本文件规定了定期检查和测试0.5L至150L水容量的焊接铝合金、碳和不锈钢气瓶的要求，这些气瓶用于压力下的压缩和液化气体服务，并验证这些气瓶的完整性，以便进一步服务。它也适用于水容量小于0.5L且大于150L至450L的钢瓶。本文件不适用于乙炔钢瓶或复合（全包装或环包装）钢瓶的定期检查和试验。它主要用于装有液化石油气（LPG）以外的工业气体的钢瓶。本文件也适用于液化石油气。ISO 10464中也提供了液化石油气应用的要求。

This document specifies the requirements for the periodic inspection and testing of welded aluminium-alloy, carbon and stainless steel gas cylinders of water capacity from 0,5 l to 150 l intended for compressed and liquefied gas service under pressure and to verify the integrity of such gas cylinders for further service. It also applies, as far as is practical, to cylinders of less than 0,5 l water capacity and greater than 150 l up to 450 l. This document does not apply to the periodic inspection and testing of acetylene cylinders or composite (fully wrapped or hoop-wrapped) cylinders. It is primarily intended for use with cylinders containing industrial gases other than liquefied petroleum gas (LPG). This document may also be applicable to LPG. Requirements for LPG applications are also provided in ISO 10464.
