Testing of flexible liners
Accredited initial type test accordingly to EN 1856-2
Typical test sequence for a negative pressure (N1), dry (D) flexible liner:
- Compressive strength of fittings and supports
- Tensile strength
- Crushing resistance
- Flexibility
- Torsion strength
- Pulling force
- Gas tightness
- Thermal performance test
- Thermal resistance (calculated)
- Flow resistance of liner and fittings (calculated)
- Dimensions and tolerances
