Tests sand to determine its usability for making sand molds or cores: Collects samples of sand mixes and compresses sand into sample piece, using specimen sand rammer. Determines properties of sand samples, such as moisture content, permeability, compression and shear strength, clay content, and sand-grain size and distribution, using sand-test equipment, such as moisture teller, permeability meter, sand-strength tester, and sieve set. May perform similar tests on ladle lining refractories. May test quality of incoming materials, such as cereal or core oils to be used in sand mixes by mixing and testing sand samples.
