Foreword ISO (the International Organization for Standardization) is a worldwide federation of
17、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. Inte
18、rnational 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 th
19、e 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. Attention is drawn to th

Such constituents, which could make up about 10 % of the pigment, will be lost during ashing. As the state of many pigments and extender
24、s changes under the specified test conditions, it will depend on the composition and the chosen ashing temperature whether the actual pigment content of the product under test can be deduced from the apparent pigment content found by this method. The method is generally not suitable for UV paints an
