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.
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.
International Standard ISO 11960 was prepared by Technical Committee ISO/TC 67, Materials, equipment and
offshore structures for petroleum and natural gas industries, Subcommittee SC 5, Casing, tubing and drill pipe.
This second edition replaces the first edition (ISO 11960:1996) which has been technically revised. It is the intent of
TC 67 that the first and second editions of ISO 11960 both be applicable, at the user's option, for a period of six
months after the date of publication of this second edition, after which the first edition will no longer be applicable.
Annexes A to E form a normative part of this International Standard. Annexes F and G are for information only.

Introduction
This International Standard is based on API 5CT (Specification for Casing and Tubing).
Users of this International Standard should be aware that further or differing requirements may 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 may be
particularly applicable where there is innovative or developing technology. Where an alternative is offered, the
vendor should 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;
� MAYis usedto indicatethat aprovision is OPTIONAL.

INTERNATIONAL STANDARD ISO 11960:2001(E)
Petroleum and natural gas industries — Steel pipes for use as
casing or tubing for wells
1 Scope
1.1 This International Standard specifies the technical delivery conditions for steel pipes (casing, tubing, plain
end casing liners and pup-joints) and accessories. This International Standard is applicable to the following
connections in accordance with ISO 10422 or API Spec 5B:
� short round thread casing (STC);
� long round thread casing (LC);
� buttress thread casing (BC);
� extreme-line casing (XC);
� non-upset tubing (NU);
� external upset tubing (EU);
� integral joint tubing (IJ).
For such connections, this International Standard specifies the technical delivery conditions for couplings and
thread protection.
For pipes covered by this International Standard, the sizes, masses, wall thicknesses, grades and applicable end
finishes are defined.
This International Standard may also be applied to tubulars with connections not covered by ISO/API standards.
1.2 The four groups of products to which this International Standard is applicable include the following grades of
pipe:
� Group 1: All casing and tubing in Grades H, J, K and N;
� Group 2: All casing and tubing in Grades C, L, M and T;
� Group 3: All casing and tubing in Grade P;
� Group 4: All casing in Grade Q.
1.3 Casing sizes larger than Label 1: 4-1/2 but smaller than Label 1: 10-3/4 may be specified by the purchaser to
be used in tubing service, see Tables C.1, C.24, C.30 and C.31 or Tables E.1, E.24, E.30 and E.31.
1.4 Supplementary requirements that may optionally be agreed between purchaser and manufacturer, for non-
destructive examination, coupling blanks, upset casing, electric-welded casing, impact testing, seal ring couplings
and certificates are given in annex A.
1.5 This International Standard is not applicable to threading requirements.
NOTE Dimensional requirements on threads and thread gauges, stipulations on gauging practice, gauge specifications, as
well as instruments and methods for inspection of threads are given in ISO 10422 or API Spec 5B. Connections machined to
either of these specifications are the same for practical purposes and are totally interchangeable.

2 Conformance
2.1 Normative references
In the interests of worldwide application of this International Standard, ISO/TC 67 has decided, after detailed
technical analysis, that certain of the normative documents listed in clause 3 and prepared by ISO/TC 67 or other
ISO Technical Committee are interchangeable in the context of the relevant requirement with the relevant
document prepared by the American Petroleum Institute (API), the American Society for Testing and Materials
(ASTM) or the American National Standards Institute (ANSI). These latter documents are cited in the running text
following the ISO reference and preceded by “or”, for example “ISO XXXX or API YYYY”. Application of an
alternative normative document cited in this manner will lead to the same results as the use of the preceding
ISO reference. These documents are thus considered interchangeable in practice.
2.2 Units of measurement
In this International Standard, data are expressed in both the International System (SI) of units and the United
States Customary (USC) system of units. For a specific order item, it is intended that only one system of units be
used, without combining data expressed in the other system.
Products manufactured to specifications expressed in either of these unit systems shall be considered equivalent
and totally interchangeable. Consequently, compliance with the requirements of this International Standard as
expressed in one system provides compliance with requirements expressed in the other system.
For data expressed in the SI, a comma is used as the decimal separator and a space as the thousands separator.
For data expressed in the USC system, a dot (on the line) is used as the decimal separator and a space as the
thousands separator.
In the text, data in SI units are followed by data in USC units in brackets.
2.3 Tables and figures
Separate tables for data expressed in SI units and USC units are given in annex C and annex E respectively. For a
specific order item, only one unit system shall be used.
Figures are contained in annex D and express data in both SI and USC units.
3 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
