As adopted by the Council Madrid, Spain, on 9 September 1975
Incorporating additions and amendments approved
S1 Definition of the Union
- The International Union of Pure and Applied Chemistry (IUPAC) (hereafter
referred to as "the Union") is a voluntary, nongovernmental,
nonprofit association of organizations each representing the chemists
of a member country, a member country being a country whose Adhering
Organization has joined the Union.
- The objectives of the Union are:
- S2.1 to promote continuing cooperation among the chemists
of the member countries;
- S2.2 to study topics of international importance to pure
and applied chemistry which need standardization or codification;
- S2.3 to cooperate with other international organizations
which deal with topics of a chemical nature;
- S2.4 to contribute to the advancement and understanding of
pure and applied chemistry in all its aspects.
- S2.5 In pursuing these objectives the Union will observe
the basic policy of political nondiscrimination and affirms the rights
of chemists of any country to adhere to or to associate with international
activity in the field of chemistry without regard to race, religion,
or political philosophy.
- S3.1 A country may join the Union through only one national
organization representing its chemists. This Adhering Organization
may be a national chemical council, a national society representing
chemistry, a national academy of science, or any other institution
or association of institutions representative of national chemical
- S3.2 The Adhering Organizations are the Members of the Union.
- S3.3 A country requesting admission to the Union shall provide
full information about its proposed Adhering Organization.
- S3.4 An Adhering Organization may withdraw from the Union
provided that it has fulfilled its financial obligations, or may be
removed from the Union for failure to fulfill such obligations.
- S4.1 The organization of the Union comprises its Council,
a Bureau, an Executive Committee, Standing Committees, Divisions,
Sections, Commissions, and other appropriate bodies as determined
by the Council.
- S4.2 A General Assembly of the International Union of Pure
and Applied Chemistry shall be held normally each second year, beginning
with 1963, and shall consist of a set of meetings of the Council and
such other bodies of the Union as the Bureau shall decide. Where the
duration of office of Officers of the Union, Elected Members of the
Bureau, and Titular Members and Associate Members of Division and
Section Committees, Commissions, or other bodies of the Union is referred
to in these Statutes, it shall begin on 1 January of the year following
their election at a General Assembly and shall end on 31 December
of the year when the appointment is due to terminate. In the filling
of casual vacancies the Bureau may authorize an appointment to Division
and Section Committees, Commissions, and other bodies of the Union
except for the Executive Committee and Bureau to begin at an intermediate
date. Any such appointment should be regarded as dating from 1 January
of the year following the previous General Assembly in respect of
the period of office for Division and Section Committees, and Commissions.
No person shall hold more than three appointments to bodies of the
Union, except at the discretion of the Bureau in respect of membership
of a subcommittee or acting as an official representative within or
outside the Union.

- S5.32 For all voting by the Council abstentions shall not
be recorded as votes.
- S5.33 The voting procedure to be adopted is different according
to whether a proposal is a scientific or nonscientific matter. The
Presiding Officer shall decide whether for the purpose of voting a
matter shall be considered to be of a scientific or nonscientific
nature and that decision shall be final. The method of voting shall

or any Adhering Organization. Notice of changes so proposed shall
reach the Secretary General at the Secretariat in writing at least
ten months before the meeting of the Council at which the proposal
is to be considered. No change shall be made except at a meeting of
the Council and with the approval of two-thirds of the total number
of votes assigned to the Adhering Organizations.
- S14.4 In all cases where the Statutes are not clear or do
not give a decision, the President's ruling shall be decisive.
- The Union shall not be dissolved except at a meting of the Council
convened specifically for this purpose by notice given three months
in advance. At such a meeting, more than three- quarters of the maximum
possible number of votes of the Adhering Organizations must be represented
and cast, and two-thirds of the votes recorded shall be required for
dissolution. If three-quarters of the maximum possible number of votes
are not represented, the Council shall be convened again after a period
of at least six months and at this second meeting the Union may be
dissolved if the proposal for dissolution receives two-thirds of the
votes recorded. In the case of dissolution of the Union, the Council
