The measuring results of particle size distributions obtained by various equipments do not always agree, even if the same sample is measured. To clarify the agreement for each measuring principle, the results obtained by optimized and standardized sample preparation condition should be compared systematically. In this study, silicon carbide and silicon nitride as submicron non-oxide powder and boron nitride having flaky shape were used as common samples, and the agreement of measuring principles was investigated for each sample. The following results were obtained. (1)in the measurement of submicron powders, the position of the scatter of the distributions measured by different principle changes depending on the size distribution of the primary particle and the strength of the agglomerate. The scatter of the equipments is more remarkable than micron powders. (2)in the measurement of flaky shape samples, the effect of the shape on measured results can be explained by considering the orientation of the particles in the suspension.
