标准摘要
[中文适用范围]： 涵盖了从软管本身到各类组件的完整系统，涉及耐压能力、耐化学介质性能、柔韧性以及标识标识等关键要素。通过统一技术规格，该文件为相关产品的研发、生产、检验及验收提供了明确依据，有助于提升航空地面保障作业的整体水平，减少因设备质量问题引发的潜在风险，促进相关领域内技术的一致性与互换性。 [外文原描述]： 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: use with petroleum fuels having an aromatic-hydrocarbon content not exceeding 30 % by volume; 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; 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.
