33、ifies 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

34、 designed for cryogenic fluids specified in ISO 21009-1.Static cryogenic vessels are often partly equipped by the manufacturer, but may 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;

35、these are defined in specific regulations.NOTE 2 Some requirements of this standard can be covered by local regulations, e.g. safety distances, occupational safety and health. Where there is a conflict between the requirements of this International Standard and any applicable local regulation, the l

36、ocal regulation always takes precedence.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
