This part of ISO 9809 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at manufacture of refillable normalized, or normalized and tempered seamless steel gas cylinders with water capacities from 0,5 | up to and including 150 | for compressed, liquefied and dissolved gases.
NOTE 1 If so desired, cylinders of water capacity less than 0,5 | may be manufactured and certified to this part of ISO 9809.
NOTE 2 For quenched and tempered cylinders with maximum tensile strength less than 1 100 MPa, refer to ISO 9809-1. For quenched and tempered cylinders with maximum tensile strength ≥ 1 100 MPa, refe to ISO 9809-2.
