20、7-1:2015EN 16497-1:2015 (E) 4 Foreword This document (EN 16497-1:2015) 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 en
21、dorsement, at the latest by August 2015 and conflicting national standards shall be withdrawn at the latest by November 2016. 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 ide
22、ntifying any or all such patent rights. 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 Regulations. For relationship with EU Regulations, see informative Annex ZA, which is an
23、integral part of this document. This standard is one of a series of co-ordinated standards dealing with specification, design, and testing 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 o
24、f a series of specifications and execution documents dealing with design and installation of concrete chimney products and systems. 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

26、alanced flue applications NOTE A chimney in accordance with EN 16497-1 can also be used for room-sealed applications using a separate combustion air supply in a non-balanced flue configuration. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following c
27、ountries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
28、 Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. BS EN 16497-1:2015EN 16497-1:2015 (E) 5 1 Scope This European Standard specifies the materials and the dimensional and performance requirements for straight concrete system chimneys for non-bal
29、anced flue applications comprising a concrete flue liner and a combination of compatible chimney components, which may be concrete flue blocks (see Clause 4), obtained or specified from one manufacturing source with product responsibility for the whole chimney. This European Standard does not apply
30、to concrete system chimneys with back ventilation. This European Standard does not cover products designated wet (W) in conjunction with corrosion class 3. This European Standard also applies to concrete system chimneys constructed from storey-height elements and flue blocks reinforced for handling.

In the context of this standard the term flue block means a vertical element of a system chimney which may also comprise the following items where appropriate: flue blocks in accordance with EN 1858; flue liners in accord
44、ance with EN 1857; insulation layer; outer wall elements in accordance with EN 12446, or EN 13069, or of appropriate metal; mortar for jointing flue liners; mortar for jointing a flue block or outer wall elements; terminal in accordance with TS 16134; chimney base; cladding; opening section; reinfor

See Annex B for examples of typical flue block types. Flue blocks shall have a maximum of fou
46、r flues or ventilation passages. 5 Materials 5.1 General The wall or walls of concrete flue liners or concrete flue blocks shall be precast concrete. For multi-wall concrete flue blocks the concrete liner and outer wall may be separated by an air space or insulation. Materials used in the manufactur
47、e of system chimneys shall be identified for factory production control purposes. When insulation forms part of a system chimney, it shall be of bonded material as specified by the manufacturer. If the insulation is supplied as a separate item, it shall be installed in accordance with the system chi
48、mney manufacturers installation instructions. The density of any insulation and the bulk density of the concrete elements shall be declared and when tested to A.11 the density shall be within 10 % of the declared value (see 8.10). Where a system chimney to this standard comprises CE marked chimney c
49、omponents in accordance with Clause 4, the above requirements are deemed to be satisfied. Products bearing regulatory marking in accordance with appropriate harmonized European specifications may be presumed to have the performances declared in the Declaration of Performance (DoP), although this does not replace the responsibility on the concrete system chimney manufacturer to ensure that the concrete system chimney as a whole is correctly manufactured and its component products have the declared perfo
