Principle
Measurement of the angle at the base of the cone of aluminium oxide obtained by allowing a sample to fall through a fixed distance from a defined funnel onto a horizontal base plate.

Apparatus
-Funnel, of stainless steel, having a nozzle of internal diameter 6 mm, fitted with a sieve of 1 mm retaining plates. The funnel is screwed into its support.
-Base-plate, of minimum length 270 mm and minimum width 200 mm. It shall be perfectly rigid and made of chrome-plated iron. On the polished surface of the base-plate, four straight lines are engraved at angle of 45 degree to each other; at their intersection is a locating pin to which the height block can be fixed. It is provide with three adjustable leveling feet.
-Funnel support, made in stainless steel and of substantial construction. It is designed so that the axis of the funnel is vertically over the central locating pin.
-Height block, consisting of a metal cylinder with polished faces of height 40 min. The base has a recess to engage the central locating pin of the base-plate.
