Asnjë informacion i shtuar.

This European Standard specifies the materials, dimensional and performance requirements for concrete flue blocks as defined in clause 3 for use in system chimneys. The flue blocks may be of single wall or multi wall construction. The standard does not apply to blocks with back ventilation. The standard specifies a type of block to dimensionally co-ordinate with masonry unit coursing height, referred to as a type B (Bonding block). The standard also relates to storey-height and reinforced flue blocks. NOTE 1 Classes in this standard 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.
