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 3262-9 was prepared by Technical Committee
ISO/TC 35, Paints and varnishes, Subcommittee SC 2, Pigments and extenders.
Together with the subsequent parts, this International Standard cancels and
replaces IS0 3262: 1975 which has been technically revised and divided into
parts. Part 1 comprises the definition for the term extender and a number of test
methods that are applicable to most extenders, whilst parts 2 and the following
specify requirements and, where appropriate, particular test methods for individual
extenders.
At present, the following parts of IS0 3262 are in preparation, under the general
title

3 Definition
For the purposes of this part of IS0 3262, the following definition applies:
3.1 calcined clay: Aluminium silicate (AI,O, l 2SiO,), lamellar, mainly amorphous
in structure as determined by X-ray diffraction, produced from natural clay by
thermal dehydration,, consisting partly of crystalline mullite (3AI,O, l 2Si0,) l
4 Requirements and test methods
For calcined clay complying with this part of IS0 3262, the essential requirements
are specified in table 1 and the conditional requirements are listed in table 2.

is given as the referee method. Other methods may, however, be used by
agreement between the interested parties, but in such cases it will be necessary
to agree on appropriate limits.
6.1 Principle
The rate of fal of spherical particles through a medium in which they are dispersed
is proportiona to the square of the particle diameter (Stokes’ law). The Andreasen
method for de :ermination of particle size distribution makes use of this relationship
