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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

This document was prepared by Technical Committee ISO/TC 256, Pigments, dyestuffs and extenders , in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 298, Pigments and extenders, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 3262-17:2000), which has been technically revised.

The main changes are as follows:

• the first part of the title has been changed to"Extenders";
• ISO 19246 has been added as an alternative test method for oil absorption value in Table 1;
• ISO 13320 has been added as test method for particle size distribution in Table 2;
• DIN 53163 has been added as test method for lightness (tristimulus value Y) in Table 2;
• CAS-numbers have been added to all reagents used for the test methods specified;
• the normative references have been updated.

A list of all parts in the ISO 3262 series can be found on the ISO website.
