Green Hardness Tester "B" Scale
It is used to determine the surface hardness of Green Sand Mould and it Meets AFS (American Foundry Society) standards.
It works on a principle base on the Brinell Hardness Testing Machine. The Hardness test can be made in seconds. The user simply presses the tester against the mold surface and notes the reading on the dial. Excessive pressure will not alter the reading.
A 1/2 “(12.7 mm) radius ball contact point is loaded with a spring pressure of 9.604 N. The softer the mold surface, the greater the penetration into the mold.
A mold offering no resistance to the contact point would have a zero reading and one having hardness capable of preventing penetration would read 100.
Operates in any position. A maximum reading stop holds the reading when testing in blind portions of the mold.
