DIN EN 12446

Abstract

This European Standard specifies the material, dimensional and performance requirements for factory made precast concrete outer wall elements for chimneys including outer wall fittings. <br>This European Standard covers elements having up to four passages designated to accommodate a combination of flue liners and/or ventilation passages. <br>This European Standard also relates to storey-height and reinforced outer wall elements. <br>This European Standard does not apply to structurally independent (freestanding or self-supporting) chimneys constructed using these outer wall elements. <br>NOTE Any reference to the term "outer wall element" implies both the outer wall elements and their fittings, except where otherwise indicated.
