The work of preparing International Standards is no
19、rmally 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
20、 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 t
21、he different approval criteria needed for the different types of ISO documents 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).Attention is drawn to the possibility that some of the elements of this docu

25、first edition (ISO 13803:2000), which has been technically revised. The main technical changes are:a) the symbols have been adapted to the revision of ISO 2813;b) an introduction and a principle clause have been added;c) the supplementary test conditions have been included in the test report;d) the

Microstructures can cause a milky appearance. This effect is described as haze. A high gloss surface wit
27、h microscopic texture has diffused light with low intensity adjacent to the main direction of reflection. The majority of the incident light is reflected in the specular direction which will make the surface appear high glossy with image forming qualities, but with a milky haziness on top of it.The
28、phenomenon haze can be seen on high gloss surfaces only. Therefore, the 20 geometry is used like with a gloss meter. The aperture range of a 20 gloss meter is 1,8. Two additional sensors next to the gloss detector measure the intensity of the diffused light responsible for haze. Thus, the specularly
29、 reflected and the scattered light are measured simultaneously. In order to better correlate with the visual perception, haze is displayed in a logarithmic scale the lower the haze reading the better the surface.

30、hes Determination of haze on paint films at 201 ScopeThis International Standard specifies a test method for determining the haze of coatings. The method is suitable for the haze measurement of non-textures coatings on plane, opaque substrates.The use of the 20 geometry means that the method is clos
31、ely related to the measurement of gloss at 20 in ISO 2813. The application of this method is intended to give improved differentiation between high-gloss surfaces, for example in the field of assessment of dispersion characteristics.2 Normative referencesThe following documents, in whole or in part,
