scope:

This International Standard specifies 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 International Standard, it is possible to calculate the theoretical spreading rate of a coating material. This International Standard is not applicable to coating materials which exceed the critical pigment volume concentration (CPVC).
