The test consists of two sieving operations. First, using test sieves, the sample is separated into various particle size fractions. Each of the particle size fractions is then sieved using bar sieves which have parallel slots. The overall flakiness index is calculated as the total mass of particles passing the bar sieves expressed as a percentage of the total dry mass of particles tested.
