DIN ISO 4576:2001-03

The document specifies a method of determining the sieve residue (gross particle and coagulum content) of polymer dispersions, i.e. of particles much greater in diameter (for example 10 or 100 times) than the mean diameter of the other particles. This determination is carried out by sieve analysis. The sieves used depend on the type of dispersion under test and are in consequence to be specified or agreed upon by the interested parties, for each dispersion or group closely related dispersion.
