Describes requirements for the design, fabrication, inspection and testing of static vacuum-insulated cryogenic vessels designed for a maximum allowable pressure of more than 0,5 bar.

This part of ISO21009 specifies requirements for the design, fabrication, inspection and testing of static vacuum-insulated cryogenic vessels designed for a maximum allowable pressure of more than 0,5 bar.

This part of ISO21009 applies to static vacuum-insulated cryogenic vessels for fluids as specified in 3.4 and does not apply to vessels designed for toxic fluids.

For static vacuum-insulated cryogenic vessels designed for a maximum allowable pressure of not more than 0,5 bar this International Standard may be used as a guide.
