This document specifies operational requirements for static vacuum insulated vessels designed for a maximum allowable pressure of more than 50 kPa (0,5 bar). It can also be used as a guideline for vessels designed for a maximum allowable pressure of less than 50 kPa (0,5 bar).
This document applies to vessels designed for cryogenic fluids specified in ISO 21009‑1.
Static cryogenic vessels are often partly equipped by the manufacturer, but can be installed or re- installed by another party, such as the operator, user or owner.
NOTE 1 For the installation of these vessels, additional requirements can apply.
NOTE 2 Some requirements of this document can be covered by local regulations, e.g. safety distances, occupational safety and health.
NOTE 3 Additional requirements can apply to the operation of large scale and field-fabricated vessels.
