This European Standard specifies the dimensions, construction and requirements for four types of hoses and hose assemblies for use in all operations associated with the ground fuelling and de fuelling of aircraft.
All four types of hose 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 are to be undamaged by climatic conditions of -40 °C to +70 °C when stored in static conditions;
c) operating up to 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 application on all vehicles used for into - plane fuelling. It 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 into-plane delivery applications on vehicles that are also used for de-fuelling at high flow rates, where Type C hoses are not suitable.
NOTE 3 Types E & 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.
