ISO 3233-3:2015 a simple practical method for calculating the non-volatile matter by volume, NVV, of a coating material from the non-volatile-matter content, NV, the density of the coating material, and the density of the solvents. Using the non-volatile matter by volume results and the density obtained in accordance with this part of ISO 3233, it is possible to calculate the theoretical spreading rate of a coating material.
ISO 3233-3:2015 is not applicable to coating materials which exceed the critical pigment volume concentration (CPVC).
