Hose fittings with screwed ferrules

This European Standard specifies the design, materials and dimensions of hose fittings with screwed ferrules for rubber and thermoplastics hoses for use with flammable and non-flammable liquids or gases, e.g. fuel dispensing hoses, liquid natural gas (LPG) hoses, tank truck hoses and hoses for liquid and chemical chemicals. The nominal sizes covered are DN 13 to DN 40.
Up to DN 25, the maximum working pressure is 25 bar ), and for DN 32 and DN 40 the maximum working pressure is 16 bar.
The working temperature range is -20 °C to +65 °C, for LPG-usage it is -30 °C to +70 °C up to DN 25, and for LT-(low temperature) usage it is -50 °C to +70 °C.

Schlaucharmaturen mit Schraubhülsen

Diese Europäische Norm legt die Ausführung, Werkstoffe und Maße für Schlaucharmaturen mit Schraub-hülsen für Schläuche aus Gummi und Thermoplast für brennbare und nichtbrennbare Flüssigkeiten oder Gase, z. B. Schläuche für Zapfstellen, Schläuche für Flüssiggas (LPG), Schläuche für Tankwagen und Schläuche für flüssige oder gasförmige Chemikalien fest. Sie gilt für die Nennweiten DN 13 bis DN 40.
Bis DN 25 beträgt der höchst zulässige Arbeitsdruck 25 bar ) und für DN 32 und DN 40 beträgt der höchst zulässige Arbeitsdruck 16 bar.
Der Arbeitstemperaturbereich beträgt –20 °C bis 65 °C, für LPG-Anwendungen –30 °C bis 70 °C bis DN 25 und für LT-(Low temperature) Anwendungen –50 °C bis 70 °C.

Raccords pour flexibles avec bague vissée

La présente Norme européenne spécifie les exigences applicables à la conception, aux matériaux et aux dimensions des raccords à bague vissée pour flexibles en caoutchouc et en thermoplastique destinés à être utilisés avec des liquides et des gaz inflammables et ininflammables, comme par exemple les flexibles de distribution de carburant, les flexibles pour gaz naturel liquéfié (GPL), les flexibles de camions citernes et flexibles pour produits chimiques liquides et gazeux. Il couvre les dimensions nominales DN 13 à DN 40.
Jusqu’au DN 25, la pression maximale de service est de 25 bar ), et pour les DN 32 et DN 40 la pression maximale de service est de 16 bar.
La plage de températures de service est de -20 °C à +65 °C, pour utilisations GPL elle est de -30 °C à +70 °C jusqu’au DN 25, et pour utilisations LT (basse température) de -50 °C à +70 °C.

Cevni fitingi z vijačnimi pušami

Ta evropski standard določa načrtovanje, materiale in dimenzije cevnih fitingov z vijačnimi pušami za gumene in plastomerne cevi za uporabo z vnetljivimi ali nevnetljivimi plini, npr. za cevi za točenje goriva, cevi za tekoči zemeljski plin (LPG), cevi za TW cisterne in cevi za tekoče in plinaste kemikalije. Obravnavane nominalne velikosti so od DN 13 do DN 40. Do DN 25 je največji delovni tlak 25 barov1), za DN 32 in DN 40 pa je največji delovni tlak 16 barov. Razpon delovne temperature je od -20 °C do +65 °C, za uporabo za LPG do DN 25 od -30 °C do +70 °C in za uporabo pri nizki temperaturi od -50 °C do +70 °C.
