1 Scope This standard specifies a method for determining the non-volatile-matter content by mass of paints, varnishes, binders for paints and varnishes, polymer dispersions and condensation resins such as phenolic resins (resols, novolak solutions, etc.). The method is also applicable to formulated dispersions containing fillers, pigments and other auxiliaries (e.g. thickeners and film-forming agents). For the method to be usable for unplasticized polymer dispersions and rubber latices, the non-volatile residue (which consists essentially of the polymeric material and of small quantities of auxiliaries such as emulsifiers, protective colloids, stabilizers, solvents added as film-forming agents and - especially for rubber latex concentrate - preserving agents) has to be chemically stable under the test conditions. For plasticized samples, the non-volatile residue normally includes the plasticizer. NOTE 1: The non-volatile-matter content of a sample is not an absolute quantity but depends upon the temperature and period of heating used for the determination. Consequently, when using this method, only relative and not true values of the non-volatile-matter content are obtained owing to solvent retention, thermal decomposition and evaporation of low-molecular-mass constituents. The method is therefore primarily intended for testing different batches of the same type of product. NOTE 2: This method is suitable for synthetic rubber latices provided heating for a specific period of time is considered appropriate (ISO 124 specifies heating until the loss in mass of a 2g test portion following successive periods of heating is less than 0.5mg). NOTE 3: The methods for determining non-volatile matter often include drying with infrared or microwave radiation. Standardization of such methods is not possible, since they are not generally applicable. Some polymer compositions tend to decompose during such treatment and therefore give incorrect results. “Paints and Varnishes - Determination of Percentage Volume of Non-volatile Matter by Measuring the Density of a Dried Coating (ISO 3233:1998)” specifies a method for determining the volume of non-volatile matter in paints, varnishes and related products. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard.
