Scope

This International Standard sets out a method for determining the amount of time taken for a given quantity of smelter-grade alumina to flow by gravity through a precisely constructed standard funnel. NOTE Variations in the apparatus and other test variables can create significant inter-laboratory differences in results. (See Table A.1.)
