This document 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.
