Free-standing chimneys - Part 6: Steel liners - Design and execution
This European Standard deals with special requirements and performance criteria for the design of lining systems made of steel for free standing chimneys. It specifies the requirements for cylindrical steel liners as stated in
EN 13084-1.
This European Standard covers the design of the following three basic types of liners located in a load bearing structure:
a) base supported liner;
b) sectional liner;
c) top hung liner.
Additionally this European Standard also applies to single wall chimneys whose surface is in contact with flue gases.
Liners built from prefabricated metal chimneys in accordance with EN 1856-1 and prEN 1856-2 are installed as base supported liners with additional supports and guides as defined in this standard.

Cheminées autoportantes - Partie 6: Parois intérieurs en acier - Conception et mise en oeuvre
La présente Norme européenne traite des prescriptions particulières et des critères de performances applicables à la conception des parois intérieures en acier pour cheminées autoportantes. Elle définit les prescriptions relatives aux parois cylindriques intérieures en acier données dans l'EN 13084-1.
Ce document couvre la conception des trois types de paroi de base situés dans la structure porteuse :
a) paroi intérieure soutenue à la base ;
b) paroi intérieure en tronçons ;
c) paroi intérieure suspendue par le haut.
De plus, ce document s'applique également aux cheminées à simple paroi dont la surface est en contact avec les fumées.
Les parois réalisées à partir de conduits métalliques préfabriqués conformément à l'EN 1856-1 et l'EN 1856-2 sont installées comme parois intérieures soutenues à la base avec des supports et guides supplémentaires définis dans le présent document.
