(Main)Rubber materials for seals and diaphragms for gas appliances and gas equipment
Rubber materials for seals and diaphragms for gas appliances and gas equipment
This standard specifies requirements and associated test methods for rubber materials used in gas installations, gas equipment and gas appliances in contact with 1st, 2nd and 3rd family combustible gases as classified in EN 437 e.g. natural gas, LPG, bio methane bio LPG. It also establishes a classification based on temperature range and hardness. This standard is applicable to materials from which are manufactured homogeneous seals and homogeneous or reinforced diaphragms.
Since the dimensions and shape of the components differ from those of standard test pieces taken from sheet material as used for type testing of the rubber materials according to this standard, tolerances have been made in the requirements specified by Annex A for the components with respect to those specified for standard test pieces.
The range of operating temperatures covered by this standard is - 40 °C to + 150 °C.
This standard is not applicable for silicone rubber used either above 200 hPa (200 mbar) nominal pressure or at temperatures below 0 °C with 3rd family gases, as there is the possibility of condensation.
Elastomer-Werkstoffe für Dichtungen und Membranen in Gasgeräten und Gasanlagen
Diese Norm legt Anforderungen und zugehörige Prüfverfahren für Elastomer-Werkstoffe fest, die in Gasgeräte und Gasanlagen in Kontakt mit Brenngasen der 1., 2. und 3. Gasfamilie, wie in EN 437 klassifiziert z. B. Erdgas, Flüssiggas, Bio-Erdgas und Bio-Flüssiggas, eingesetzt werden. Sie stellt außerdem eine Klassifizierung nach Temperaturbereich und Härte auf. Diese Norm gilt für Werkstoffe, aus denen homogene Dichtungen und homogene oder verstärkte Membranen hergestellt werden.
Da die Abmessungen und die Form der Fertigteile von denen genormter Probekörper, hergestellt aus Plattenmaterial, wie sie zur Typprüfung von Elastomer-Werkstoffen nach dieser Norm verwendet werden, abweichen, wurden größere Toleranzen in den für Fertigteile in Anhang A festgelegten Anforderungen gegenüber den für Normprobekörper festgelegten Anforderungen eingeräumt.
Der Bereich der Betriebstemperaturen, der von dieser Norm abgedeckt wird, reicht von − 40 °C bis + 150 °C.
Diese Norm gilt weder für den Einsatz von Silikongummi bei Nenndruck über 200 hPa (200 mbar) noch bei Temperaturen unter 0 °C in Kontakt mit Gasen der 3. Gasfamilie, da unter diesen Umständen Kondensation möglich ist.
Matériaux à base de caoutchouc pour joints d'étanchéité et membranes destinés aux appareils à gaz et appareillages pour le gaz
La présente norme définit les exigences et les méthodes d'essai associées relatives aux matériaux en caoutchouc utilisés dans les installations, appareils d'utilisation et équipement de gaz en contact avec les combustibles gazeux de première, deuxième ou troisième famille selon la classification de l'EN 437, par exemple, gaz naturel, GPL, biométhane, bio GPL. Elle établit également une classification basée sur une gamme de températures et de duretés. La présente norme est applicable aux matériaux à partir desquels sont fabriqués les joints d’étanchéité homogènes et les membranes homogènes ou renforcées.
Étant donné que les dimensions et la forme des pièces diffèrent de celles des éprouvettes normalisées prélevées dans des plaques du matériau et utilisées pour les essais de type des matériaux en caoutchouc au sens de la présente norme, des tolérances ont été apportées aux exigences spécifiées pour les pièces, à l'Annexe A, par rapport à celles spécifiées pour les éprouvettes normalisées.
La gamme de températures de service couverte par la présente norme est de - 40 °C à + 150 °C.
La présente norme n'est pas applicable au caoutchouc silicone utilisé au-dessus d'une pression nominale de 200 hPa (200 mbar) ou à des températures inférieures à 0 °C avec la troisième famille de gaz, car il y a possibilité de condensation.
Gumeni materiali za tesnila in membrane v plinskih aparatih in plinskih napravah
Ta standard določa zahteve in z njimi povezane preskusne metode za gumene materiale, ki se uporabljajo v plinskih napravah, plinski opremi in plinskih aparatih v stiku z vnetljivimi plini razredov 1, 2 in 3, razvrščenimi v skladu s standardom EN 437, npr. zemeljski plin, utekočinjeni naftni plin, bioplin, bio-metan. Vzpostavlja tudi razvrstitev glede na temperaturno območje delovanja in trdoto. Ta standard se uporablja za materiale, iz katerih so izdelana homogena tesnila in homogene ali ojačane membrane.
Ker se mere in oblika komponent razlikujejo od standardnih preskušancev iz plastnega materiala, ki se uporabljajo za preskušanje tipa gumenih materialov v skladu s tem standardom, so bila v delih, določenih v dodatku A, določena dovoljena odstopanja za komponente glede na tiste, ki veljajo za standardne preskušance.
Temperaturno območje delovanja, ki ga zajema ta standard, je od –40 do 150 °C.
Ta standard se ne uporablja za silikonsko gumo, ki se uporablja bodisi pri nominalnem tlaku nad 200 hPa (200 mbar) bodisi pri temperaturah pod 0 °C s plini razreda 3, saj obstaja možnost kondenzacije.
