6、 the date given therein. National foreword This standard has been prepared by Technical Committee CEN/TC 166 “Chimneys” (Secretariat: ASI, Austria). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee), Working
7、Committee NA 005-11-36 AA Abgasanlagen aus Keramik und Beton (SpA CEN/TC 166/SC1 und WG 3). Amendments This standard differs from DIN EN 1457:2003-04, DIN EN 1457 Corrigendum 1:2006-10, DIN EN 1457 Corrigendum 2:2007-08 and DIN EN 1457/A20:2007-09 as follows: a) the standard has been subdivided into
8、 Part 1 for flue liners operating under dry conditions and Part 2 for flue liners operating under wet conditions; b) the scope has been rendered more precise; c) the standard has been completely restructured.

The main changes with res
32、pect to the previous edition are: EN 1457 has been split in 2 parts: EN 1457-1 is a product standard for clay/ceramic flue liners operating under dry conditions. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement
33、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, Slovakia, Slovenia, Spain, Sweden, Switzerl
34、and, Turkey and the United Kingdom. DIN EN 1457-1:2012-04 EN 1457-1:2012 (E) 6 1 Scope This European Standard is a product standard for clay/ceramic flue liners operating under dry conditions with solid walls or walls with vertical perforations for use in the construction of multiwall chimneys and f
35、lue 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 (free-standing). This European Standar
36、d 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. This part does not cover flue liners operating under wet conditions. 2 Normative references T
