DIN EN ISO 11120:2010-11

This International Standard specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, examinations and tests at manufacture of refillable quenched and tempered seamless steel tubes of water capacities exceeding 150 l up to and including 3000 l 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 Rma of less than 1100 MPa. These tubes can be used alone or in batteries to equip trailers or multiple element gas containers (ISO modules or skids) for the transportation and distribution of compressed gases. This International Standard does not include requirements relating to any additional stresses that may occur during service or transport, e. g. bending stresses, etc.
