DANSK DS/ISO 3233-1 PDF

This document specifies a method for determining the non-volatile matter by volume (NVV) 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. Using the non-volatile matter by volume results obtained in accordance with this part of ISO 3233, it is possible to calculate the spreading rate of coating materials. The method specified in this document is the preferred method for air-drying materials. Its use for other materials still has to be tested. Annex B gives an overview of the existing methods for determination of non-volatile-matter content and volume of non-volatile matter. This document is not applicable to coating materials in which the critical pigment volume concentration is exceeded.
