This part of ISO 2811 specifies a method for determining the density of paints, varnishes and related products using a metal or Gay-Lussac pyknometer.The method is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pyknometer (see ISO 3507) can be used for highly viscous materials.
