标准范围

本文件规定了体积大于450 l的大型可运输真空绝热低温容器的设计、制造、检查和测试要求，这些容器永久（固定罐）或非永久（可拆卸罐和移动罐）连接到运输工具上，用于一种或多种运输方式。本文件适用于3.1中规定流体的大型可运输真空绝热低温容器，不适用于设计用于有毒流体的容器。本文件不包括车辆的一般要求，例如传动装置、制动器、照明等。注1:本文件不包括主要用作车辆燃料箱的可再充装液氢罐的具体要求。陆上车辆使用的燃油箱见ISO 13985。注2:本文件不包括主要用作车辆燃料箱的可再充装液态氢和液化天然气储罐的具体要求。有关车辆中使用的燃油箱，请参见ISO 13985。

This document specifies requirements for the design, fabrication, inspection and testing of large transportable vacuum-insulated cryogenic vessels of more than 450 l volume, which are permanently (fixed tanks) or not permanently (demountable tanks and portable tanks) attached to a means of transport, for one or more modes of transport.This document applies to large transportable vacuum-insulated cryogenic vessels for fluids specified in 3.1 and does not apply to vessels designed for toxic fluids.This document does not include the general vehicle requirements, e.g. running gear, brakes, lighting, etc.NOTE 1 This document does not cover specific requirements for refillable liquid-hydrogen tanks that are primarily dedicated as fuel tanks in vehicles. For fuel tanks used in land vehicles, see ISO 13985.NOTE 2 This document does not cover specific requirements for refillable liquid hydrogen and LNG tanks that are primarily dedicated as fuel tanks in vehicles. For fuel tanks used in vehicles, see ISO 13985.
