ISO 1825:2017规定了四种类型软管和软管组件的尺寸、结构和要求，用于与飞机地面加油和除油相关的所有操作。 这四种类型都是为以下目的设计的: a） 与芳烃含量不超过30%（按体积计）的石油燃料一起使用； b） 在-30°C至+65°C的温度范围内运行，并确保在静态条件下储存时不会受到-40°C至+70°C的气候条件的损坏； c） 在最大工作压力高达2.0 MPa（20 bar）的条件下运行，包括软管在使用中可能承受的压力波动。 注1:C类软管适用于飞机加油用所有车辆的一般压力应用。它们也可用于车辆/轨道车辆装载和排放，不会出现过度真空。 注2:F型软管可用于飞机交付应用，也可用于C型软管不适用的高流速下的卸油。 注3:E型和F型软管也可用于车辆/轨道车的装载和卸载、拖车至燃油器的转移以及升降平台供应（立管），以提供更大的扭结阻力。

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.
