Small craft - Fire-resistant fuel hoses (ISO 7840:2021)
This document specifies general requirements and physical tests for fire-resistant hoses for conveying petrol or petrol blended with ethanol, and diesel fuel or diesel fuel blended with FAME, designed for a working pressure not exceeding 0,34 MPa for hoses with inner diameter up to and including 10 mm, and 0,25 MPa for hoses up to 63 mm inner diameter in small craft.
It applies to hoses for small craft with permanently installed fuel systems. It does not apply to hoses entirely within the splash well at the stern of the craft connected directly to an outboard engine.
Specifications for non-fire-resistant fuel hoses are given in ISO 8469:2021. Specifications for permanently installed fuel systems are given in ISO 10088:2013.
Kleine Wasserfahrzeuge - Feuerwiderstandsfähige Kraftstoffschläuche (ISO 7840:2021)
Dieses Dokument spezifiziert allgemeine Anforderungen und physikalischen Prüfungen für feuerwiderstandsfähige Schläuche für kleine Wasserfahrzeuge, durch die Benzin oder ein Benzin Ethanol Gemisch oder Diesel oder ein Diesel FAME Gemisch geleitet wird, die für Betriebsüberdrücke bis höchstens 0,34 MPa bei Schläuchen mit Innendurchmesser bis einschließlich 10 mm ausgelegt sind und mit Betriebsüberdrücken bis höchstens 0,25 MPa bei Schläuchen mit Innendurchmesser bis 63 mm ausgelegt sind.
Es gilt für Schläuche auf kleinen Wasserfahrzeugen mit fest eingebauten Kraftstoffsystemen. Es gilt nicht für Schläuche, die vollständig innerhalb des Spritzschutzes am Heck des Fahrzeugs liegen und direkt mit einem Außenbordmotor verbunden sind.
Festlegungen für nicht feuerwiderstandfähige Kraftstoffschläuche sind in ISO 8469:2021 angegeben. Festlegungen für fest eingebaute Kraftstoffsysteme sind in ISO 10088:2013 enthalten.
Petits navires - Tuyaux souples pour carburant résistants au feu (ISO 7840:2021)
Le présent document spécifie les exigences générales et les essais physiques relatifs aux tuyaux souples résistants au feu pour le transport d'essence ou d'essence mélangée avec de l'éthanol et de carburant diesel ou de carburant diesel mélangé avec des FAME/EMAG, conçus pour une pression de service n'excédant pas 0,34 MPa pour les tuyaux souples de diamètre intérieur égal ou inférieur à 10 mm, et 0,25 MPa pour les tuyaux souples de diamètre intérieur allant jusqu'à 63 mm, installés sur les petits navires.
Il s'applique aux tuyaux souples destinés aux petits navires dont le système à carburant est installé à demeure. Il ne s'applique pas aux tuyaux entièrement situés à l'intérieur du puits de moteur hors bord situé à l'arrière du bateau et directement reliés à un moteur hors-bord.
Les spécifications pour les tuyaux non-résistant au feu sont données dans l'ISO 8469:2021. Les spécifications pour les systèmes de carburant installés à demeure sont données dans l'ISO 10088:2013.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
