Foreword
This document (EN 1857:2003) has been prepared by Technical Committee CEN /TC 166,
"Chimneys" the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2004, and conflicting national standards shall
be withdrawn at the latest by April 2005.
This document has been prepared under a mandate given to CEN by the European Commission and
the European Free Trade Association and supports essential requirements of EU Directives.
For the relationship with the EU Directives, see informative Annex ZA, which is an integral part of this
standard.
This standard is one of a series of standards dealing with the specification, design, testing and execution
of chimneys with concrete liners, both single and multi wall.
The co-ordinated package of standards is further divided by material of construction and this European
Standard is one of a series of specifications and execution documents dealing with design and execution
of concrete chimney products and systems.
The standards in this series for concrete chimney products are :
EN 1857, Chimneys - Components - Concrete flue liners
EN 1858, Chimneys - Components - Concrete flue blocks
EN 12446, Chimneys - Components - Concrete outer wall elements
In this European Standard the Annexes A, C and D are normative and Annexes B and ZA are informative.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech
Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg,
Malta, Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
1 Scope
This European Standard specifies the material, dimensional and performance requirements, including
methods of test, for factory-made concrete flue liners and fittings for the construction of multi-wall
chimneys.
This standard also applies to storey-height and reinforced flue liners.
NOTE 1 Classes in this standard, unless otherwise specified, e.g. temperature pressure, are not derived from
conditions referred to in article 3.2 of Directive 89/106/EC, and should only be considered as technical classes in the
sense of Commission Guidance Paper E ‘Levels and classes in the Construction Products Directive’.
NOTE 2 Any reference to the term flue liners implies both flue liners and their fittings, except where otherwise
indicated.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references subsequent amendments to, or revisions of, any of these publications
apply to this European Standard only when incorporated in it by amendment or revision. For undated
references the latest edition of the publication referred to applies (including amendments).

4.1 Materials
Flue liners shall be precast concrete.
Materials used shall be identified for factory production control purposes.
NOTE 1 Additions may include glass or steel fibres.
NOTE 2 Attention is drawn to Commission decision 96/603/EC, as amended, in which non-combustible
masonry units containing not more than a mass or volume fraction of 1 % (whichever is the more onerous) of
homogeneously distributed organic materials are classified as reaction to fire class A1 without testing.
4.2 Designations and classes
4.2.1 General
Flue liners shall be designated according to clause 9.
Designation classes for flue liners for temperature, pressure, resistance to soot fire, condensate
resistance and corrosion resistance shall be according to 4.2.1 to 4.2.5.
Abbreviated designations for common types of flue liners, according to temperature, pressure, soot fire
resistance, and condensate resistance (wet or dry conditions) are given in Table 1.
Where a flue liner is manufactured for an application not covered by the abbreviated designations A to L
the manufacturer shall declare the characteristics and appropriate designation in full as in clause 9.
