标准范围

ISO 11114-2:2013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。它还包括管束、管道和压力桶。ISO 11114-2:2013有助于气瓶用复合材料和层压材料。本指南并未完全涵盖该主题，仅在评估气体/材料组合的相容性时提供指导。仅考虑气体对材料和机械性能的影响（例如化学反应或物理状态的变化）。设计所需的材料基本性能，如机械性能，通常可从材料供应商处获得，不予以考虑。给出的相容性数据与单组分气体有关，但在一定程度上可用于气体混合物。陶瓷、玻璃和粘合剂不包括在内。未考虑输送气体的质量等其他方面。ISO 11114-2:2013不适用于低温流体（见ISO 21010）。

ISO 11114-2:2013 gives guidance in the selection and evaluation of compatibility between non-metallic materials for gas cylinders and valves and the gas contents. It also covers bundles, tubes and pressure drums.ISO 11114-2:2013 can be helpful for composite and laminated materials used for gas cylinders.It does not cover the subject completely and is intended to give guidance only in evaluating the compatibility of gas/material combinations.Only the influence of the gas in changing the material and mechanical properties is considered (for example chemical reaction or change in physical state). The basic properties of the materials, such as mechanical properties, required for design purposes are normally available from the materials' supplier and are not considered.The compatibility data given are related to single component gases but can be used to some extent for gas mixtures. Ceramics, glasses, and adhesives are not covered.Other aspects such as quality of delivered gas are not considered.ISO 11114-2:2013 is not intended to be used for cryogenic fluids (see ISO 21010).
