Gas cylinders - Design, construction and testing of refillable seamless steel gas cylinders and tubes - Part 4: Stainless steel cylinders with an R m value of less than 1 100 MPa (ISO/DIS 9809-4:2024)

This document specifies the minimum requirements for the materials, design, construction and workmanship, manufacturing processes, examinations and testing at time of manufacture for refillable, seamless, stainless steel gas cylinders with water capacities up to and including 150 l.
It is applicable to cylinders for compressed, liquefied and dissolved gases with a maximum actual tensile strength, Rma, of less than 1 100 MPa.
NOTE         If so desired, cylinders of water capacity between 150 l and 450 l can be manufactured to be in full conformance to this document.

Gasflaschen - Auslegung, Herstellung und Prüfung von wiederbefüllbaren nahtlosen Gasflaschen aus Stahl - Teil 4: Flaschen aus Edelstahl mit einem Rm-Wert von weniger als 1 100 MPa (ISO/DIS 9809‑4:2024)

Bouteilles à gaz - Conception, construction et essais des bouteilles à gaz et des tubes rechargeables en acier sans soudure - Partie 4: Bouteilles en acier inoxydable ayant une valeur de Rm inférieure à 1 100 MPa (ISO/DIS 9809-4:2024)

Le présent document spécifie les exigences minimales concernant le matériau, la conception, la construction et la mise en œuvre, les procédés de fabrication, les examens et les essais au moment de la fabrication des bouteilles à gaz rechargeables en acier sans soudure d’une contenance en eau inférieure ou égale à 150 l.
Il s’applique aux bouteilles pour les gaz comprimés, liquéfiés et dissous ayant une résistance à la traction réelle, Rma, maximale inférieure à 1 100 MPa.
NOTE            Si cela est souhaité, les bouteilles d’une contenance en eau comprise entre 150 l et 450 l peuvent être fabriquées conformément au présent document.
