ISO 11120:1999 Gas cylinders - Refillable seamless steel tubes of water capacity between 150 I and 3 000 I - Design, construction and testing

The International Organization for Standardization (ISO). First edition. 1999-03-15. 40 p. This International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes and tests at manufacture of refillable quenched and tempered seamless steel tubes of water capacities from 150 I up to and including 3 000 I for compressed and liquefied gases exposed to extreme world-wide ambient temperatures (normally between -50 °C and +65 °C). This International Standard is applicable to tubes with a maximum tensile strength Rm of less than 1 100 MPa.
