标准范围

This document specifies minimum requirements for the material, design, construction and 
workmanship, manufacturing processes, examination and testing at time of manufacture for refillable 
seamless steel gas cylinders and tubes with water capacities up to and including 450 l. 
it is applicable to cylinders and tubes for compressed, liquefied and dissolved gases and for quenched 
and tempered steel cylinders and tubes with an actual tensile strength R_ma ≥ 1 100 MPa.
It is not applicable to cylinders and tubes with R_{ma, max} > 1 300 MPa for diameters >140 mm and 
guaranteed wall thicknesses a′ ≥ 12 mm and for cylinders and tubes with R_{ma, max}  > 1 400 MPa for 
diameters ≤140 mm and guaranteed wall thicknesses a′ ≥ 6 mm because, beyond these limits, additional 
requirements can apply.
