Accredited initial type test according to EN 1856-2

Typical test sequence for a negative pressure (N1), dry (D) connecting flue pipe:

• Compressive strength of fittings
• Tensile strength
• Gas tightness
• Thermal performance test
• Thermal resistance (calculated)
• Flow resistance of liner and fittings (calculated)
• Dimensions and tolerances
