本文件规定了定期检查和测试的要求，以验证在未来一段时间内重新投入使用的气瓶和管道的完整性。 本文件适用于在压力下用于压缩和液化气体的无缝钢和无缝铝合金可运输气瓶（单个或由一捆组成的），水容量从0.5升到150升，以及水容量大于150升的无缝钢和无缝铝合金可运输气管（单根或由一束组成的），用于在压力下压缩和液化气体。 在实际情况下，它也适用于水容量小于0.5升的钢瓶。包含以下内容:BS EN ISO 18119:2018

This document specifies the requirements for periodic inspection and testing to verify the integrity of cylinders and tubes to be re-introduced into service for a further period of time. This document is applicable to seamless steel and seamless aluminium-alloy transportable gas cylinders (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l and to seamless steel and seamless aluminium-alloy transportable gas tubes (single or those that comprise a bundle) intended for compressed and liquefied gases under pressure, of water capacity greater than 150 l. It also applies, as far as practical, to cylinders of less than 0,5 l water capacity.Incorporates the following:BS EN ISO 18119:2018
