The work of preparing International Standards is normally carried out through ISO

26、 technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates cl

27、osely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria

28、 needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of pat

29、ent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used

33、ulated vessels Part 2: Operational requirements1 ScopeThis 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

34、 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 re-installed by another party, such as the operator, user or owner.

35、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 requi

36、rements of this International Standard and any applicable local regulation, the local 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.
