Over deze norm
The standard addresses the determination of density of solid particles or liquid droplets (below named generalized particle) dispersed in a liquid. It is based on the reason that a particle wholly immersed in fluid experiences buoyancy equal to the weight of the fluid displaced by this particle (Archimedean principle), and it stays suspended as its mass force matches the buoyancy force. This implies that density of the particle equals the density of the liquid. According to this standard particle density determination is conducted by analysing the direction of migration movement of particles dispersed in liquids with lower and higher densities as the particle density. All particles shall be of the same materials composition.
