标准摘要
[中文适用范围]： 本文件为气瓶和阀门的非金属材料与气体含量之间的兼容性的选择和评估提供了指导。 它还适用于管子、压力桶和气瓶束。 本文件涵盖用于气瓶的复合材料和层压材料。 它不包括陶瓷、玻璃和粘合剂。 本文件考虑了气体对改变材料和机械性能（例如化学反应或物理状态的变化）的影响。 不考虑材料的基本属性，例如设计目的所需的机械属性（通常可从材料供应商处获得）。 不考虑其他方面，例如输送气体的质量。 给出的兼容性数据与单一成分气体有关，但也适用于气体混合物。 本文件不适用于低温流体（ISO 21010 中已涵盖）。 [外文原描述]： This document gives guidance on the selection and evaluation of compatibility between non-metallic materials for gas cylinders and valves and the gas contents. It is also applicable to tubes, pressure drums and bundles of cylinders. This document covers composite and laminated materials used for gas cylinders. It does not include ceramics, glasses and adhesives. This document considers the influence of the gas in changing the material and mechanical properties (e.g. chemical reaction or change in physical state). The basic properties of the materials, such as mechanical properties required for design purposes (normally available from the materials supplier), are not considered. Other aspects, such as quality of delivered gas, are not considered. The compatibility data given are related to single component gases but can be applicable to gas mixtures. This document does not apply to cryogenic fluids (this is covered in ISO 21010).
