This European Standard shall
22、 be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2011, and conflicting national standards shall be withdrawn at the latest by March 2013. Attention is drawn to the possibility that some of the elements of this docume
23、nt may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12446:2003. The main modifications to EN 12446:2003 are: a) a revised table of heat flow values for thermal performance testing which no
24、w includes values for high pressure applications, e.g. diesel generators, b) a test method for the evaluation of Flexural strength under wind loading (clause 8.7 and Test methods clause A.2), c) a requirement to evaluate the gas tightness of passages used for combustion air (clause 8.8 and Test meth
25、ods clause A.3), d) a requirement relating to the Resistance to fire from an external source (clause 8.9), e) a requirement relating to the Release of dangerous substances (clause 8.10). This document has been prepared under a mandate given to CEN by the European Commission and the European Free Tra
26、de Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s) 89/106/EEC, see informative Annex ZA, which is an integral part of this document. This standard is one of a series of co-ordinated standards dealing with specification, design, testing and i
27、nstallation of chimneys, both single and multi wall. The co-ordinated package of standards is further divided by material of construction and this European Standard is one of a series of specifications and execution documents dealing with design and installation of concrete chimney products and syst
28、ems. The standards in this series for concrete chimney products and systems are: EN 1857, Chimneys Components Concrete flue liners EN 1858, Chimneys Components Concrete flue blocks EN 12446, Chimneys Components Concrete outer wall elements According to the CEN/CENELEC Internal Regulations, the natio
29、nal standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
30、Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom. DIN EN 12446:2011-09 EN 12446:2011 (E) 5 1 Scope This European Standard specifies the material, dimensional and performance requirements for factory made precast concrete outer wall elements for
31、 chimneys including outer wall fittings. This European Standard covers elements having up to four passages designated to accommodate a combination of flue liners and/or ventilation passages. This European Standard also relates to storey-height and reinforced outer wall elements. This European Standa
32、rd does not apply to structurally independent (freestanding or self-supporting) chimneys constructed using these outer wall elements. NOTE Any reference to the term “outer wall element“ implies both the outer wall elements and their fittings, except where otherwise indicated. 2 Normative references
