Paints and varnishes — Determination of percentage volume of non-volatile matter by measuring the non-volatile matter content and the density of the coating material, and calculation of the theoretical spreading rate ISO 23811:2009

Publication date:   Feb 9, 2009

Scope

ISO 23811:2009 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 ISO 23811:2009, it is possible to calculate the theoretical spreading rate of a coating material.
ISO 23811:2009 is not applicable to coating materials which exceed the critical pigment volume concentration (CPVC).
