La présente norme européenne spécifie les exigences minimales relatives aux matériaux, au calcul, à la procédure de construction et d'exécution, et aux essais en usine des réservoirs cylindriques fixes en acier soudés, de série, destinés au stockage de GPL, présentant un volume inférieur ou égal à 13m cube destinés à une installation aérienne. La gamme normalisée s'appuie sur des réservoirs cylindriques à fonds semi-elliptiques et torisphériques. Un grand nombre de diamètres et d'épaisseur normalisés sont spécifiés en utilisant des nuances de matériaux sélectionnés dans les parties 2 et 3 de l'EN 10028.
