Overview

This standard 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. For the installation of these vessels, additional requirements may apply; these are defined in specific regulations. Some requirements of this standard can be covered by local regulations, for example 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. The committee responsible for this standard is Working Committee NA 016-00-05 AA "Kryo-Behälter; Spiegelausschuss zu CEN/TC 268 und ISO/TC 220" ("Cryogenic vessels; National mirror committee to CEN/TC 268 and ISO/TC 220") at DIN Standards Committee Pressurized Gas Installations (NDG).
