28、word This document (EN 1457-2:2012) has been prepared by Technical Committee CEN/TC 166 “Chimneys”, the secretariat of which is held by ASI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 20
29、12, and conflicting national standards shall be withdrawn at the latest by July 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights.
30、This document supersedes EN 1457:1999. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an
31、 integral part of this document. EN 1457 is made of two parts: EN 1457-1, Chimney Clay/ceramic flue liners Part 1: Flue liners operating under dry conditions Requirements and test methods; EN 1457-2, Chimney Clay/ceramic flue liners Part 2: Flue liners operating under wet conditions Requirements and
32、 test methods. The main changes with respect to the previous edition are: EN 1457 has been split in 2 parts: EN 1457-2 is a product standard for clay/ceramic flue liners operating under wet conditions. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the fol
33、lowing 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, Norway, Poland, Portugal, Romania, Slo
34、vakia, Slovenia, Spain, Sweden, Switzerland Turkey and the United Kingdom. DIN EN 1457-2:2012-04 EN 1457-2:2012 (E) 6 1 Scope This European Standard is a product standard for clay/ceramic flue liners operating under wet conditions with solid walls or walls with vertical perforations for use in the c
35、onstruction of multiwall chimneys and flue pipes which serve to convey products of combustion from fireplaces or heating appliances to the outside atmosphere by negative or positive pressure. It includes the flue liners used for domestic and industrial chimneys which are not structurally independent
36、 (free-standing). This European Standard specifies the performance requirements for factory made flue liners and chimney fittings. Testing including thermal testing with or without insulation, marking and inspection are covered by this standard. Flue liners that are specified to this standard will m
37、eet the requirements of EN 1457-1 with the same working temperature, pressure, designation and soot fire resistance. 2 Normative references The following referenced documents are indispensable for the application of this document.
