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. Esch 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.
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 ISO 10433 was prepared by the American Pet-
roleum Institute (API) (as Spec 14D, 9th edition) and was adopted, under
a special “fast-track procedure ”, by Technical Committee lSO/TC 67, Ma-
terials, equipment and offshore structures for Petroleum and natura1 gas
industries, in parallel with its approval by the ISO member bodies.

Introduction
International Standard ISO 10433:1994 reproduces the content of API
Spec 14D, 9th edition, 1994. ISO, in endorsing this API document, recog-
nizes that in certain respects the latter does not comply with all current
ISO rules on the presentation and content of an International Standard.
Therefore, the relevant technical body, within ISO/TC 67, will review
ISO 10433:1994 and reissue it, when practicable, in a form complying with
these rules.
This International Standard is not intended to obviate the need for Sound
engineering judgement as to when and where this International Standard
should be utilized and users should be aware that additional or differing
requirements may be needed to meet the needs for the particular Service
intended.
Standards referenced herein may be replaced by other international or
national Standards that tan be shown to meet or exceed the requirements
of the referenced Standards.
Appendix D to this document shall not be considered as requirements.

This International Standard lays down the specification for wellhead surface protective valves and undewvater
protective valves used as means of ensuring weil stream shutoff.
2 Requirements
Requirements are specified in: -
“API Specification 140 (Spec 14D), Ninth Edition, June 1 1994 - Specification for Wellhead Surface Safety
Valves and Underwater Safety Valves for Offshore Service ”,
which is adopted as ISO 10433.
For the purposes of international standardization, however, modifications shall apply to specific clauses and para-
graphs of publication API Spec 14D. These modifications are outlined below.
