气瓶 - 包含亚气体包装材料（不包括乙炔）的可再填充焊接钢瓶 - 设计 建造 测试 使用和定期检验

[中文适用范围]： 本文件规定了用于低于大气压储存液化和压缩气体的可再充装焊接钢瓶制造过程中的材料、设计、结构、工艺、检查和测试的最低要求。 它仅适用于气瓶本身，而不考虑其中包含的材料（例如吸附剂、介质、材料和/或气体）和其他相关应用。 气瓶的测试压力不大于 42 bar，水容量为 0.5 l 至 12 l，暴露在环境温度下，以便于将液化和压缩气体作为吸附气体进行低于大气压的储存。 还规定了填充时检查以及定期检查和测试的最低要求。 [外文原描述]： This document specifies minimum requirements for the material, design, construction, workmanship, examination and testing at manufacture of refillable welded steel cylinders for the sub-atmospheric pressure storage of liquefied and compressed gases. It only applies to the cylinders themselves, irrespective of the materials contained therein (e.g. adsorbents, media, materials and/or gases) and other related applications. The cylinders have a test pressure not greater than 42 bar and a water capacity from 0,5 l up to and including 12 l exposed to ambient temperatures for the purpose of facilitating the sub‑atmospheric pressure storage of liquefied and compressed gases as adsorbed gases. Minimum requirements for inspection at the time of fill and periodic inspection and testing are also specified.
