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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of this document, ISO had not received
notice of (a) patent(s) which may be required to implement this document. However, implementers are
cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents. ISO shall not be held responsible for identifying any or all
such patent rights.
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 ISO/TC 67, Oil and gas industries including lower
carbon energy, Subcommittee SC 4, Drilling, production and injection equipment, in collaboration with the
European Committee for Standardization (CEN) Technical Committee CEN/TC 12, Oil and gas industries
including lower carbon energy, in accordance with the Agreement on technical cooperation between ISO
and CEN (Vienna Agreement).
This first edition cancels and replaces ISO 15551-1:2015, which has been technically revised.
The main changes are as follows:
— the relationship between the design verification/validation activities and the functional
specification/technical specification has been revised. In this document, the design verification/
validation activities have been tied to a “basis of design” rather than to the functional specification/
technical specification;
— Annex E has been augmented to incorporate additional details, guidelines and options for completing
functional evaluation of assembled systems;
— Annex L is a “user’s guide”, which has been added to this document to provide a simplified view of
the practical workflow of the document.
Any feedback or questions on this document should be directed to the user’s national standards body. A

device used to keep the electrical submersible pump assembly or other downhole equipment in the
centre of the tubing, casing or wellbore
3.22
centrifugal pump
component of an electrical submersible pump system that uses rotating impeller(s) to impart kinetic
