ISO 9809-2:2000 PDF

Scope: This part of ISO 9809 specifies minimum requirements for the material, design, construction and workmanship, manufacturing processes, and tests at manufacture of refillable quenched and tempered seamless steel gas cylinders of water capacities from 0,5 | up to and including 150 | for compressed, liquefied and dissolved gases exposed to extreme world wide ambient temperatures (normally between - 50 ℃ and + 65 ℃). This part of ISO 9809 is applicable to cylinders with a maximum tensile strength Rm of greater than or equal to 1 100 MPa. It does not cover cylinders with Rmmax. > 1 300 MPa for diameters > 140 mm and guaranteed wall thicknesses (a') ≥ 12 mm, and Rmmax. ≥ 1 400 MPa for diameters ≤140 mm and guaranteed wall thicknesses (a') ≥ 6 mm, because beyond these limits additional requirements may apply. 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 normalized steel cylinders refer to ISO 9809-3. NOTE 3 Grades and strength ranges of steels used for these types of cylinders may not be compatible with some gas services (see 6.1.4) and operational conditions.
