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).

<p> La présente norme donne des lignes directrices pour la sélection et l'évaluation de la compatibilité entre les matériaux non métalliques des bouteilles à gaz/robinets avec le contenu gazeux des bouteilles. La présente norme couvre également les cadres, tubes et fûts sous pression. La présente norme peut se révéler utile pour les matériaux composites et les matériaux stratifiés. Seule l'influence du gaz sur la transformation du matériau ou sur la modification de ses propriétés mécaniques est considérée (par exemple une réaction chimique ou une modification de l'état physique). Les propriétés mécaniques fondamentales des matériaux requises pour la conception d'un produit sont en général fournies par le fabricant du matériau et ne sont donc pas abordées dans cette norme. Les données de compatibilité indiquées se rapportent à des gaz à un composant unique mais elles peuvent être utilisées dans une certaine mesure pour des mélanges gazeux. Les céramiques, les verres et les adhésifs ne sont pas traités dans cette norme. D'autres aspects, tels que la qualité du gaz fourni, ne sont pas pris en compte. </p>
