Petroleum and natural gas industries - Steel pipes for use as casing or tubing for wells (ISO 11960:2011)
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. For pipes covered by this International Standard, the sizes, masses and wall thicknesses as well as grades and applicable end-finishes are listed in Tables C.1 and C.2 and Tables E.1 and E.2. By agreement between the purchaser and manufacturer, this International Standard can also be applied to other plain-end pipe sizes and wall thicknesses.

Industrija za predelavo nafte in zemeljskega plina - Jeklene cevi, ki se uporabljajo kot zaščitne cevi ali cevovodi za vrtine (ISO 11960:2011)
Ta mednarodni standard določa tehnične dobavne pogoje za jeklene cevi (ohišje, cevi in spoje), zaloge spojk, spojni material in dodatno opremo in zahteve za tri ravni specifikacije proizvoda (PSL-1, PSL-2, PSL-3). Zahteve za PSL-1 so osnova tega mednarodnega standarda. Zahteve, ki določajo različne ravni standardnih tehničnih zahtev za PSL-2 in PSL-3, za vse razrede, razen H-40, L-80 9Cr in C110, so zajete v dodatku H. Za cevi, ki jih zajema ta mednarodni standard, so velikosti, mase in debeline sten ter razredi in ustrezna končna obdelava, navedeni v preglednicah C.1 in C.2 ter E.1 in E.2. Po dogovoru med kupcem in proizvajalcem se lahko ta mednarodni standard uporablja tudi za druge cevi z navadnim zaključkom različnih velikosti in debeline sten.

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 11960 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 5, Casing, tubing and drill pipe.
This fourth edition cancels and replaces the third edition (ISO 11960:2004) and its Technical Corrigendum
ISO 11960:2004/Cor.1:2006, which have been extensively technically revised.
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.
This International Standard has also been published in a marked version indicating changes from the previous
edition.

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. 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.

INTERNATIONAL STANDARD ISO 11960:2011(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 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.
For pipes covered by this International Standard, the sizes, masses and wall thicknesses as well as grades
and applicable end-finishes are listed in Tables C.1 and C.2 and Tables E.1 and E.2.
By agreement between the purchaser and manufacturer, this International Standard can also be applied to
other plain-end pipe sizes and wall thicknesses.
This International Standard is applicable to the following connections in accordance with API Spec 5B:
⎯ short round thread casing (SC);
⎯ long round thread casing (LC);
⎯ buttress thread casing (BC);
⎯ non-upset tubing (NU);
⎯ external upset tubing (EU);
⎯ integral tubing connections (IJ).
For such connections, this International Standard specifies the technical delivery conditions for couplings and
thread protection. Supplementary requirements that can optionally be agreed for enhanced leak resistance
connections (LC) are given in A.11 SR22.
This International Standard can 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, N and R;
⎯ Group 2: All casing and tubing in Grad
