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 2.

The main task of technical committees is to prepare International Standards. 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.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 1524 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes.

This fourth edition cancels and replaces the third edition (ISO 1524:2000), which has been technically revised. The main changes are as follows:

a) products containing pigments in flake form (e.g. glass flakes, micaceous iron oxides, zinc flakes) have been excluded from the scope;
b) Figure 1 has been revised to show two examples of a typical gauge rather than one, and corrected to show the gauge scale in micrometres instead of millimetres;
c) Figures 3 and 4 have been replaced by a new figure which indicates more clearly the reading on the gauge.
