RS ISO 11114-2
Gas cylinders — Compatibility of cylinder and valve materials with gas contents — Part 2: Non-metallic materials

Abstract

This part of ISO 11114 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.
This part of ISO 11114 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 in this part of ISO 11114.
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 by this part of ISO 11114.
Other aspects such as quality of delivered gas are not considered.
This part of ISO 11114 is not intended to be used for cryogenic fluids (see ISO 21010)
