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).
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).
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.
This document was prepared by Technical Committee [or Project Committee] ISO/TC [or ISO/PC] 67,
Subcommittee SC4.
This second edition cancels and replaces the first edition (ISO 17078-2:2009), which has been technically
revised.
This document supplements API [SPECIFICATION 19G2], 2nd edition (2020).
The technical requirements of this document and API [SPECIFICATION 19G2] used to be identical. In the
meantime API [SPECIFICATION 19G2-2010] has been technically revised as API [SPECIFICATION 19G2], 2nd
edition (2020). The purpose of this edition of ISO 17078-2[2024]is to bring it up to date, by referencing the
current edition of API [SPECIFICATION 19G2-2020 and including supplementary content.
The main changes compared to the previous edition are as follows:
— Tubing-retrievable flow-control devices were added into the Scope.
— ISO 9000, ISO 17078-1, ISO 17078-3, ISO 17078-4 and ISO 7-1 were added in 2 Normative references and
API Q1, API 19G1, API 19G3 and API 19G4 deleted.
— The definition of tubing-retrievable flow-control devices was added in 3 Terms and definitions.
— The description of tubing-retrievable flow-control devices was added in Table 1, 6 Technical specification.
— The design optimization of tubing-retrievable flow-control devices was added in 6.3.9 Good design
practice.
— The requirements for testing of tubing-retrievable flow-control devices were added in Annex C.
A list of all parts in the ISO17078 series can be found on the ISO website.
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.
