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.

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).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

This document was prepared by Technical Committee ISO/TC 188, Small craft, in collaboration with

the European Committee for Standardization (CEN) Technical Committee CEN/TC 464, Small craft, in

accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This fifth edition cancels and replaces the fourth edition (ISO 7840:2013), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— requirements for low permeation fuel hoses have been added in 6.9;
— the test fluids in 6.2 for petrol have been clarified;

— the test set-up in Figure B.1 has been revised to remove the vented capillary tube.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.
