This part of ISO 787 specifies a general method of test for determining the residue of sieve from a sample of pigment or extender dispersed in water.
Part 18 of ISO 787 specifies a general method of test for determining the residue on sieve from a samply of pigment or extendr by a mechanical flushing procedure. For most pigments and extenders, these two methods will usually 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.
