Overview
EN ISO 17078-2:2026 specifies requirements for subsurface flow-control devices used in side-pocket mandrels for the global oil, gas, and lower carbon energy industries. Developed by CEN and aligned with ISO 17078-2:2026, this standard addresses the specification, design, manufacturing, quality control, and testing of flow-control devices such as injection-pressure-operated (IPO), production-pressure-operated (PPO), pilot, orifice, tubing-retrievable, and dummy flow-control devices. It also covers performance testing and calibration requirements to ensure equipment reliability and operational safety.
This document supplements requirements from API Spec 19G2, 2nd edition (2020), with additional provisions specific to European and international industry needs. It does not address installation, retrieval, or reconditioning of devices, nor does it apply to concentric-axis devices, side-pocket mandrels, or running/pulling tools.
Key Topics
Types of Flow-Control Devices: The standard covers multiple device types used for various applications in oil and gas wells, including:
- Injection-pressure-operated (IPO)
- Production-pressure-operated (PPO)
- Pilot-operated
- Orifice and Venturi types
- Tubing-retrievable devices
- Dummy (blanking) devices
Design and Manufacture Requirements: Ensures all flow-control devices meet strict criteria for selection, design, materials, manufacturing processes, and dimensional tolerances. Emphasizes compatibility with side-pocket mandrels and well environments.
Quality Control and Testing: Provides detailed requirements for quality management (referencing ISO 9000), validation testing, functional testing, performance assessments, and calibration. Devices are subject to a range of tests including pressure, leakage, durability, and flow validation, ensuring compliance with the highest safety and reliability standards.
Compliance and Supplementation: Aligns with and supplements API Spec 19G2, 2nd edition, ensuring both global and regional regulatory requirements are met. Calls for the use of ISO 17078-1, -3, and -4 for related equipment and practices.
Applications
EN ISO 17078-2:2026 applies across the upstream oil and gas sector, including operations focused on:
- Gas Lift and Well Intervention: Provides standards for devices essential in gas lift systems, which improve production efficiency and manage wellbore pressures.
- Production Optimization: Flow-control devices help regulate injection and production flows, maximizing hydrocarbon recovery while minimizing operational risk.
- Well Integrity Assurance: Devices meeting the requirements of ISO 17078-2:2026 help maintain well control and containment, reducing risks associated with leaks or equipment failure.
- Lower Carbon Energy Initiatives: Applicable to emerging fields within lower-carbon operations where side-pocket mandrel technology is used for efficient resource management.
Manufacturers, suppliers, and operators in the petroleum and natural gas industry rely on this standard to ensure product integrity, safety, and interoperability. The requirements facilitate seamless integration and reliable performance of flow-control devices in various well conditions worldwide.

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.
