CEN/TC 297/WG 3 - Steel chimneys

This European Standard deals with steel products for single wall steel chimneys and liners which are produced either in series or as single items. It is a product standard which specifies the performance requirements of cylindrical steel fabrications for use in single wall steel chimneys and steel liners for free-standing chimneys used to convey the flue gas to the outside atmosphere. It also specifies the requirements for insulation and cladding being part of the single wall steel chimney and liner. It provides for the evaluation of conformity of single wall steel chimneys and liners to this European Standard.

This document describes the method of specifying the design criteria and the installation method for a free-standing mast with satellite pipes using welded pipes in accordance with prEN 13084-7 or using prefabricated metal chimney elements in accordance with Table D.1 of EN 1856-1:2003.

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.

TC - Modification to Table 4.

This European Standard is a product standard which specifies the performance requirements of cylindrical steel fabrications for use in single wall steel chimneys and steel liners for free-standing chimneys used to convey the flue gas from appliances to the outside atmosphere. It specifies also the requirements for insulation and cladding being part of the single wall steel chimney and liner, it provides for the evaluation of conformity of steel chimney/liners to this EN.
It is essential that the steel chimneys/steel chimney products manufactured in accordance with this European Standard comply with the requirements given in EN 13084-1 and ENV 1993-3-2.
