AS 4549.1-1999

Sets out the application of photon correlation spectroscopy (PCS) to the measurement of an average particle size and a measure of the broadness of the size distribution of particles dispersed in liquids. It is applicable to particle sizes ranging from a few nanometers to about 1 µ, or to the onset of sedimention. This Standard is identical with and has been reproduced from ISO 13321:1996.
