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 15463 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.
vi © ISO 2003 – All rights reserved
Introduction
This International Standard is provided for field inspection and testing of OCTG; it is not intended to restrict
the agency or owner from using personal judgement and supplementing the specified inspections with other
techniques, extending existing techniques, or re-inspecting certain lengths of OCTG.
Users of this International Standard should be aware that further or differing requirements might 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.
INTERNATIONAL STANDARD ISO 15463:2003(E)
Petroleum and natural gas industries — Field inspection of new
casing, tubing and plain-end drill pipe
1 Scope
This International Standard specifies requirements and gives recommendations for field inspection and testing
of oil country tubular goods (OCTG). This International Standard covers the practices and technology
commonly used in field inspection; however, certain practices may also be suitable for mill inspections.
This International Standard covers the qualification of inspection personnel, a description of inspection
methods and apparatus calibration and standardization procedures for various inspection methods. The
evaluation of imperfections and marking of inspected OCTG are included.
This International Standard is applicable to field inspection of OCTG and is not applicable for use as a basis
for acceptance or rejection (for which the relevant purchasing specification is applicable, see 5.4.2).
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 may lead to technical results different
from the use of the preceding ISO reference. However, both results are acceptable and these documents are
thus considered interchangeable in practice.
NOTE ISO 11960 has been back-adopted by API as API Spec 5CT. Therefore, for the purposes of the provisions in
this International Standard which cite ISO 11960, API Spec 5CT is equivalent to ISO 11960.
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 specific field inspection and testing, it is intended that only one
unit system be used, without combining data expressed in the other system.
Inspection and testing performed using either of these unit systems shall be considered equivalent and totally
interchangeable. Consequently, compliance with the requirements of the relevant Product Standard
expressed in one of the unit systems provides compliance with the 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 A and Annex C, respectively.
For a specific order item, only one unit system shall be used.
In this International Standard, cross-references are made only to the tables in Annex A; if the USC units apply
on an order, then any cross-references to tables in Annex A shall be taken to mean the equivalent table in
Annex C.
Figures (data expressed in both SI and USC units) are contained in Annex B.
3 Normative references

references, only the edition cited applies. For undated references, the latest edition of the referenced
