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
(1 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 ISO 10423 was prepared by the American Pet-
roleum Institute (API) (as Spec 6A, 16th 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 natura/ gas
industries, in parallel with its approval by the ISO member bodies.

Introduction
International Standard ISO 10423:1994 reproduces the content of API
Spec 6A, 16th edition, 1989. 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 lSO/TC 67, will review
ISO 10423:1994 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 of this Standard should be aware that addi-
tional 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.
Appendices A, C, D, E and H to this document should not be considered
as requirements. They are included only as guidelines or information.

1 Scope
This International Standard provides for the availability of Safe, dimensionally and functionally interchangeable
wellhead and christmas tree equipment by laying down the requirements for Performance, design, materials,
testing, inspections, welding, marking, handling, storing and shipping.
2 Requirements
Requirements are specified in:
“API Specification 6A (Spec 6A), 16th edition, October 1, 1989 - Specifica tion for Wellhead and Chris tmas
Tree Equipmen t” ,
adopted as ISO 10423.
For the purposes of international standardization, however, modifications shall apply to specific clauses and para-
graphs of publication API Spec 6A. These modifications are outlined below.

Metric conversions
Throughout publication API Spec 6A and its Supplement 1, the conversion of English units shall be made in ac-
cordante with ISO 31. The content shall be replaced by the following.
LENGTH 1 inch (in) = 25,4 mm (exactly)
1 foot (ft) = 304,8 mm
PRESSURE 1 pound-forte per Square inch (Ibf/in2)
= 6894,757 Pa
or psi
NOTE 1 bar = IO5 Pa
STRENGTH OR STRESS 1 pound-forte per Square inch (Ibf/in2) = 6894,757 Pa
IMPACT ENERGY 1 foot-pound forte (ftlbf) = 1,355818 J
1 foot-pound forte (ftlbf) = 1,355818 N.m
TORQUE
TEMPERATURE The following formula was used to convert degrees Fahrenheit (“F) to degrees
Celsius (“C):
“C = 519 (OF - nnJL) ’
VOLUME 1 cubic foot = 0,0283168 m3 or 28,3168 dm3
MASS 1 pound (Ib) = 0,453 592 37 kg (exactly)
