AS/NZS ISO 11513:2025
Gas cylinders – Refillable welded steel cylinders containing materials for sub-atmospheric gas packaging (excluding acetylene) – Design, construction, testing, use and periodic inspection
Standard specifies minimum requirements for the material, design, construction, workmanship, examination and testing at manufacture of refillable welded steel cylinders for the sub-atmospheric pressure storage of liquefied and compressed gases.
This document only applies to the cylinders themselves, irrespective of the materials contained therein (e.g. adsorbents, media, materials and gases) and other related applications.
Minimum requirements for inspection at the time of fill and periodic inspection and testing are also specified.
This document is identical with, and has been reproduced from, ISO 11513:2019 Gas cylinders – Refillable welded steel cylinders containing materials for sub-atmospheric gas packaging (excluding acetylene) – Design, construction, testing, use and periodic inspection.
