This European Standard specifies the performance requirements and test methods for system chimneys with plastic flue liners used to convey the products of combustion from appliances to the outside atmosphere under dry and wet conditions. It also specifies the requirements for marking, manufacturer's instructions and evaluation of conformity.This European Standard describes chimney components from which system chimneys can be assembled.This European Standard is not applicable to chimneys with sootfire resistance classification class G.This European Standard is not applicable for chimneys with the following classification:-corrosion resistance class 2 concerning natural wood );-corrosion resistance class 3;-pressure class N2.This European Standard is applicable to chimneys designed so that no condensate accumulation can occur, e.g. with a minimum inclination of 3° to the horizontal.This European Standard is not applicable-for system chimneys with plastic coated flue liners;-to structurally independent (free-standing or self-supporting) chimneys.Chimneys with components which need further processing during the installation to reach the final material properties are no system chimneys and therefore also not covered by this standard.This European Standard does not cover the requirements for horizontal terminals (as defined for C1 installation types in CEN/TR 1749) regarding aerodynamic behaviour, rainwater ingress and icing behaviour.
