Non-electrical Tests

  • Cable Construction Verification
  • Test to determine the mechanical properties of insulation before and after ageing
  • Tests to determine the mechanical properties of the outer sheath before and after ageing
  • Ageing Test on Pieces of Complete Cable
  • Loss of Mass Test
  • High Temperature Pressure Test
  • Low Temperature Test
  • Thermal Shock Test
  • Ozone Resistance Test
  • Elongation Test
  • Measurement of Insulation Density
  • Measurement of Carbon Black Content
  • Test under Fire Conditions
