This document 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. For LT hose, the temperature range of -40 °C to +65 °C and such that they will be undamaged by climatic conditions of -48 °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
