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 16070 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.
The requirements of this International Standard supersede the requirements for lock mandrels and landing nipples
specified in ISO 10432:1999.
Annexes A and B of this International Standard are for information only.

ISO 16070:2001(E)
Introduction
This International Standard has been developed by users/purchasers and suppliers/manufacturers of lock mandrels
and landing nipples 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 lock mandrels and landing nipples. Furthermore, this International Standard addresses the minimum
requirements with which the supplier/manufacturer is to comply so as to claim conformity with this International
Standard.
This International Standard has been structured to allow for grades of increased requirements in quality control and
design validation. These variations allow the user/purchaser to select the grade required for a specific application.
There are three quality control grades which provide the user/purchaser the choice of requirements to meet specific
preference or application. Quality control grade Q3 is the minimum grade of quality offered by this International
Standard. Quality control grade Q2 provides additional inspection and verification steps and quality control grade
Q1 is the highest grade provided.
There are three design validation grades which provide the user/purchaser the choice of requirements to meet
specific preference or application. Design validation grade V3 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.
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.
