Rubber hoses and hose assemblies for aircraft ground fuelling and defuelling - Specification (ISO/DIS 1825:2025)

ISO 1825:2017 specifies the dimensions and construction of, and requirements for, four types of hose and hose assembly for use in all operations associated with the ground fuelling and defuelling of aircraft.
All four types are designed for:
a) use with petroleum fuels having an aromatic-hydrocarbon content not exceeding 30 % by volume;
b) operation within the temperature range of −30 °C to +65 °C and such that they will be undamaged by climatic conditions of −40 °C to +70 °C when stored in static conditions;
c) operation at up to 2,0 MPa (20 bar) maximum working pressure, including surges of pressure which the hose can be subjected to in service.
NOTE 1 Type C hoses are intended for general pressure applications on all vehicles used for plane fuelling. They can also be used for vehicle/rail car loading and discharge where excessive vacuum does not occur.
NOTE 2 Type F hoses can be used for plane delivery applications on vehicles that are also used for defuelling at high flow rates where type C hoses are not suitable.
NOTE 3 Type E and F hoses can also be used for vehicle/rail car loading and discharge, for trailer to fueller transfer and for elevation platform supply (riser) to provide greater kink resistance.

Tuyaux et flexibles en caoutchouc pour le ravitaillement carburant et la vidange des avions au sol - Spécifications (ISO/DIS 1825:2025)

ISO 1825:2017 spécifie les dimensions, et la construction de, et les exigences pour, quatre types de tuyaux et de flexibles destinés à être utilisés pour toutes les opérations de ravitaillement et de déchargement de carburant des avions au sol.
Les quatre types sont conçus pour:
a) être utilisés avec des carburants à base de pétrole dont la teneur en hydrocarbures aromatiques ne dépasse pas 30 % en volume;
b) fonctionner dans une plage de température de ?30 °C à +65 °C et être ne pas être endommagés dans des conditions climatiques de ?40 °C à +70 °C lorsqu'ils sont stockés en condition statique;
c) fonctionner jusqu'à une pression maximale de service de 2,0 MPa (20 bar), y compris les surpressions subies en service.
NOTE 1 Les tuyaux de type C sont destinés aux applications générales pour tout véhicule utilisé pour le ravitaillement en carburant des avions. Ils peuvent aussi être utilisés pour le remplissage et le déchargement de citerne/wagon lorsqu'il n'y a pas de vide excessif.
NOTE 2 Les tuyaux de type F peuvent être utilisés pour la livraison de carburant aux avions sur des véhicules utilisés aussi pour le déchargement à haut débit lorsque les types C ne conviennent pas.
NOTE 3 Les tuyaux de type E et F peuvent aussi être utilisés pour le remplissage et le déchargement de citerne/wagon, pour les remorques à transfert de carburant et pour les plates formes élévatrices afin d'avoir une meilleure résistance au coquage.

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).
