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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 17078-4 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.

Introduction
This part of ISO 17078 has been developed by users/purchasers and suppliers/manufacturers of subsurface
side-pocket mandrels, flow-control devices used in side-pocket mandrels (hereafter called flow-control
devices), and associated latches and installation tools that are used in conjunction with side-pocket mandrel
flow-control devices. This equipment is intended for use in the worldwide petroleum and natural gas industry.
This part of ISO 17078 is intended to provide supporting information, guidelines and practices to all parties
who are involved in the specification, selection, manufacture, testing and use of side-pocket mandrels,
flow-control devices and associated latches and installation tools.
In addition to this part of ISO 17078, ISO 17078-1 provides requirements for side-pocket mandrels used in the
petroleum and natural gas industry. ISO 17078-2 provides requirements for flow-control devices. And,
ISO 17078-3 provides requirements for latches and installation tools that are used in conjunction with
side-pocket mandrel flow-control devices. Other pertinent side-pocket mandrel-related information can be
found in API standards listed in the bibliography.
It is necessary that users of this part of ISO 17078 be aware that requirements above those outlined in this
part of ISO 17078 can be needed for individual applications. This part of ISO 17078 is not intended to inhibit a
supplier/manufacturer from offering, or the user/purchaser from accepting, alternative equipment or
engineering solutions. This can be particularly applicable where there is innovative or developing technology.
Where an alternative is offered, it is the responsibility of the supplier/manufacturer to identify any variations

ISO 17078-4:2010(E)
Annex A
(informative)
Interface compatibility issues
A.1 General
This annex presents guidelines for interface compatibility issues between side-pocket mandrels and related
equipment. It is the responsibility of the user/purchaser to assure compatibility between the various tools if
components are selected from different suppliers/manufacturers.
A.2 Interface compatibility
A.2.1 General
Each component in a gas-lift or side pocket equipment system, including the side-pocket mandrel, flow-control
device and the tools used for installation and retrieval (running, pulling, and kick-over tool, and latch) shall be
dimensionally compatible with each other to work correctly. Normally, dimensional compatibility between
components is only assured within the product line of a particular supplier/manufacturer, unless a
supplier/manufacturer runs specific tests to demonstrate compatibility with components from a different
supplier/manufacturer with which compatibility is claimed. Examples of such tests are provided in this
International Standard (all parts).
If a user/purchaser chooses to use equipment from different suppliers/manufacturers, the user/purchaser can
require that dimensional compatibility between the components be proven. A recommended way to do this is
to require that the suppliers/manufacturers demonstrate dimensional compatibility by performing interface
validation tests.
A.2.2 Validated compatibility
All components are made by one supplier/manufacturer, and that supplier/manufacturer proves, through ISO-
specified design validation compatibility testing, that all of its components fit and work together.
A.2.3 Claimed compatibility
Components are provided by different suppliers/manufacturers, but each supplier/manufacturer has proven
compatibility with each component for which compatibility is claimed. The ISO-specified functional
compatibility tests are a recommended way to do this.
A.2.4 Unconfirmed compatibility
Components are provided by several different suppliers/manufacturers that do not claim interface compatibility.
In this case, interface compatibility of all components should be demonstrated by functional testing before
installation. The ISO-specified functional compatibility tests are a recommended way to do this.
A.2.5 Degree of assurance by different design validation grades
For most components, the ISO standards provide differing “degrees of assurance” by the design validation
grades V3, V2, and V1 for side-pocket mandrels, flow-control devices, latches and associated tools. Each
user/purchaser shall be aware of the requirements of each grade and specify the grade necessary to assure
the interface compatibility that is required. For some components, grade V1 requires a tolerance-accumulation
study with all required tolerances, including the specific design tolerances of the side-pocket mandrel, the
flow-control device and the latch. It is unlikely that this requirement can be met in cases where components
are provided by different suppliers/manufacturers.

Annex B
(informative)
Test facilities for flow-control device performance testing
WARNING — The use of this part of ISO 17078 can involve hazardous operations and equipment. This
part of ISO 17078 does not purport to address all of the safety problems associated with its use. It is
the responsibility of the user of this part of ISO 17078 to establish appropriate skill levels for
personnel performing the procedures and the applicability of safety and health practices.
B.1 Scope
This annex provides recommendations for test facilities used in performance testing of flow-control devices. It
outlines the equipment required for testing flow-control devices to determine
a) the flow-control device flow coefficients, C ;
v
b) the pressure-drop ratio factor, X ;
t
c) the gas-lift flow-control-device performance curves.
B.2 Test facility
B.2.1 General guidelines
B.2 outlines the testing facility necessary to perform flow-control device testing. The type of testing anticipated
requires a high-volume, high-pressure source of gas. It is suggested that the gas storage device be at least
3 3
2,83 m (100 ft ) and the pressure be at least 10 432 kPa (1 500 psi).
Applicable codes and practices should be followed when constructing the facility. The piping, flow-control
devices and surge vessels that comprise the gas-lift flow-control-device testing system are subjected to
high-pressure gas. Therefore, the fabrication, testing, and flow-control device selections shall adhere to the
established codes governing piping systems and vessels.
Surge or other vessels with diameters exceeding 152 mm (6 in) shall adhere to ANSI/ASME BPVC,
Section VIII, Divisions 1 and 2. These provide requirements for design, fabrication, inspection and certification
of applicable vessels.
The specifications for piping, including materials, wall thickness and related pressure ratings, shall be in
accordance with ANSI/ASME B31.8, Gas Transmission and Distribution Piping Systems and addenda. Piping
material shall be specified as Grade B; flanges shall be in accordance with ANSI/ASME B16.5, Pipe Flanges
and Flanged Fittings: NPS 1/2 through 24" and any addenda; flow-control devices shall be in accordance with
ANSI/ASME B16.34, Valves Flanged, Threaded and Welding End.
Other components are covered by ISO 14313.
NOTE For the purposes of this provision, API Spec 6D is equivalent to ISO 14313.
These components may be used; however, it is possible that they are not interchangeable with ANSI/ASME
flanges, so caution should be used if attempting to mix equipment covered by different codes.
All testing shall be performed by personnel who have been qualified as having the required skills and abilities
to conform to the requirements of this part of ISO 17078.

each series of testing performed. This documentation shall be available for review by the user/purchaser for a
minimum of three years after completion of the processing.
B.2.2 Calibration
Measuring and testing equipment used for acceptance shall be identified, inspected, calibrated and adjusted
at specific intervals in accordance with the documented specifications of ISO/IEC 17025, this part of
ISO 17078 or an applicable national or international standards agency that is no less stringent than the
requirements included herein.
NOTE For the purposes of this provision, ANSI/NCSL Z540-3 is equivalent to ISO/IEC 17025.
Measuring and testing equipment shall be used only within the calibrated range.
Technologies for inspections with verifiable accuracies equal to or better than those listed in this part of
ISO 17078 may be applied with appropriate documentation and when approved by qualified personnel.
Calibration intervals for measuring and testing equipment shall be established based on repeatability and
degree of usage. Calibration intervals shall be a maximum of three months until recorded calibration history
can be established. Intervals may be lengthened or shortened based on documented repeatability, amount of
usage and calibration history. The calibration interval cannot be increased by more than twice the previous
interval, not to exceed one year.
Calibration standards used to calibrate measuring equipment shall be checked and approved at least once a
year by an independent agency with traceability to the applicable national or international standards agency.

B.2.4 Test specimen — Wireline-retrievable flow-control devices
B.2.4.1 Test specimen
The test specimen includes the fully assembled test flow-control device including the supplier/manufacturer's
recommended reverse check valve and a latch that is compatible with the flow-control device. This assembly
is installed and latched in a compatible receptacle. Replacement of the external V-ring packing stacks with an
alternate method of sealing is permissible.
The flow-control-device receptacle shall be compatible with the flow-control device and latch; it shall provide a
means to seal above and below the flow-control-device inlet ports. The inlet port area of the receptacle and
the minimum annular flow area between the receptacle and flow-control-device inlet port shall be recorded.
The test specimen consists of the components shown in Figure B.2.

B.2.4.2 Test section — General
The test section includes the test specimen and all fixtures located between the upstream and downstream
pressure measurement devices. The flow path through the test section shall not pass through any chokes,
close-radius elbows or tees, and shall be free of internal obstructions. Elbows shall have a minimum radius of
10,16 cm (4 in). Figure B.3 shows an example of a test section that complies with these provisions.

B.2.4.3 Upstream test section
The test section upstream of the test specimen shall extend no more than 60,96 cm (24 in) from the test
specimen and shall have a minimum inside flow diameter of at least 2,54 cm (1 in). The upstream test section
shall be plumbed to the test specimen such that an unobstructed annular chamber exists surrounding the inlet
ports of the test specimen. This chamber shall extend no less than 1,27 cm (0,5 in) above and below the inlet
ports of the test specimen and shall have an annular width of at least 0,64 cm (0,25 in).
B.2.4.4 Downstream test section
The test section downstream of the test specimen shall extend no more than 60,96 cm (24 in) from the test
specimen and shall have an inside diameter of at least 3,81 cm (1,5 in). The downstream test section shall be
aligned such that the centrelines of the specimen and section are parallel and concentric. The downstream
test section shall have a straight extension of at least 15,24 cm (6 in) length beginning at the test specimen.
B.2.5 Upstream and downstream control valves
Upstream and downstream control valves are used to control or throttle the pressures acting on the test
section. Both control valves shall be of sufficient flow rate and pressure capacity to exceed the flow rate and
pressure capacity of the test system.
B.2.6 Pressure surge protection
B.2.6.1 General
Pressure surge protection is recommended on both the upstream and downstream side of the test section.
The purpose of the pressure surge protection is to dampen the effects of a pressure surge that could possibly
occur as a result of flow-control-device performance. Pressure surge has the potential to cause serious
damage to pressure-measuring devices and transducers, and seriously hamper the ability to control and
monitor a test.
B.2.6.2 Surge tanks
Surge tanks can be used to gain an amount of surge protection. These tanks shall be plumbed into the test
system outside the test section such that they are each independently in full pressure communication with the
upstream and downstream pressures acting on the test section. Optional control valves may be placed in the
plumbing that connects the pressure surge tanks to the test system. The volume of the pressure surge tanks
3 3
shall be no less than 0,057 m (2 ft ). It is recommended that the downstream pressure surge tank have twice
the volume of the upstream pressure surge tank.
B.2.6.3 Alternative methods
Alternative surge protection systems that reduce pressure surges in the test specimen to no more than
69 kPa/s (10 psi/s) are also permitted.
B.2.7 Flow measurement methods and accuracy
The flow measurement instrument and/or method may be any device that meets the specified accuracy.
Flow rate shall be determined within an error not exceeding ±5 % of actual flow rate. The resolution and
repeatability of the method shall be within ±0,5 % of actual flow rate. The measuring instrument shall be
selected and maintained to achieve the specified accuracy. The ANSI/API MPMS 14.31-1990 or GPA 8185-90
Part 1 methods of flow-rate calculation, along with a certified meter run, satisfy these provisions.
