ISO 21009-2:2015 PDF

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 21009-1. Static cryogenic vessels are often partly equipped by the manufacturer, but may be installed or reinstalled by another party, such as the operator, user or owner. NOTE 1 For the installation of these vessels, additional requirements can apply; 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 local regulation always takes precedence.
