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. 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. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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 3262-8 was prepared by Technical Committee ISO/TC 35, Paints and varnishes,
Subcommittee SC 2, Pigments and extenders.
Together with the other parts (see below), this part of ISO 3262 cancels and replaces ISO 3262:1975, which has
been technically revised. Part 1 comprises the definition of the term extender and a number of test methods that are
applicable to most extenders, whilst part 2 and the following parts specify requirements and, where appropriate,
particular test methods for individual extenders.
At present, the following parts of ISO 3262 are published or in preparation, under the general title Extenders for
paints — Specifications and methods of test:
Part 1: Introduction and general test methods
Part 2: Barytes (natural barium sulfate)
Part 3: Blanc fixe
Part 4: Whiting
Part 5: Natural crystalline calcium carbonate
Part 6: Precipitated calcium carbonate
Part 7: Dolomite
Part 8: Natural clay
Part 9: Calcined clay
Part 10: Natural talc/chlorite in lamellar form
Part 11: Natural talc, in lamellar form, containing carbonates
Part 12: Muscovite-type mica
Part 13: Natural quartz (ground)
Part 14: Cristobalite
Part 15: Vitreous silica
