Description / 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).
