本文件规定了定期检查和测试的要求，以验证带铝合金、钢或非金属衬里或无衬里结构（2、3、4和5类）的环箍包裹和全包裹复合材料可运输气瓶和管道的完整性，用于在压力下压缩、液化或溶解气体，水容量从0.5升到3000升。 本文件涉及根据ISO 11119-1、ISO 11119-2、ISO 11119-3、ISO 1119-4或ISO 11515制造的复合材料圆柱体和管道的定期检查和测试。经主管当局授权，它可以应用于其他按照类似标准设计的复合材料圆柱体和管道。在可行的范围内，经制造商授权，本文件也可适用于水容量小于0.5升的气瓶。 注意除非另有说明，否则本文件中使用的“圆柱体”一词同时指圆柱体和管道。

This document specifies the requirements for periodic inspection and testing to verify the integrity for further service of hoop-wrapped and fully-wrapped composite transportable gas cylinders and tubes, with aluminium-alloy, steel or non-metallic liners or of linerless construction (Types 2, 3, 4, and 5), intended for compressed, liquefied or dissolved gases under pressure, of water capacity from 0,5 l up to 3 000 l. This document addresses the periodic inspection and testing of composite cylinders and tubes constructed according to ISO 11119-1, ISO 11119-2, ISO 11119-3, ISO 11119-4 or ISO 11515. It can be applied to other composite cylinders and tubes designed to comparable standards when authorized by the competent authority. As far as practicable, this document can also be applied to cylinders of less than 0,5 l water capacity when authorized by the manufacturer. NOTE？Unless noted by exception, the use of the word “cylinder” in this document refers to both cylinders and tubes.
