UNE EN ISO 3233-2:2020
This part of ISO 3233 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 this part of ISO 3233, 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 part of ISO 3233 is not applicable to coating materials which exceed the critical pigment volume concentration (CPVC).
