3、on for Standardization) is a worldwide federation of national standards institutes (IS0 member bodies). The work of developing Interna- tional Standards is carried out through IS0 technical committees. Every member body interested in a subject for which a technical committee has been set up has the
4、right to be represented on that committee. International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as I
5、nternational Standards by the IS0 Council. International Standard IS0 787/22 was developed by Technical Committee ISO/TC 35, Paints and varnishes, and was circulated to the member bodies in March 1978. It has been approved by the member bodies of the following countries : Australia Austria Bulgaria

8、IHS -,-,- The purpose of this International Standard is to establish a series of general test methods for pigments and extenders which are suitable for all or many of the individual pigments and extenders for which specifications might be required. In such cases, a cross-reference to the general met
9、hod should be included in the International Standard relating to that pigment or extender, with a note of any detailed modifications which might be needed in view of the special properties of the product in question. Technical Committee ISO/TC 35 decided that all the general methods should be publis
10、hed as they become available, as parts of a single International Standard, in order to emphasize the relationship of each to the whole series. The Technical Committee also decided that, where two or more procedures were widely used for determining the same or a similar characteristic of a pigment or
11、 ex- tender, there would be no objection to including more than one of them in the IS0 series. In such cases it will, however, be essential to state clearly in a specification which method is to be used and, in the test report, which method has been used. Parts of the series already published are as
12、 follows : Part 1 : Comparison of colour Part 2 : Determination of matter volatile at 105 OC Part 3 : Determination of matter soluble in water - Hot extraction method Part 4 : Determination of acidity or alkalinity of the aqueous extract Part 5 : Determination of oil absorption value Part 6 : Determ

14、etermination of tamped volume and apparent density after tamping Part 12 : Visual comparison of hue of powdered white pigment (Hollow cone methodll) Part 13 : Determination of water-soluble sulphates, chlorides and nitrates Part 14 : Determination of resistivity of aqueous extract Part 15 : Comparis
