32、cally revised.ISO 21009 consists of the following parts, under the general title Cryogenic vessels Static vacuum insulated vessels: Part 1: Design, fabrication, inspection and tests Part 2: Operational requirementsDIN EN ISO 21009-2:2016-05 EN ISO 21009-2:2015 (E)4 1 ScopeThis part of ISO 21009 spec
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. For dated references, only the edition cited applies. For undated references, the latest editi
