Foreword
Standardization) is a worldwide fed-
IS0 (the International Organization for
eration of national standards bodies IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each membe body interested in a subject for
which a technical committee has beet 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. IS0 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 IS0 13543 was prepared by Technical Committee
ISO/TC 183, Copper, lead and zinc ores and concentrates.
