Overview - EN 50363-4-2:2005 (PVC covering compounds)

EN 50363-4-2:2005 is a CENELEC European standard specifying the physical property requirements for PVC covering compounds used on low-voltage energy cables. It applies to PVC sheathing/covering materials (type TM 6) and references the EN 60811 series for the relevant test methods. This part is intended to be read in conjunction with EN 50363-0 and was approved by CENELEC on 2005-11-01.

Key topics and technical requirements

The standard defines measurable requirements and test conditions for PVC covering compounds, including:

• Material type and application

  • Type: TM 6 (maximum cable operating temperature 70 °C)
  • Typical use: coverings for cold-resistant cables (cross-ref. EN 61138)

• Mechanical properties (before and after ageing)

  • Tensile strength (median, min): 7.5 N/mm²
  • Elongation at break (median, min): 125%
  • After oven ageing (80 ± 2 °C for 7 × 24 h): tensile and elongation must meet the same minima with maximum permitted variation ±20%

• Thermal and ageing tests

  • Loss of mass after ageing (80 ± 2 °C for 7 × 24 h): max 2.0 mg/cm²
  • Heat shock: 150 ± 2 °C for 1 h - result: no cracks
  • Pressure/indentation at elevated temperature (70 ± 2 °C): median depth of indentation ≤ 50%
  • Low-temperature behaviour: bending test at -40 ± 2 °C - no cracks
  • Low-temperature elongation: at -40 ± 2 °C, elongation without break ≥ 30%

• Test methods

  • All referenced test procedures are those in the EN 60811 series; cross-references and detailed procedures are given in EN 50363-0.

Practical applications and users

This standard is primarily used for:

• Cable manufacturers and compound formulators verifying PVC sheathing performance for low-voltage energy cables
• Materials suppliers and quality control laboratories performing type testing and routine quality checks
• Specifiers, procurement engineers, and project managers requiring compliant cable sheathing for installations, including cold-environment applications
• National standards bodies and conformity assessors implementing CENELEC requirements

Using EN 50363-4-2 helps ensure consistent PVC covering quality, reliable mechanical and thermal performance, and traceable testing aligned with EN 60811.
