1 Scope 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

The single wall steel chimney and steel liner should be considered in the same way for design and requirements. SIST EN 13084-7:2013



EN 13084-7:2012 (E) 6 4 Requirements
4.1 General For the purposes of this document, EN 13084-6 applies. The products of single wall steel chimney and liner manufactured in accordance with this European Standard shall comply with the requirements given in EN 13084-1 and EN 1993-3-2. The design of steel chimneys should be covered by the Eurocodes dealing with chimneys and the requirements should be based on design and intended end use. 4.2 Performance characteristics 4.2.1 Mechanical resistance and stability Mechanical resistance and stability shall be verified in accordance with EN 1993-3-2 taking into account the characteristic values given in Tables 1 to 3 in this standard. 4.2.2 Resistance to fire Resistance to fire relates only to a soot-fire occurring within the chimney.
A chimney could convey air and/or different type of gases (see EN 13084-1). Soot-fire resistance shall only be verified for products conveying within the flue gas emitted for solid combustibles.
The resistance to fire shall be verified in accordance with EN 13084-6. If the product has been designed to be soot fire resistant, the product designation is “G”, otherwise the designation is “O”. 4.2.3 Gas tightness/Leakage The product shall be gas tight and the class H0 shall be declared in accordance with EN 13084-6. In order to meet this requirement, the design shall be in accordance with EN 13084-6, and the manufacture shall be in accordance with the qualities and controls stated in this standard. 4.2.4 Flow resistance The mean roughness value for steel to carry out flow calculations shall be declared in accordance with EN 13084-1:2007, Table A.3. The individual resistance coefficient of some forms is given in EN 13084-1:2007, Table A.4. 4.2.5 Dimensioning/Thermal resistance Flow calculations shall be carried out in accordance with EN 13084-1. The thermal resistance shall be calculated on the basis of EN 13084-1:2007, A.2.2. NOTE Dimensions related to stability are calculated on the basis of 4.2.1.
4.2.6 Thermal shock resistance Generally, thermal shock resistance is not applicable to steel because rapid changes of temperature have no significant effect on steel chimneys and liners. For specific applications (such as turbines) thermal shock may be relevant and expert advice should be sought. SIST EN 13084-7:2013



EN 13084-7:2012 (E) 7 4.2.7 Resistance to freeze-thaw Resistance to freeze-thaw is not relevant to steel chimneys and steel liners. 4.3 Durability The class of chemical attack shall be declared in accordance with EN 13084-1. Durability to chemical attack is covered by use of materials shown in Table 4. Other steels may be used provided their durability to the relevant chemical attack is demonstrated. Durability may also be achieved by other means including additional coatings and linings.
4.4 Dangerous substances National regulations on dangerous substances may require verification and declaration on release, and sometimes content, when construction products covered by this standard are placed on those markets. In the absence of European harmonised test methods, verification and declaration on release/content should be carried out, taking into account national provisions in the place of use. NOTE An informative database covering European and national provisions on dangerous substances is available at the Construction web site on EUROPA accessed through: http://ec.europa.eu/enterprise/construction/cpd-ds/. 5 Materials 5.1 Steels The steel chimneys or liners shall be made of the steels listed in Tables 1 to 4. In addition, other steels may be used in accordance with EN 13084-6:2004, Clause 4.

5.3 Insulation The insulating material shall be in accordance with the requirements given in EN 13084-1:2007, 4.4. 5.4 Cladding Cladding materials shall be suitable for the environment to which they are exposed. 6 Construction 6.1 Tolerances Tolerances shall comply with EN 13084-6:2004, 7.1. The minimum gauge length shall be 150 mm (λg of EN 1993-1-6). NOTE This is a deviation from λg of EN 1993-1-6. 6.2 Welding The manufacturer of liners shall be in accordance with EN 1090-2, EXC 2. The manufacturer of single wall chimneys shall be in accordance with EN 1090-2, EXC 3. All butt welds shall be full penetration and continuous. All welding on liners shall be at least in accordance with EN ISO 5817, Quality level “D”. Larger long pores are not permitted. All welding on single wall chimneys shall be at least in accordance with EN ISO 5817, Quality level “C”. 6.3 Construction details Where apertures are cut in the shell plates, the corners shall be radiused in accordance with EN 13084-6. Flanges and opening reinforcement to the liner shall be continuously welded.
The liner shall be continuously welded to its base plate and this in turn to any gussets or reinforcing components. Stiffening rings can have intermittent welding if permitted by the design. However, crevices exposed to weather or flue gases shall be sealed against corrosion. 6.4 Insulation Insulation shall be adequately supported to stop it from slipping and/or sagging. This can be achieved by pinning and/or banding.

EN 13084-7:2012 (E) 13 Where insulation is not covered by cladding, it shall be covered with wire mesh, or cloth, or aluminium foil etc. Insulation shall be applied in such a manner to minimise any gaps at the seams. If insulation is applied in two or more layers, all joints shall be staggered to minimise heat-loss. 6.5 Cladding Cladding shall be manufactured and fitted in such a manner as to allow for differentials in thermal expansions and prevent the ingress of weather. Cladding shall be adequately supported and fixed by riveting or screwing. 7 Evaluation of conformity 7.1 General 7.1.1 Introduction The compliance of cylindrical steel fabrications with the requirements of this standard and with the stated values (including classes) shall be demonstrated by:  Initial type testing,  Factory production control by the manufacturer, including product assessment as described in 4.2 and 4.3.
7.1.2 Initial type testing Initial type testing shall be performed to show conformity with this standard. Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account.
NOTE Component products CE marked in accordance with appropriate harmonised European specifications may be presumed to have the performances stated with the CE marking, although this does not replace the responsibility of the chimney designer to ensure that the chimney as a whole is correctly designed and its component products have the necessary performance values to meet the design. All characteristics listed above in Clauses 4 and 5 shall be subject to Initial type testing, i.e. checking of calculations and drawings, raw materials, welding procedures and qualification of welders, resistance to fire, gas tightness/leakage, flow resistance, dimensioning/thermal resistance, thermal shock resistance, flexural tensile strength, compressive strength, resistance to freeze-thaw and durability. 7.1.3 Further type testing Whenever a change occurs in the chimney, the raw material or the supplier of the components, or the production process, which would change significantly one or more of the characteristics, the type tests shall be repeated for the appropriate characteristic(s). 7.2 Factory production control 7.2.1 General The manufacturer shall establis
