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 10419 was prepared by the American Petroleum Institute
(API) (as RP 14H, 3rd edition) and was adopted, under a special “fast-track procedure ”,
by Technical Committee lSO/TC 67, Materiak and equipment for Petroleum and
natura/ gas industries, in parallel with its approval by the ISO member bodies.

Introduction
International Standard ISO 10419:1993 reproduces the content of API RP 14H, 3rd
edition, 1991. ISO, in endorsing this API document, recognizes 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 10419:1993 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 tan be shown to meet or exceed the requirements of the referenced
Standards.
