<p>This document specifies a method for determining the non-volatile matter by volume (NV<sub>V</sub>) of coating materials and related products by measuring the density of a dried coating for any specified temperature range and period of drying or curing. This method determines the non-volatile matter immediately after application.</p>
<p>Using the non-volatile matter by volume results obtained in accordance with this document, it is possible to calculate the spreading rate of coating materials.</p>
<p>The method specified in this document is the preferred method for air-drying materials. Its use for other materials has not yet been tested.</p>
<p>Annex B gives an overview of the existing methods for determination of non-volatile-matter content and volume of non-volatile matter.</p>
<p>This document is not applicable to coating materials in which the critical pigment volume concentration is exceeded.</p>
