Cryogenic vessels. Static vacuum insulated vessels - Operational requirements1 Scope This part of ISO 21009 specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 50 kPa (0,5 bar). It may also be used as a guideline for vessels designed for a maximum allowable pressure of less than 50 kPa (0,5 bar). This part of ISO 21009 applies to vessels designed for cryogenic fluids specified in ISO 210091. Static cryogenic vessels are often partly equipped by the
