ISO 9809-3:2010
Gas cylinders — Refillable seamless steel gas cylinders — Design, construction and testing — Part 3: Normalized steel cylinders
ISO 9809-3:2010 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examination and testing at manufacture of refillable normalized or normalized and tempered seamless steel gas cylinders of water capacities from 0,5 l up to and including 150 l for compressed, liquefied and dissolved gases.
If desired, cylinders of water capacity less than 0,5 l can be manufactured and certified to be in compliance with ISO 9809-3:2010.
