EN 50363-10-1:2005

Overview

EN 50363-10-1:2005 is a European standard published by CLC that specifies test requirements for cross-linked polyvinyl chloride (XLPVC) sheathing compounds used in low voltage energy cables. This part of the EN 50363 series focuses on the physical properties of harmonized XLPVC compounds, ensuring they meet strict quality criteria for durability and performance. The standard provides detailed test methods aligned with the EN 60811 series, making it essential for manufacturers and quality controllers involved in cable production.

Key Topics

• Scope and Application
  EN 50363-10-1:2005 targets miscellaneous sheathing compounds based on cross-linked PVC primarily for flexible cords, such as iron cords, operating at maximum temperatures up to 70°C. It complements EN 50363-0, which covers general requirements for insulating, sheathing, and covering materials for low voltage cables.

• Test Requirements
  The standard lists critical physical property tests including:

  • Mechanical properties before and after ageing (tensile strength and elongation at break).
  • Loss of mass and heat shock resistance.
  • Pressure resistance at elevated temperatures.
  • Bending test performance at low temperatures.
  • Thermal stability and hot set behavior under mechanical stress.

• Performance Criteria
  Specific performance thresholds ensure reliability such as:

  • Minimum tensile strength of 10 N/mm².
  • Minimum elongation at break of 150%.
  • Maximum mass loss of 2 mg/cm² after ageing.
  • No cracks after bending at -15°C.
  • Thermal stability for at least 60 minutes at 200°C.
  • Controlled hot set elongation under load.

• Test Method References
  All tests follow procedures defined in the EN 60811 series, preserving consistency and harmonization in assessing cable sheathing materials.

Applications

EN 50363-10-1:2005 is vital for manufacturers, designers, and quality assurance professionals working with low voltage energy cables that require durable sheathing compounds. Typical applications include:

• Flexible power cords and iron cords that need high mechanical flexibility and long service life.
• Electrical wiring infrastructure in residential, commercial, and light industrial environments.
• Products requiring compliance with European electrotechnical standards to ensure safety and performance.
• Cable components exposed to mechanical stress, temperature variations, and aging conditions.

Using materials tested and certified under EN 50363-10-1 supports improved cable longevity and enhanced resistance to environmental and mechanical factors, which is crucial in maintaining electrical safety and operational reliability.
