ChimneyLab Europe have more than 20 years experience in type testing chimneys and related products for CE-certification

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
