ČSN EN ISO 21009-2 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. |
