标准摘要
[中文适用范围]： 本文件规定了通过测定实际干膜密度来测定涂料材料的不挥发物体积（NVV）的方法。 该方法通过测量任何指定温度范围和干燥或固化时间的干涂层的密度来确定油漆、清漆和相关产品中不挥发物的体积百分比。 不挥发物含量根据ISO 3251测定。 使用根据该文件获得的不挥发物体积结果，可以计算涂料材料的实际铺展率。 该方法规定了 ISO 3233-1 中描述的板的附加形状，并且适用于所有可以通过浸渍施加的产品。 本文件不适用于超过临界颜料体积浓度（CPVC）的涂料材料。 附件 A 概述了测定不挥发物含量和不挥发物体积的现有方法。 [外文原描述]： This document specifies a method for determining the non-volatile matter by volume (NV V ) of coating materials by determining the practical dry-film density. This method determines the volume percentage of non-volatile matter in paints, varnishes and related products by measuring the density of a dry coating for any specified temperature range and period of drying or curing. The non-volatile matter content is determined in accordance with ISO 3251. Using the non-volatile matter by volume results obtained in accordance with this document, it is possible to calculate the practical spreading rate of coating materials. This method specifies an additional shape of plate to those described in ISO 3233‑1 and is suitable for all products which can be applied by dipping. This document is not applicable to coating materials which exceed the Critical Pigment Volume Concentration (CPVC). Annex A gives an overview of the existing methods for the determination of non-volatile matter content and of non-volatile matter volume.
