Chimneys - Concrete System Chimneys - Part 2: Balanced flue applications

This European Standard specifies the materials, dimensional and performance requirements for straight concrete system chimneys for balanced flue applications comprising a concrete flue liner and a combustion air supply duct, 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.
The European Standard does not apply 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.
This European Standard does not apply to structurally independent (free standing or self-supporting) system chimneys.
NOTE   Any reference to the term flue blocks implies both flue blocks and their fittings, except where otherwise indicated.

Abgasanlagen - System-Abgasanlagen aus Beton - Teil 2: Luft-Abgas-Systeme

Diese Europäische Norm legt die Anforderungen an Werkstoffe, Abmessungen und die Leistungsfähigkeit von geraden Luft-Abgas-Systemen aus Beton fest, welche aus einem Betoninnenrohr, einem Verbrennungsluftschacht und einer Kombination von aufeinander abgestimmten Abgasanlagenbauteilen bestehen, bei denen es sich um Betonformblöcke (siehe Abschnitt 4) handeln kann, die von einem Hersteller bezogen oder definiert werden, der die Produkthaftung für die gesamte Abgasanlage übernimmt.
Die Europäische Norm gilt nicht für hinterlüftete System-Abgasanlagen aus Beton.
Diese Europäische Norm gilt nicht für Produkte, die in Verbindung mit Korrosionswiderstandsklasse 3 mit feucht (W) gekennzeichnet sind.
Diese Europäische Norm gilt außerdem für System-Abgasanlagen aus Beton, die aus geschosshohen Elementen und mit einer Transportbewehrung versehenen Formblöcken gebaut sind.
Diese Europäische Norm gilt nicht für baulich unabhängige (freistehende oder selbsttragende) System-Abgasanlagen.
ANMERKUNG   Sämtliche Verweisungen auf den Begriff "Formblöcke" beziehen sich in dieser Norm immer sowohl auf Formblöcke als auch auf ihre Formstücke, außer wenn es anders angegeben ist.

Conduits de fumée - Conduits-Systèmes de fumée en béton - Partie 2: Applications équilibrées

Le présent document spécifie les exigences relatives aux matériaux, aux dimensions et aux performances des conduits-systèmes de fumée droits en béton pour applications équilibrées comprenant un conduit intérieur en béton, un conduit d’alimentation en air comburant et des éléments manufacturés compatibles, qui peuvent être des conduits simple et multiparois en béton (voir 4), fabriqués ou spécifiés par un seul fabricant, responsable de la totalité du conduit de fumée.
Le présent document ne s’applique qu’aux conduits-systèmes de fumée ventilés par l’extérieur.
Le présent document ne couvre pas les produits désignés « humides » (W) associés à la classe de corrosion 3.
Le présent document couvre également les conduit-systèmes de fumée hauteur d’étage et les conduits armés pour la manutention.
Le présent document ne s’applique pas aux conduits-systèmes de fumée structurellement indépendants (libres ou autoportants).
NOTE   Toute référence au terme « conduit de fumée » implique l’ensemble des conduits et leurs accessoires, sauf indication contraire.

Dimovodne naprave - Betonske sistemske dimovodne naprave - 2. del: Tlačno izravnan sistem

Ta evropski standard določa materiale, mere in zahtevane lastnosti za ravne sistemske dimnike iz betona za tlačno izravnane dimniške sisteme, ki vključujejo betonske tuljave in cev za dovod zraka za izgorevanje ter kombinacijo združljivih sestavnih delov dimnikov, ki so lahko betonske tuljave (glej točko 4), pridobljene od enega proizvodnega vira, proizvodno odgovornega za celoten dimnik, ali ki jih določi ta vir.
Standard se ne uporablja za betonske sistemske dimnike s povratnim prezračevanjem.
Ta standard ne zajema mokrih (W) označenih proizvodov skupaj s korozijskim razredom 3.
Ta evropski standard se uporablja tudi za betonske sistemske dimnike iz elementov za etažno višino in tuljav, ojačanih za namene rokovanja.
OPOMBA:   Vsa sklicevanja na izraz tuljava pomenijo tuljave in njihove fitinge, razen če je navedeno drugače.

European foreword This document (EN 16497-2:2017) 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 September 2017, and conflicting national standards shall be withdrawn at the latest by December 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying 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 Directive(s). For relationship with EU Regulation, see informative Annex ZA, which is an integral part of this document. In this European Standard, the Annexes A, C and D are normative (not forming part of the product specification) and Annexes E and ZA are informative. This standard is one of a series of coordinated standards dealing with specification, design, and testing of chimneys, both single and multi wall. The coordinated 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 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 blocks; EN 12446, Chimneys — Components — Concrete outer wall elements.
