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 14310 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.
This second edition cancels and replaces the first edition (ISO 14310:2001), which has been technically

Introduction
This International Standard has been developed by users/purchasers and suppliers/manufacturers of packers
and bridge plugs and is intended for use in the petroleum and natural gas industry worldwide. This
International Standard is intended to give requirements and information to both parties in the selection,
manufacture, testing and use of packers and bridge plugs. Further, this International Standard addresses
supplier/manufacturer requirements that set the minimum requirements with which it is necessary that
suppliers/manufacturers comply to claim conformity with this International Standard.
This International Standard has been structured to allow for grades of increased requirements both in quality
control and design validation. These variations allow the user/purchaser to select the grade required for a
specific application.
The three quality grades provide the user/purchaser with a choice of requirements to meet a specific
preference or application. Quality grade Q3 is the minimum grade of quality offered by this product standard.
Quality grade Q2 provides additional inspection and verification steps, and quality grade Q1 is the highest
grade provided. Additional quality requirements can be specified by the user/purchaser as supplemental
requirements.
Seven standard design-validation grades (V0 to V6) provide the user/purchaser with a choice of requirements
to meet a specific preference or application. Design validation grade V6 is the minimum grade and represents
equipment where the validation method has been defined by the supplier/manufacturer. The complexity and
severity of the validation testing increases as the grade number decreases.
It is necessary that users of this International Standard be aware that requirements above those outlined in
this International Standard can be needed for individual applications. This International Standard 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 necessary that the supplier/manufacturer identify
any variations from this International Standard.

in the validation-tested product. Pre-test and post-test dimensional inspection of critical operational areas, as
determined by the supplier/manufacturer, shall be conducted, documented and maintained by the
supplier/manufacturer. Validation test results and dimensional inspection results shall be approved by a
qualified person other than the person performing them and records of the results shall become a portion of
the design documentation.
The validation grades are the following:
⎯ V6: supplier/manufacturer-defined;
⎯ V5: liquid test;
⎯ V4: liquid test plus axial loads;
⎯ V3: liquid test plus axial loads plus temperature cycling;
⎯ V2: gas test plus axial loads;
⎯ V1: gas test plus axial loads plus temperature cycling;
⎯ V0: gas test plus axial loads plus temperature cycling plus zero bubble acceptance criterion.
Bridge plugs may be run and tested without axial load; however, all validation grades are applicable.
Products qualified to higher grades of design validation may be considered qualified for the lower grades of
design validation in accordance with Table 1.
Packers or bridge plugs validated to grade V5 through grade V0 shall not be rated for use in casing or tubing
sizes and masses (weights) that can have a maximum ID larger than the ID used in the validation test.

6.5.2.2 Grade V6 — Supplier/manufacturer-defined
The supplier/manufacturer defines the validation method and acceptance criteria.
6.5.2.3 Grade V5 — Liquid test
The supplier/manufacturer shall adhere to the following test parameters and criteria for conformance to this
validation grade.
⎯ Set in maximum rated casing or tubing ID ± 0,76 mm (± 0,030 in) (see 6.5.1).
⎯ Set with the minimum rated setting force or pressure (± 10 %).
⎯ Test products with inflatable packing elements horizontally. Centralization at one end of the test fixture is
acceptable.
⎯ Products with no anchoring devices or anchoring devices that hold in one direction may be restrained by
the test fixture to prevent movement in the un-anchored direction(s).
⎯ Set and run entire test at or above maximum rated temperature.
⎯ Test at or above maximum rated differential pressure.
⎯ Perform a minimum of two pressure reversals at or above maximum rated pressure from above to below
or vice versa.
⎯ Use a liquid test medium of water, with or without additives, or hydraulic oil. The density shall be less than
3 3
1 100 kg/m (68,67 lb/ft ). Liquid shall be visibly free from particulate matter or other material that can
plug a small leak.
⎯ Maintain a minimum hold period of 15 min for pressure tests.
⎯ Acceptance criterion: no more than 1 % reduction in the maximum rated differential pressure over the
hold period after sufficient time has been allowed for stabilization. Time period for stabilization is at the
discretion of the supplier/manufacturer.
⎯ Use the supplier's/manufacturer's specified methods to remove the retrievable-type packers/bridge plugs
at the end of the test.
6.5.2.4 Grade V4 — Liquid plus axial load test
The supplier/manufacturer shall adhere to the following test parameters and criteria for conformance to this
validation grade.
⎯ Set in maximum rated casing or tubing ID ± 0,76 mm (± 0,030 in) (see 6.5.1).
⎯ Set with the minimum rated setting force or pressure (± 10 %).
⎯ Test products with inflatable packing elements horizontally. Centralization at one end of the test fixture is
acceptable.
⎯ Products with no anchoring devices or anchoring devices that hold in one direction may be restrained by
the test fixture to prevent movement in the un-anchored direction(s).
⎯ Set and run the entire test at or above the maximum rated temperature.
⎯ Test at or above the maximum rated differential pressure.
ISO 14310:2008(E)
⎯ Perform a minimum of two pressure reversals at or above the maximum rated pressure from above to
below or vice versa.
⎯ Test to all intersection points of the rated performance envelope.
⎯ Test those packers or bridge plugs having shear-release features at their maximum rated shear load. For
safety, the shear device can be replaced with a stronger shear device that can adequately withstand the
maximum shear load.
⎯ Use a liquid test medium of water, with or without additives, or hydraulic oil. The density shall be less than
3 3
1 100 kg/m (68,67 lb/ft ). Liquid shall be visibly free from particulate matter or other material that can
plug a small leak.
⎯ Maintain a minimum hold period of 15 min for pressure tests.
⎯ Acceptance criterion: no more than 1 % reduction in the maximum rated differential pressure over the
hold period after sufficient time has been allowed for stabilization. The time period for stabilization is at
the discretion of the supplier/manufacturer.
⎯ Use the supplier's/manufacturer's specified methods to remove the retrievable-type packers/bridge plugs
