Foreword
ISO (the International Organization for Standardization) is a worldwide fed-
eration 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 rep-
resented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO col-
laborates closely with the International Electrotechnical Commission (IEC)
on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are cir-
culated 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 14284 was prepared by Technical Committee
lSO/TC 17, Steel, Subcommittee SC 1, Methods of determination of
Chemical composition.
lt cancels and replaces ISO 377-2:1989, of which it constitutes a technical
revision.
Annexes A and B of this International Standard are for information only.
