标准范围

ISO 3251:2008规定了一种按涂料、清漆、涂料和清漆用粘合剂、聚合物分散体和缩合树脂（如酚醛树脂（酚醛树脂、酚醛树脂溶液等）质量测定非挥发性物质含量的方法。该方法也适用于含有填料、颜料和其他助剂（例如增稠剂和成膜剂）的配方分散液。对于可用于未增塑聚合物分散体和橡胶胶乳的方法，非挥发性残留物（主要由聚合物材料和少量助剂组成，如乳化剂、保护胶体、稳定剂、作为薄膜添加的溶剂）-成型剂（尤其是胶乳浓缩物的保护剂）在试验条件下必须具有化学稳定性。对于增塑样品，根据定义，残留物通常包括增塑剂。

ISO 3251:2008 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 residue, by definition, normally includes the plasticizer.
