D100 Separation

Definition(s)


D100 Separation

Particle size, expressed in micrometres, determined by plotting the percentage of aluminium oxide (aluminum oxide) sample separated by the test screen on the plot of cumulative mass fraction (as percent) retained versus U.S. Sieve Opening (expressed in micrometres) for the sieve analysis of the aluminium oxide test sample. NOTE 100 % of the particles larger than the D100 separation are retained by the test screen.
