Determination of particle size distribution by gravitational liquid sedimentation methods General principles and guidelines
Standards Australia
Sets out methods for determining the particle size of particulate materials, typically in the size range 0.5 to 100 µm, by gravitational sedimentation in a liquid. This Standard is identical with and has been reproduced from ISO 13317-1:2001.

This part of ISO 13317 covers methods for determining the particle size distributions of particulate materials, typically in the size range 0,5 m to 100 m, by gravitational sedimentation in a liquid.
NOTE: This part of ISO 13317 may involve hazardous materials, operations and equipment. This part of ISO 13317 does not purport to address all the safety problems associated with its use. It is the responsibility of the user of this part of ISO 13317 to establish appropriate safety and health practices and to determine the applicability of the regulatory limitations prior to its use.
The methods of determining the particle size distribution described in this part of ISO 13317 are applicable to slurries or to particulate materials which can be dispersed in liquids. A positive density difference between the discrete and continuous phases is necessary, although gravitational photosedimentation can be used for emulsions where the droplets are less dense than the liquid in which they are dispersed. Particles should not undergo any physical or chemical change in the suspending liquid. The usual precautions need to be taken with hazardous material, and explosion proof analysers are required when examining volatile liquids with a low flash point.
