This European Standard specifies the requirements for periodic inspection and testing of
seamless steel transportable gas cylinders (single or those from bundles) intended for
compressed and liquefied gases under pressure, of water capacity from 0,5 l up to 150 l.
NOTE As far as practicable, this standard may also be applied to cylinders of less than 0,5 l water
capacity and for tubes up to 3 000 l water capacity.
