This European Standard shall be given the status of a national standard, either by publication of an identical text o

EN 13084-1:2007 (E) 5 1 Scope This

25、European Standard deals with the general requirements and the basic performance criteria for the design and construction of all types of free-standing chimneys including their liners. A chimney may also be considered as free-standing, if it is guyed or laterally supported or if it stands on another

26、structure. Chimneys attached to buildings have to be structurally designed as free-standing chimneys in accordance with this European Standard when at least one of the following criteria is met: the distance between the lateral supports is more than 4 m; the free-standing height above the uppermost

27、structural attachment is more than 3 m; the free-standing height above the uppermost structural attachment for chimneys with rectangular cross section is more than five times the smallest external dimension; the horizontal distance between the building and the outer surface of the chimney is more th

28、an 1 m. Chimneys attached to free-standing masts are considered as free-standing chimneys. The structural design of free-standing chimneys takes into account operational conditions and other actions to verify mechanical resistance and stability and safety in use. Detailed requirements relating to sp

29、ecialized designs are given in the standards for concrete chimneys, steel chimneys and liners. NOTE In other parts of the series EN 13084 rules will be given where chimney products in accordance with EN 1443 (and the relating product standards) may be used in free-standing chimneys. 2 Normative refe
