Describes a sieving procedure for determining the American Foundrymen's Society Grain Fineness Number (AFS Number) for heavy mineral sand concentrates.

This standard sets out a method of determining the American Foundrymen's Society Grain Fineness Number (AFS Number) for heavy mineral sand concentrates.NOTE: The complete AFS fineness test involves the removal of clay and fines prior to sizing. However, in this case it is normally unnecessary since heavy mineral sands are substantially free from clays.
