatibility for long-term use.
