DIN EN 1968:2005-12

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. 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 3000 l water capacity.
