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
