Determination of particle size distribution by centrifugal liquid sedimentation methods - Part 1: General principles and guidelines

Sets out methods for determining the particle size distributions of particulate materials, typically in the size range 0.1 µm to 5 µm, by centrifugal sedimentation in a liquid. The methods of determining the particle size distribution described in this part of ISO 13318 are applicable to slurries, particulate materials which can be dispersed in liquids and some emulsions. A positive density difference between the discrete and continuous phases is necessary, although centrifugal photosedimentation can be used for emulsions where the droplets are less dense than the liquid in which they are dispersed. This Standard is identical with and has been reproduced from ISO 13318-1:2001.
