Describes a method for determination of the sieve residue of polymer dispersions by sieve analysis. Only applicable to coagulum-type content.

This International Standard 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 of closely related dispersions.

This International Standard refers only to coagulum-type content. Skinned material and fragments of skin larger than 5 mm are avoided while taking the sample (see clause 6)
