This European Standard describes test methods for metal chimney products.

This document specifies the performance requirements for rigid or flexible metal flue liners, rigid metal
connecting flue pipes and their fittings used to convey the products of combustion from appliances to the

Rigid flue liners can be used as flue liners for renovation or adaptation of existing chimneys and as flue liners
of custom built chimneys.
Flexible metal flue liners described in this document are exclusively for renovation or adaptation of existing
chimneys. Flexible connecting flue pipes and extensible flexible products designed to be compressed or
extended along their length are excluded from the scope of this document.
This document also specifies the requirements for marking, manufacturer's instructions, product information
and evaluation of conformity.
Single wall and multi-wall system chimney products are covered by EN 1856-1.

This European Standard specifies the performance requirements for single- and multi-wall system chimney products with rigid metallic liners (chimney sections, chimney fittings and terminals, including supports) with nominal diameter up to and including 1200 mm, used to convey the products of combustion from appliances to the outside atmosphere. It also specifies the requirements for marking, manufacturer's instructions, product information and evaluation of conformity. Metal liners and metal connecting flue pipes not covered here are included in EN 1856-2:2009.

It also specifies the requirements for marking, manufacturer's instruction, product information and evaluation of conformity.
NOTE 1   Recommendations for preferred dimensions of products are given in the informative Annex A.
NOTE 2   In this European Standard, only general requirements are specified for elastomeric and plastic components. Elastomeric and plastic products used in flue systems are covered by separate standards, i.e. EN 14241-1 and EN 14471.
nformity.

This standard specifies the requirements and test methods for positive pressure air/flue terminals with metal flue ducts for C62- and C63-type gas appliances, which convey air for combustion, and the products of combustion from appliances to the outside atmosphere.
It also specifies the requirements for marking, manufacturer’s instructions, product information and evaluation of conformity.
NOTE   The classification of gas appliances is according to CEN/TR 1749.

This document specifies the characteristics of performance for rigid or flexible metal flue liners, rigid metal connecting flue pipes and their fittings used to convey the products of combustion from appliances to the outside atmosphere (including their supports).
This document specifies sootfire resistant flue liners, connecting flue pipes and fittings for combustion appliances burning solid, liquid and gaseous fuels and non-sootfire resistant flue liners, connecting flue pipes and fittings for combustion appliances burning liquid and gaseous fuels only.
NOTE      This means that flue liners, connecting flue pipes and fittings designated "O" are not suitable for combustion appliances burning solid fuel.
Vitreous enamelled connecting flue pipes are also covered by this document.
Rigid flue liners can be used as flue liners for renovation or adaptation of existing chimneys and as flue liners of custom built chimneys.
