Scope: This standard specifies the method for measuring the average particle size and particle size distribution of submicron-nano particles or droplets dispersed in a liquid by using the dynamic light scattering method (DLS). This standard is applicable to a wide range of concentrations and can be measured from lower For suspensions with higher concentration, for low concentration suspension samples, the dynamic light scattering method is the same as photon correlation spectroscopy; for high concentration suspension samples, in addition to the correct interpretation of the test results, the measurement device, sample preparation, etc. and other specific requirements,
