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 10424-1 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.
ISO 10424 consists of the following parts, under the general title Petroleum and natural gas industries —
Rotary drilling equipment:
 Part 1: Rotary drill stem elements
 Part 2: Threading and gauging of rotary shouldered thread connections

ISO 10424-1:2004(E)
Introduction
The function of this part of ISO 10424 is to define the design and the mechanical properties of the material
required for rotary drill stem elements. It also defines the testing required to verify compliance with these
requirements. As rotary drill stem elements are very mobile, moving from rig to rig, design control is an
important element required to ensure the interchangeability and performance of product manufactured by
different sources.
A major portion of this part of ISO 10424 is based upon API Spec 7, 40th edition, November 2001. However,
API Spec 7 does not define the nondestructive testing requirements of materials used to manufacture the drill
stem components covered by this part of ISO 10424. This part of ISO 10424 does address these
requirements.
Users of this part of ISO 10424 should be aware that further or differing requirements may be needed for
individual applications. This part of ISO 10424 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 part of ISO 10424 and provide details.
In this part of ISO 10424, certain ISO and non-ISO standards provide the same technical result for a particular
provision, however there is a market need to retain the traditional non-ISO reference.
In the running text the provision is written in the form “……… in accordance with ISO xxx.
NOTE For the purposes of this provision, non-ISO Ref yyy is equivalent to ISO xxx.”
Application of a non-ISO reference 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. In recognition of
the migration of global standardization towards the use of ISO standards, it is intended that references to
these alternative documents be removed at the time of the first full revision of this part of ISO 10424.

2.1 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 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 is used as the decimal separator and a space as the
thousands separator.
Data within the text of this International Standard are expressed in SI units followed by data in USC units in
parentheses.
2.2 Tables and figures
Separate tables for data expressed in SI units and in USC units are given. The tables containing data in SI
units are included in the text and the tables containing data in USC units are given in Annex A. For a specific
order item, only one unit system shall be used.
Figures are contained in the text of the clause concerning the particular product, and express data in both SI
and USC units.
