BS EN 13084-7:2012EN 13084-7:2012 (E) 5 1 Scope This European Standard deals with steel products for single wall steel chimneys and liners w
25、hich 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 a
26、lso 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

33、orrected version:2005, including Technical Corrigendum 1:2006) 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 13084-1:2007 and EN 13084-6:2004 apply. The single wall steel chimney and steel liner should be considered in the same way for design and re
34、quirements. BS EN 13084-7:2012EN 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
35、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 a
36、ccordance 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-fir
37、e 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
38、 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 state
39、d 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 resistan
40、ce 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
41、 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. BS EN 13084-7:2012EN 13084-7:2012 (E) 7 4.2.7 Resistance to freeze-tha
42、w 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 durabili
43、ty 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 constru
44、ction 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
45、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
46、 may be used in accordance with EN 13084-6:2004, Clause 4.
