TESTING OF RIGID LINERS

Accredited initial type test accordingly to EN 1856-2

Typical test sequence for a negative pressure (N1), dry (D) rigid liner:

  • Compressive strength of fittings
  • Thermal performance test
  • Terminal flow resistance
  • Aerodynamic behaviour of terminal under wind conditions
  • Thermal resistance (calculated)
  • Flow resistance of fittings (calculated)
  • Dimensions and tolerances
