適用范圍：1 This part of ISO 787 specifies a general method for de-termining the residue on a sieve from a sample of pigment or extender dispersed in water, using a mechanical flushing procedure. This method can also be applied to the examination of other powders or granules which are insoluble in water. It is neither applicable to hydrophobic nor pelletized pigments and extenders. 2 ISO 787/7 specifies a general method of test for de-termining the residue on a sieve from a sample of pigment or extender dispersed in water, using a manual procedure. 3 For most pigments and extenders, these two test methods will give different results, and it is therefore essential to state clearly in a specification which method is to be used, and in the test report, which method has been used. NOTE ?When either of these general methods is applicable to a given pigment or extender, only a cross-reference to it should be inducted in the International Standard relating to that pigment or extender, with a note of any detailed modification which may be needed in view of the special properties of the material under consideration. Only when neither of these general methods is applicable to a particular material a special method for determination of residue on sieve should be specified.
