本文件规定了输送液化石油气和液化天然气的两种热塑性多层（非硫化）输送软管和软管组件的要求。每种类型分为两类，一类用于陆上关税，另一类用于海上关税。 -A类软管用于陆上。 -？B级软管用于海上。 本文件适用于尺寸为25毫米至250毫米的软管，工作压力为10.5巴至25巴，工作温度为196摄氏度至+45摄氏度。 注？海上液化天然气（LNG）软管组件也在EN？1474-2中规定。EN？1474-2不仅规定了海上用途，还规定了船到岸和其他液化天然气输送应用。

This document specifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore. —？Class？A hose is for use onshore. —？Class？B hose is for use offshore. This document is applicable for hose sizes from 25？mm to 250？mm, working pressures from 10,5？bar to 25？bar and operating temperatures from？196？°C to +45？°C, according to class. NOTE？Offshore liquefied natural gas (LNG) hose assemblies are also specified in EN？1474-2. EN？1474-2 does not only specify offshore use, but also ship to shore and other LNG transfer applications.
