Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO 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 closely 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 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). www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent 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). www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the World
Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT),
see www.iso.org/iso/foreword.html. www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 220, Cryogenic vessels., in collaboration
with the European Committee for Standardization (CEN) Technical Committee CEN/TC 268, Cryogenic
vessels, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This second edition cancels and replaces the first edition (ISO 21011:2008), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— — Update of the Scope to change upper end of size from DN 150 to DN 200;
— — Clarification of the use of pressure units;
— — Revision of the type approval tests;
— — Revision of Clause 7,Clause 7, “Marking”.
— — Revised formula in Annex AAnnex A to take into account atmospheric pressure in dead volume at
initial condition.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Cryogenic vessels – — Valves for cryogenic service
1 Scope
This document specifies the requirements for the design, manufacture and testing of valves for a rated
temperature of −40 °C and below (cryogenic service), i.e. for operation with cryogenic fluids in addition
to operation at temperatures from ambient to cryogenic.
This document is applicable to all types of cryogenic valves, including vacuum jacketed cryogenic valves
up to size DN 200.
This document can be used as guidance for larger size valves.
This document is not applicable to pressure relief valves covered by ISO 21013-1.
