Particle size distribution :: Anton Paar Wiki

Kurtosis: Measure of the deviation from the normal (Gaussian) distribution or in other words the "peakedness". The formula proposed by Folk is: kg = ϕ95 −ϕ5 2.44(ϕ75 − ϕ25) k g = ϕ 95 − ϕ 5 2.44 ( ϕ 75 − ϕ 25) Kurtosis is measured in phi units as well. It can be used to determine the number of outliers in the sample.

Particle Size

The size of contaminants and particles are usually described in microns, a metric unit of measure where. one micron is one-millionth of a meter. 1 micron = 10-6 m = 1 μm. In imperial units. 1 inch = 25400 microns. 1 micron = 1 / 25400 inch. The eye can in general see particles larger than 40 microns. Typical size of contaminants and particles ...

Standards | FEPA

For abrasives, particle size is carefully controlled in accordance with FEPA''s own developed European standards, FEPA grain standards. Grit sizes, measures and appellation differ depending on abrasive products: Superabrasives: The grit designation is prefixed with a "D" to denote Diamond and a "B" to denote cBN.
