Background

This standard specifies the method for the determination of non-volatile matter content of paints, varnishes, binders for paints and varnishes, polymer dispersions and condensation resins, such as phenolic resin (resols, novolak solutions, etc.).

This method is also applicable to dispersions containing pigments, fillers and other auxiliaries (such as thickeners and film-forming agents). This standard can also be used for unplasticized polymer dispersions and rubber latices, the non-volatile residue (mainly polymeric material and a small amount of auxiliaries such as emulsifiers, protective colloids, stabilizers, film-forming agents added as solvents, in particular preservatives for the concentrated rubber latex) under the test conditions should be chemically stable. For plasticized samples, non-volatile residue typically includes plasticizers.
