Chimneys - Elastomeric seals and elastomeric sealants - Material requirements and test methods - Part 1: Seals in flue liners
This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in flue liners. It also specifies the requirements for evaluation of conformity. These seals are components in flue liners of different materials such as metal, plastic, clay, concrete. Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards. In the product standards, chimney products, including seals, are tested under operational conditions (e.g. temperature, pressure, mechanical load, flue gas, condensate) to relevant properties such as leakage and deformation. This European Standard covers seals intended for use in both dry and wet conditions. Therefore all seals are tested for functioning under wet conditions.
Abgasanlagen - Werkstoffanforderungen und Prüfungen für elastomere Dichtungen und Dichtwerkstoffe - Teil 1: Dichtungen für den Einsatz in Innenrohren
Ziel dieses Dokumentes ist es, das Werkstoffverhalten von elastomeren Dichtungen für den Einsatz in Innenrohren zu bewerten. Es spezifiziert auch Anforderungen an ein Konformitätsbewertungssystem.
Die Dichtungen sind Komponenten der Innenrohre, die aus verschiedenen Werkstoffen bestehen können, wie Metall, Kunststoff, Ton, Beton usw.
Die funktionalen Anforderungen an elastomere Dichtungen von Innenrohren sind in entsprechenden Produktnormen enthalten.
Die Produktnormen sehen für die Bauteile von Abgasanlagen einschließlich Dichtungen Prüfungen entsprechend den Einsatzbedingungen (z. B. Temperatur, Druck, mechanische Belastung, Abgas, Kondensat) relevante Eigenschaften, wie Leckage und Deformation, vor
Dieses Dokument behandelt Dichtungen, die sowohl für den Trocken- wie Nassbetrieb vorgesehen sind. Deshalb werden alle Dichtungen für den Einsatz im Nassbetrieb geprüft.
Dieses Dokument enthält nicht alle Anforderungen, denen eine Abgasanlage nach folgender Klassifikation genügen muss:
- Korrosionswiderstandsklasse 2 in Bezug auf Naturholz ) ;
- Korrosionswiderstandsklasse 3.
Die Norm ist auch auf Dichtmittel anwendbar, sofern nichts anderes festgelegt wurde. Die Prüfkörper sind dabei aus Dichtmitteln herzustellen, die in eine geeignete Form gebracht wurden und nach Herstellerangaben aushärten konnten. Die ausgehärteten Dichtmittel müssen die gleichen Anforderungen wie Dichtungen erfüllen.
ANMERKUNG Dichtmittel im ausgehärteten Zustand stellen funktionstechnisch Dichtungen in der Anwendung dar.
Conduit de fume - Garnitures et matériaux d'etanchéité en elastomère - Exigences de matériaux et méthodes d'essai - Partie 1: Garnitures d'étanchéite dans les conduits interieures
La présente Norme européenne spécifie les exigences et les méthodes d'essai des joints élastomères
préfabriqués utilisés dans les parois intérieures, ainsi que les exigences relatives à l'évaluation de la
conformité.
Ces joints sont des composants de la paroi intérieure constituée de différents matériaux tels que le métal, le
plastique, la terre cuite, le béton, etc.
Les exigences de performances des joints élastomères de parois intérieures sont traitées par les normes de
produits correspondantes.
Dans les normes de produits, les produits utilisés pour les conduits de fumée, y compris les joints, sont
soumis à des essais dans des conditions de fonctionnement (température, pression, charge mécanique,
fumées et condensats par exemple) pour vérifier les propriétés telles que l'étanchéité et la déformation.
La présente Norme européenne s'appliquant aux joints destinés à être utilisés en ambiances sèche et
humide, tous les joints sont soumis à des essais de fonctionnement en ambiance humide.
La présente Norme européenne ne contient pas toutes les exigences requises pour les conduits de fumée
appartenant aux classes suivantes :
classe 2 de résistance à la corrosion concernant le bois naturel 1) ;
classe 3 de résistance à la corrosion.
La présente Norme européenne est également applicable aux matériaux d'étanchéité, si rien d'autre n'est
défini. Les éprouvettes sont réalisées à partir de matériaux d'étanchéité qui ont été mis sous une forme
pratique et polymérisés conformément aux instructions du fabricant. Les matériaux d'étanchéité polymérisés
satisferont aux mêmes exigences que les joints d'étanchéité.
NOTE Les matériaux d'étanchéité durcis agissent fonctionnellement comme des joints d'étanchéité.
Dimniki - Elastomerna tesnilna sredstva - Zahteve za material in preskusne metode - 1. del: Tesnila v dimničnih tuljavah
Ta evropski standard določa zahteve za material in preskusne metode za predizdelana elastomerna tesnilna sredstva za uporabo v dimničnih tuljavah. Določa tudi zahteve za vrednotenje skladnosti. Ta tesnila so sestavni deli v dimničnih tuljavah različnih materialov, kot so kovina, plastika, glina, beton. Zahteve za delovanje elastomernih tesnil v dimničnih tuljavah so obravnavane v ustreznih standardih za izdelke. V standardih za izdelke so pod obratovalnimi pogoji (npr. temperatura, tlak, mehanska obremenitev, odpadni plin, kondenzat) preskušene ustrezne lastnosti, kot sta puščanje in deformacija, izdelkov, ki sestavljajo dimnike, vključno s tesnili. Ta evropski standard zajema tesnila, namenjena za uporabo v suhih in mokrih razmerah. Zato se delovanje vseh tesnil preskusi v mokrih razmerah.

EN 14241-1:2013 (E) 5 Introduction The objective of this European Standard is to evaluate the material behaviour of prefabricated elastomeric seals for application in flue liners. The testing conditions are representative of normal use, yet severe enough to yield meaningful results in a relatively short period of time. SIST EN 14241-1:2013
EN 14241-1:2013 (E) 6 1 Scope This European Standard specifies the material requirements and test methods for prefabricated elastomeric seals for use in flue liners. It also specifies the requirements for evaluation of conformity. These seals are components in flue liners of different materials such as metal, plastic, clay, concrete. Performance requirements of elastomeric seals in flue liners are covered by the relevant product standards. In the product standards, chimney products, including seals, are tested under operational conditions (e.g. temperature, pressure, mechanical load, flue gas, condensate) to relevant properties such as leakage and deformation. This European Standard covers seals intended for use in both dry and wet conditions. Therefore all seals are tested for functioning under wet conditions. This European Standard does not contain all the requirements necessary for chimneys with the following classification: — corrosion resistance class 2 concerning natural wood1), — corrosion resistance class 3. This European Standard is also applicable for sealants, in case nothing else is defined. The specimens are made from the sealants, which have been brought into a practical form, cured under manufacturers' instructions. The cured sealants will fulfil the same requirements as seals. NOTE Cured sealants are operationally seals in application. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
