TESTING OF METAL CHIMNEYS

Accredited initial type test according to EN 1856-1 and EN 1859

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

• Compressive strength of fittings
• Console compressive strength
• Tensile strength
• Flexural tensile strength
• Wind load
• Gas tightness
• Thermal performance test
• Terminal flow resistance
• Aerodynamic behaviour of terminal under wind conditions
• Thermal resistance (calculated)
• Flow resistance of fittings (calculated)
• Dimensions and tolerances
