Tanks for the transport of dangerous goods - Tank equipment for the transport of liquid chemicals and liquefied gases - Product discharge and air inlet valves

This European Standard specifies the requirements for product discharge and air inlet valves for use on transportable tanks with a minimum working pressure greater than 50 kPa for the transport of dangerous goods by road and rail.
NOTE 1   The term 'valve' includes ball valves as well as butterfly valves and similar closure devices.
It is applicable to metallic equipment for use on tanks with gravity and/or pressure filling and discharge for liquid chemicals and liquefied gases. It includes carbon dioxide while excluding refrigerated liquefied gases.
NOTE 2   The standard is also applicable to liquefied gases including LPG, however, for a dedicated LPG standard see EN 13175 [3].

Tanks für die Beförderung gefährlicher Güter - Ausrüstung für Tanks für die Beförderung von flüssigen Chemieprodukten und Flüssiggasen - Produktabsperr- und Gaswechselventile

Diese Europäische Norm legt die Anforderungen an Produktabsperr- und Gaswechselventile für die Verwen¬dung an ortsbeweglichen Tanks mit einem Mindest-Betriebsdruck von mehr als 50 kPa für die Beförderung gefährlicher Güter auf der Straße und auf der Schiene fest.
ANMERKUNG 1   Der Begriff „Ventil“ schließt sowohl Kugelhähne als auch Absperrklappen sowie vergleichbare Schließeinrichtungen ein.
Sie gilt für Ausrüstung aus Metall für Tanks für flüssige Chemieprodukte und Flüssiggase, die mittels Schwerkraft und/oder Druck entleert werden. Dies schließt Kohlendioxid ein und tiefkalte Gase aus.
ANMERKUNG 2   Die Norm gilt ebenfalls für verflüssigte Gase, einschließlich Flüssiggas (LPG); für eine einschlägige Flüssiggasnorm wird auf EN 13175 [3] verwiesen.

Citernes de transport de matières dangereuses - Équipements de la citerne pour le transport de produits chimiques liquides et de gaz liquéfiés - Vannes de mise en pression de la citerne ou de déchargement du produit

La présente Norme européenne spécifie les exigences relatives aux vannes de mise en pression et de déchargement du produit sur les citernes transportables, dont la pression minimale de service est supérieure à 50 kPa, pour le transport routier ou ferroviaire des matières dangereuses.
NOTE 1   Le terme « vanne » inclut les robinets à tournant sphérique et les vannes papillon et autres dispositifs d’obturation similaires.
Elle est applicable aux équipements métalliques utilisés sur les citernes à remplissage et à déchargement par gravité et/ou sous pression pour produits chimiques liquides et gaz liquéfiés. Elle inclut le dioxyde de carbone, mais exclut les gaz liquéfiés réfrigérés.
NOTE 2   La norme s’applique également aux gaz liquéfiés, y compris le GPL. Toutefois, pour une norme spécifique au GPL, se reporter à l’EN 13175 [3].

Cisterne za prevoz nevarnega blaga - Oprema posode za prevoz tekočih kemikalij in utekočinjenih plinov - Izpustni ventili in ventili za vstop plina pri praznjenju

Ta evropski standard določa zahteve za vakuumske oddušnike in ventile za vstop zraka za uporabo pri premičnih cisternah z najnižjim delovnim tlakom nad 50 kPa za cestni in železniški prevoz nevarnega blaga.
Uporablja se za opremo za uporabo pri cisternah s težnostnim in/ali tlačnim praznjenjem za tekoče kemikalije ter utekočinjene pline. Vključuje ogljikov dioksid, ne zajema pa kriogenskih plinov.
