Paints and varnishes — Determination of the percentage volume of non-volatile matter — Part 2: Method using the determination of non-volatile-matter content in accordance with ISO 3251 and determination of dry film density on coated test panels by the Archimedes principle
ISO 3233-2:2014 specifies a method for determining the non-volatile matter by volume (NVv) 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.
Using the non-volatile matter by volume results obtained in accordance with ISO 3233-2:2014, 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.
