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 3.
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 International Standard 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 and natural gas industries, Subcommittee SC 4, Drilling and production equipment.
Annex A forms a normative part of this International Standard.

Introduction
This International Standard has been developed by users/purchasers and suppliers/manufacturers of packers and
bridge plugs 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 which
set the minimum parameters with which suppliers/manufacturers shall comply to claim conformity with this
International Standard.
This International Standard has been structured with 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 control grades provide the user/purchaser the choice of requirements to meet a specific
preference or application. Quality control grade Q3 is the minimum grade of quality offered by this product
standard. Quality control grade Q2 provides additional inspection and verification steps, and quality control grade
Q1 is the highest grade provided. Additional quality upgrades can be specified by the user/purchaser as
supplemental requirements.
Six standard design validation grades (V1 to V6) and one special design validation grade (V0) provide the
user/purchaser the 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.
Design validation grade V6 and quality control grade Q3 represent equipment designed and manufactured
consistent with minimum industry practice. These grades are sufficient for a number of applications; however, some
applications could require and justify the higher grades of quality control and design validation defined by this
International Standard.
Users of this International Standard should be aware that requirements above those outlined in this International
Standard may 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 may be particularly applicable where there is innovative or developing technology. Where an
alternative is offered, the supplier/manufacturer should identify any variations from this International Standard and
provide details.
