Q. How can you test hardness of the prepared mould?

Hardness test: The hardness of the prepared mould surface is tested to check the ramming density of the sand. The instrument resembles a dial indicator, and carries a spring loaded steel ball of 5 mm. The ball is pressed into the rammed surface. The depth of penetration of the ball is indicated on the dial of the indicator in terms of hardness units.
