What do D 10, D50 and D90 in particle size distribution mean? I have the test report. What do you mean by writing granularity D 10=0.45?

D 10, D50 and D90 indicate that the particle (including weight) content calculated according to the maximum particle size is 10%, 50% and 90% respectively. D 10=0.45 in your inspection report means that the content of these particles is 10% from the coarsest particle to 0.45um. I understand it this way, and I hope it will help you.
