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
(IEC) 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 10432 was prepared by the American Petro-
leum Institute (API) (as Spec 14A, 8th edition) and was adopted, under a
special “fast-track procedure”, by Technical Committee ISO/TC 67, Mate-
rials, equipment and offshore structures for petroleum and natural gas in-
dustries, in parallel with its approval by the IS0 member bodies.

Introduction
International Standard IS0 10432:1993 reproduces the content of
API Spec 14A, 8th edition, 1994. ISO, in endorsing this API document,
recognizes that in certain respects the latter does 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 ‘lO432:1993 and reissue it, when practicable, in a form com-
plying 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.
Appendices A, B and C form an integral part of this standard.

1 Scope
This International Standard provides the minimum acceptable requirements for subsurface safety valve equipment,
and all components that establish tolerances and/or clearances which may affect performance or interchangeability
of such equipment.
2 Requirements
Requirements are specified in:
“API Specification 14A (Spec 14A), Eighth Edition, January 1, 1994- Specification for Subsurface Safety Valve
Equipment”,
which is adopted as IS0 10432.
I apply to specific clauses and para-

STRENGTH OR STRESS 1 pound-force per square inch Ibf/in*) = 6,894757 Pa
IMPACT ENERGY 1 foot-pound force (ftlbf) = I,355818 J
TORQUE 1 foot-pound force (ftlbf)
= I,355818 N.m
TEMPERATURE The following formula was used to convert degrees Fahrenheit (OF) to degrees
Celsius (“0
“C = 519 (“F - 32)
MASS ‘I pound (lb) = 0,453 592 37 kg (exactly)
VOLUME 1 cubic foot (ft3) = 0,02831685 m3
or 28,31685 dm3
