How is Moisture Content Tested?

The basic method is to carefully weigh the specimen in its original state, drying the water contained in the specimen, then re-weighing. Precisely HOW this is done depends upon the material. Usually this is done in a large oven-like chamber at a temperature above the boiling point of water, but for especially sensitive materials, other techniques can be used, for example long drying times at reduced temperatures, or by heating the material in a vacuum chamber. The reduced atmospheric pressure causes a lower boiling point in the water, but often has no effect on the material, this brings the required test temperature below the point where damage to the sample would occur.
