What is the Baume Test?
The Baume test is the most common test used in foundries to control coating operations because it is both quick and easy. The test is performed with a hydrometer, which is a sealed glass tube that contains a calibrated scale in degrees Baume.
The hydrometer should be clean and dry with a resolution of at least 0.5 degrees. The gauges reference the material they ate to be used for and the temperature the material should be to achieve measurement accuracy. The Baume scale of numbers relates to the specific gravity and body of a coating.
After mixing the coating sample thoroughly, the hydrometer is immediately floated into the coating slurry. When it stops sinking, the degrees Baume can be read directly from the hydrometer. This test requires that the coating be homogeneous, at the correct temperature have no air bubbles and be completely still.
