Overview

EN 50525-2-11:2011 is a CENELEC (CLC) standard that specifies requirements for flexible thermoplastic PVC insulated and PVC sheathed low-voltage energy cables used to connect domestic appliances to the fixed supply. Although the EN 50525 series covers cables up to 450/750 V, this Part specifically applies to cables of rated voltages U0/U up to and including 300/500 V. It covers circular and flat flexible cables, defines conductor and material classes, maximum operating temperatures (70 °C for VV types and 90 °C for V2V2 types), and sets out mandatory tests and marking.

Key Topics

• Cable types and CENELEC codes
  • Light duty: H03VV-F, H03VVH2-F
  • Ordinary duty: H05VV-F, H05VVH2-F
  • Heat-resistant (90 °C): H03V2V2-F, H05V2V2-F, and strain-bearing H05V2V2D3-F
• Conductor and materials
  • Conductors shall be class 5 (flexible fine-stranded) per EN 60228.
  • Insulation compounds: TI2 (standard) and TI3 (heat resistant) according to EN 50363-3.
  • Sheath compounds: TM2/TM3 per EN 50363-4-1.
• Sizes and constructions
  • Sizes covered include 0.5 mm², 0.75 mm² up to 4 mm² depending on type; flat and circular constructions and core counts are defined for each code.
• Testing and quality requirements
  • Annex A lists mandatory tests: conductor resistance, voltage tests (e.g., 1 500 V / 2 000 V depending on insulation thickness), insulation resistance at operating temperatures, long-term insulation resistance, mechanical and ageing tests, and flammability tests (referenced standards).
  • Annexes B and C define dimensional data and compatibility test requirements.

Applications

• Intended primarily for power leads and flexible cords used with domestic appliances, small household equipment, extension leads, and portable tools where flexible, PVC-insulated low-voltage cables are required.
• Primary users:
  • Cable manufacturers developing compliant flexible PVC cables
  • Product designers and appliance OEMs specifying power cords
  • Test laboratories performing electrical and mechanical compliance testing
  • Procurement and conformity assessors ensuring components meet EN requirements
  • Installers and specifiers selecting flexible cables for consumer and light commercial applications

Related Standards

• EN 50525-1 (general requirements)
• EN 60228 (conductors)
• EN 50363-3 / EN 50363-4-1 (PVC insulating and sheathing compounds)
• EN 50395 / EN 50396 (electrical and non-electrical test methods)
• EN 60332-1-2, EN 60811 (fire and ageing test methods)

EN 50525-2-11:2011 is essential when specifying or manufacturing flexible PVC insulated low voltage energy cables for safe, tested, and market-compliant appliance connections.
