DIN EN 12446:2011-09

This European Standard specifies the material, dimensional and performance requirements for factory made concrete outer wall elements for chimneys including outer wall fittings. The standard covers elements having up to four passages designated to accommodate a combination of flue liners and or air ducts. This European Standard also relates to storey-height and reinforced outer wall elements. This standard does not apply to structurally independent (freestanding or self-supporting) chimneys constructed using these outer wall elements. This standard incorporated the general requirements criteria from EN 1443:2003 and the general test methods in 13216:1:2004
