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 represented 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 10422 was prepared by the American Petroleum Institute
(API) (as STD 5B, 13th ed.) and was adopted, under a special “fast-track procedure”,
by Technical Committee lSO/TC 67, Materiak and equipment for petroleum and
natural gas industries, in parallel with its approval by the IS0 member bodies.

Introduction
International Standard IS0 10422:1993 reproduces the content of API STD 5B, 13th
edition, 1988. 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
ISOFC 67, will review IS0 10422:1993 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 can be shown to meet or exceed the requirements of the referenced
standards.
Appendix A t :o this documen t should not be considered as requirements. It is
included only as guidelines.
