BS EN ISO 9809-2:2010 Gas cylinders. Refillable seamless steel gas cylinders. Design, construction and testing. Quenched and tempered steel cylinders with tensile strength greater than or equal to 1100 MPa
BS EN ISO 9809-2 specifies minimum requirements for refillable quenched 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.
It covers:
Materials
Design
Construction and workmanship
Manufacturing processes
Examination and testing at manufacture
BS EN ISO 9809-2 is applicable to cylinders with a maximum tensile strength Rma W 1 100 MPa. It is not applicable to cylinders with Rma, max > 1 300 MPa for diameters > 140 mm and guaranteed wall thicknesses a′ W 12 mm and Rma, max > 1 400 MPa for diameters u 140 mm and guaranteed wall thicknesses a′ W 6 mm, because beyond these limits, additional requirements can apply.
