Permeability (foundry sand) - Wikipedia

Permeability is a property of foundry sand with respect to how well the sand can vent, i.e. how well gases pass through the sand. And in other words, permeability is the property by which we can know the ability of material to transmit fluid/gases. The permeability is commonly tested to see if it is correct for the casting conditions.

Sand testing - slideshare.net

Dec 22, 2017 · Permeability test According to the definition of the American Foundrymen’s Society (AFS) permeability means a physical property of the moulding sand which allows gasses to pass through it. That is determined by flow of air through the AFS standard specimen under a standard pressure.

Foundry sand testing - Wikipedia

Foundry sand testing is a process used to determine if the foundry sand has the correct properties for a certain casting process. The sand is used to make moulds and cores via a pattern. In a sand casting foundry there are broadly two reasons for rejection of the casting — metal and sand — each of which has a large number of internal variables.
