本文件给出了气瓶和阀门用非金属材料与气体含量之间兼容性的选择和评估指南。它也适用于管道、压力桶和钢瓶束。 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材料和机械性能（例如化学反应或物理状态变化）的影响。不考虑材料的基本性能，例如设计所需的机械性能（通常可从材料供应商处获得）。其他方面，如输送气体的质量，则不予考虑。 给出的相容性数据与单组分气体有关，但可适用于气体混合物。 本文件不适用于低温流体（ISO 21010中有相关规定）。

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).
