NF EN ISO 21009-2, E86-504-2 (10/2024)

ISO 21009-2:2015 specifies operating requirements for stationary vacuum-insulated cryogenic vessels designed for a maximum allowable pressure greater than 50 kPa (0.5 bar). It can also be used as a guide for vessels designed for a maximum allowable pressure less than 50 kPa (0.5 bar). ISO 21009-2:2015 applies to containers designed for cryogenic fluids as specified in ISO 21009-1. Fixed cryogenic vessels are often partially equipped by the manufacturer, but they can be installed or reinstalled by another party, such as the operator, user or owner. NOTE 1 For the installation of the containers in question, additional requirements may apply; they are defined in specific regulations. NOTE 2 A number of requirements relating to this standard may be addressed by local regulations, for example, safety distances, occupational safety and health. In the event of a conflict between this International Standard and any applicable local regulations, the local regulations always prevail.
