AS 5009.1:2003 pdf free.Determination of particle size distribution by centrifugal liquid sedimentation methods Part 1: General principles and guidelines. This correction is usually applied in the equipment software. The value of E is unity for large particles, rising to 2 as the particles pass through the Mie scattering region (about 0,5 him), and rapidly reducing as the particle size decreases...

AS 4816.1–2002 pdf free download.Determination of particle size distribution by gravitational liquid sedimentation methods Part 1: General principles and guidelines. Sedimentation techniques may be classified as either incremental or cumulative. Incremental methods are used to determine the solids concentration (or suspension density) of a thin layer at a known height and time. Cumulative methods are used to determine the rate...
