Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for
which a technical committee has been established has the right to be re-
presented on that committee. International organizations, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(I EC) on all matters of electrotechnical standardization.
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.
International Standard IS0 10428 was prepared by the American Petro-
leum Institute (API) (as Spec 11 B, 24th edition) and was adopted, under
a special “fast-track procedure”, by Technical Committee ISO/TC 67, Ma-
terials, equipment and offshore structures for petroleum and natural gas
industries, in parallel with its approval by the IS0 member bodies.

Introduction
International Standard IS0 10428:1993 reproduces the content of
API Spec 11 B, 24th edition, 1990, and its Supplement 1 (April 1, 1991).
ISO, in endorsing these API documents, recognizes that in certain re-
spects they do not comply with all current IS0 rules on the presentation
and content of an International Standard. Therefore, the relevant technical
body, within lSO/TC 67, will review IS0 10428:1993 and reissue it, when
practicable, in a form complying with these rules.
This standard is not intended to obviate the need for sound engineering
judgement as to when and where this standard should be utilized and
users of this standard should be aware that additional or differing require-
ments may be needed to meet the needs for the particular service in-
tended.
Standards referenced herein may be replaced by other international or
national standards that can be shown to meet or exceed the requirements
of the referenced standards.
Appendix A to the API document shall not be regarded as being part of the
requirements of this standard.

INTERNATIONAL STANDARD 0 IS0 IS0 10428:1993(E)
Petroleum and natural gas industries - Sucker rods
(pony rods, polished rods, couplings and
sub-couplings) - Specification
1 Scope
This International Standard specifies the requirements for the dimensional characteristics, chemical and mechan-
ical properties and gauging practice of sucker rods (pony rods, polished rods, couplings and sub-couplings) used
in the petroleum and natural gas industries.
2 Requirements
Requirements are specified in:
“API Specification 11 B (Spec 11 B), Twenty-forth Edition, October 1, 1990
- Specification for Sucker Rods
(Pony Rods, Polished Rods, Couplings and Subcouplings)“,
which is adopted as IS0 10428.
For the purposes of international standardization, however, modifications shall apply to specific clauses and para-
graphs of publication API Spec 11 B. These modifications are outlined below.
Throughout publication API Spec 11 B, the conversion of English units shall be made in accordance with IS0 31.
LENGTH 1 inch (in) = 25,4 mm (exactly)
1 foot (ft) = 304,8 mm or 0,3048 m (exactly)
TORQUE 1 foot-pound force (ftlbf) = 1,355818 N#m
TEMPERATURE The following formula was used to convert degrees Fahrenheit (OF) to degrees
Celsius (“C)
“C = 519 (“F - 32)

Section 8, Gauge certification
The gauge certification system specified in this section is not considered as an integral part of this International
Standard. This system shall be subject of a further study by lSO/TC 67 with a view to establishing an IS0 or
lSO/APl certification scheme. The registration of certification agencies and reference master gauges should then
be carried out in accordance with Annex N of Part 1 of the ISO/lEC Directives.
