Rubber and plastic hoses and hose assemblies for measured fuel dispensing systems - Specification

This European Standard specifies minimum requirements and test methods for verification for three types of hoses in two grades and two classes of hose assemblies used for measured fuel dispensing, including oxygenated fuels (up to a maximum of 15 % oxygenated compounds).
The assemblies are intended for use at ambient temperatures between –30 °C and +55 °C for normal temperature class and –40 °C and +55 °C for low temperature class at a working pressure  16 bar ).
As part of the certification of a new dispenser, testing of fuel samples in accordance with EN 228 and EN 590 should be carried out at least eight weeks after the first use of the equipment to avoid unrepresentative sulphur content results.

Zapfstellenschläuche und -schlauchleitungen aus Gummi und Kunststoff - Anforderungen

Diese Europäische Norm legt die Mindestanforderungen für drei Typen von Zapfstellenschläuchen für Kraft-stoffe fest, die in zwei Kategorien und zwei Klassen unterteilt werden, wobei mit sauerstoffhaltigen Verbin-dungen angereicherte Kraftstoffe (bis zu einem maximalen Anteil von 15 % sauerstoffhaltigen Verbindungen) einbezogen sind.
Die Anwendung von Schlauchleitungen der Normaltemperaturklasse ist bei Umgebungstemperaturen von 30 °C bis 55 °C und von Schlauchleitungen der Tieftemperaturklasse zwischen -40 °C und +55 °C bei einem Arbeitsdruck von  16 bar ) vorgesehen.
Als Teil der Zertifizierung einer neuen Zapfsäule sollten Kraftstoffproben nach EN 228 und EN 590 mindestens acht Wochen nach der ersten Verwendung der Ausrüstung geprüft werden, um unrepräsentative Ergebnisse in Zusammen¬hang mit dem Schwefelgehalt zu vermeiden.

Tuyaux et flexibles en caoutchouc et en plastique pour distribution mesurée de carburant - Spécifications

La présente Norme européenne spécifie les exigences minimales et les méthodes d’essai pour la vérification de trois types de tuyaux dans deux catégories et deux classes d’assemblages flexibles utilisés pour la distribution mesurée des carburants, y compris les carburants oxygénés (comprenant jusqu’à 15 % maximum de mélanges oxygénés).
Les assemblages sont destinés à être utilisés à des températures ambiantes comprises entre  30 °C et  55 °C pour une classe de température normale et entre  40 °C et  55 °C pour la classe basse température à une pression en service  16 bar ).
Dans le cadre de la certification d’un nouveau distributeur, il convient qu’un essai d’échantillons de carburant conformément à l’EN 228 et à l’EN 590 soit réalisé au moins huit semaines après la première utilisation de l'équipement afin d'éviter des résultats en teneur en soufre peu représentatifs.

Gumene in polimerne cevi ter cevni priključki za sisteme za merjeno točenje goriv - Specifikacija

Ta evropski standard določa minimalne zahteve za tri vrste cevi v dveh kategorijah in dva razreda cevnih priključkov za sisteme za merjeno točenje goriva, vključno z oksigeniranimi gorivi (do največ 15 % kisikovih spojin).

EN 1360:2013 (E) 6 4 Classification Hoses for this application shall be divided into three types:  Type 1: textile reinforced;  Type 2: textile and helical wire reinforced;

 Type 3: fine wire reinforced. Each type of hose shall be divided into two grades:  Grade M: electrically bonded;  Grade Ω: electrically conductive. Each type of hose shall be divided into two temperature classes:  Normal temperature class with an ambient working temperature of −30 °C to +55 °C;  Low temperature class (LT) with an ambient working temperature of −40 °C to +55 °C. 5 Materials and construction The hose shall consist of the following: a) a smooth, fuel resistant lining of rubber or thermoplastic elastomer (TPE); b) a reinforcement; related to type; c) a non-corrugated, fuel and weather-resistant rubber or TPE cover. Hose assemblies shall be capable of conducting an electrical charge from coupling to coupling. When this capability is provided by means of metallic bonding wires, not less than two (metallic) bonding wires shall be embedded in the hose and the metal used shall have a high resistance to fatigue and corrosion. Hoses with metallic wires for electrical conductivity shall be designated 'M' and those using conductive compounds shall be designated 'Ω', the relevant mark being branded on the hose (see Clause 12). 6 Pressure requirements For all types of hoses the following shall apply: a) maximum working pressure: 16 bar; b) proof pressure: 24 bar; c) minimum bursting pressure: 48 bar. 7 Dimensions and tolerances 7.1 Internal diameters and bend radii When measured in accordance with EN ISO 4671, the internal diameter of the hose shall comply with the values given in Table 1. SIST EN 1360:2013

EN 1360:2013 (E) 7 When measured in accordance with EN ISO 10619-1, the minimum bend radii for each diameter of hose shall be in accordance with Table 1.

7.2 Minimum thickness of lining and cover When measured in accordance with EN ISO 4671, the thickness of the lining shall not be less than 1,6 mm. The thickness of the cover shall not be less than 1,0 mm. 7.3 Concentricity When determined in accordance with EN ISO 4671, the concentricity, based on a total indicator reading between the internal diameter and the outside surface of the cover, shall not exceed 1,0 mm.

7.4 Tolerance on cut lengths For cut lengths, the tolerances on length shall be in accordance with EN ISO 1307. The length of a hose assembly shall be measured from sealing face to sealing face of the end fittings with a tolerance from the nominal length of ± 1%. 8 Physical properties 8.1 Compounds When tested in accordance with the methods specified in Table 2, the physical properties of the compounds used for the lining and cover shall comply with the values specified in Table 2. Tests shall be performed either on samples taken from the hose or from moulded vulcanised sheets at a thickness of 2 mm or moulded test pieces, vulcanised to the same cured state as the production hoses.
