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 on the meaning of ISO specific terms and expressions related to conformity assessment,

The committee responsible for this document is ISO/TC 67, Materials, equipment and offshore structures for
petroleum and petrochemical and natural gas industries, Subcommittee SC 5, Casing, tubing and drill pipe.
This fifth edition cancels and replaces the fourth edition (ISO 11960:2011).
It is the intention of ISO/TC 67 that either this edition or the previous edition of ISO 11960 be applicable, at the
option of the purchaser (as defined in 4.1.39), for a period of six months from the first day of the calendar
quarter immediately following the date of publication of this edition, after which period the previous edition will
no longer be applicable.

Introduction
This International Standard is based on API Spec 5CT.
Users of this International Standard are advised that further or differing requirements can be needed for
individual applications. This International Standard is not intended to inhibit a vendor from offering, or the
purchaser from accepting, alternative equipment or engineering solutions for the individual application. This
can be particularly applicable where there is innovative or developing technology. Where an alternative is
offered, it is advisable that the vendor identify any variations from this International Standard and provide
details.
This International Standard includes requirements of various nature. These are identified by the use of certain
verbal forms:
 SHALL is used to indicate that a provision is MANDATORY;
 SHOULD is used to indicate that a provision is not mandatory, but RECOMMENDED as good practice;
 MAY is used to indicate that a provision is OPTIONAL.
Details of the major changes (additions, modifications and deletions) agreed by the committee, and which
affect the performance of the products or the technical requirements applicable to the products, are provided
for information in Annex L and are indicated in this International Standard by the use of grey shading for
changes in the fourth edition and yellow shading for changes in this edition. Shading is also used to indicate
editorial changes. Where deletions, but no other changes, have been made, vertical bars are used in the
margin adjacent to the applicable line or at each side of a cell in a table. Where a complete line or paragraph
has been deleted, margin bars next to a blank line are used. While efforts have been made to ensure the
accuracy of the changes indicated, the user of this International Standard is advised to consider the total
technical content and not only the changes identified. The user is ultimately responsible for recognising any
differences between this edition and the previous edition of this International Standard. ISO expressly
disclaims any liability or responsibility for loss or damage resulting from inappropriate use of this International
Standard on the basis of any inaccuracy in the changes identified.

1 Scope
1.1 This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing and
pup joints), coupling stock, coupling material and accessory material and establishes requirements for three
Product Specification Levels (PSL-1, PSL-2, PSL-3). The requirements for PSL-1 are the basis of this
International Standard. The requirements that define different levels of standard technical requirements for
PSL-2 and PSL-3, for all Grades except H-40, L-80 9Cr and C110, are contained in Annex H.
