BS EN 1858:2008+A1:2011EN 1858:2008+A1:2011 (E)5 1 Scope This European Standard specifies the materials, dimensional and performance requirements for precast concrete flue blocks as defined in Clause 3 for use in !deleted text “ chimneys.

30、 The flue blocks may be of single wall or multi wall construction. The standard does not apply to flue blocks with back ventilation. This standard does not cover products designated wet (W) in conjunction with corrosion class 3. The standard also specifies a type of flue block to dimensionally co-or

31、dinate with masonry unit coursing height, referred to as a type B (Bonding block). This European Standard also applies to storey-height and flue blocks reinforced for handling. NOTE Any reference to the term flue blocks implies both flue blocks and their fittings, except where otherwise indicated. 2

For multiwall flue blocks the liner and outer wall may be sepa

44、rated by an air space or insulation. Materials used in the manufacture of flue blocks shall be identified for factory production control purposes. When insulation forms part of a flue block, it shall be of bonded material as specified by the manufacturer. If the insulation is supplied as a separate
