This European Standard shall be given the status of a nation
28、al standard, either by publication of an identical text or by endorsement, at the latest by January 2007, and conflicting national standards shall be withdrawn at the latest by January 2007. This document supersedes EN 1806:2000. This document has been prepared under a mandate given to CEN by the Eu
29、ropean 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 integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards or
30、ganizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania,
31、Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 1806:2006 (E) 6 1 Scope This European Standard specifies the requirements for clay/ceramic flue blocks with solid walls or walls with vertical perforations including bonding and non-bonding blocks and their fittings. Non-bonding f
32、lue blocks which have insulation in the vertical perforations or attached to the outer walls are also covered by this standard. This standard specifies the performance requirements for factory-made flue blocks. When they are installed, they will form a part of a multi-wall chimney or a complete chim
33、ney which will serve to convey products of combustion from fireplaces or heating appliances to the atmosphere. This standard includes components used for domestic and industrial chimneys which are not structurally independent (free-standing). Testing, marking and inspection requirements are covered
34、by this standard. NOTE 1 Flue blocks covered by this standard are manufactured in three forms : a) single flue ; b) multi-flue ; c) flue/ventilation combination. NOTE 2 Flue blocks may have flues which are either circular, square or rectangular. The joints may have a locating feature such as a rebat
