General methods of test for pigments and extenders - Part 23 : Determination of density (using a centrifuge to remove entrained air)

Document Preview

Displacement liquids of known density should be selected in which the material to be tested is insoluble, and which has good wetting properties and a low evaporation rate under vacuum. High-boiling aromatic or aliphatic hydrocarbons are suitable. The temperature, t, at which the determination is carried out affects the density of the displacement liquid; each weighing should be made at a constant temperature. The principle consists in weighing into a tared tube a quantity of a dried sample, wetting it with displacement liquid, centrifuging until the occluded air is removed and calculation of the density from the difference of masses.
