Standard Test Methods for Hygroscopic Moisture (and Other Matter Volatile Under the Test Conditions) in Pigments
These test methods establish the standard procedures for determining the hygroscopic moisture (and other matter volatile under the test conditions) in pigments. Method A shall be performed on pigments that do not decompose at a specified temperature. This method shall require the use of a wide-mouth cylindrical glass weighing bottle, an oven, and an analytical balance. Method B, on the other hand, shall be used for pigments that decompose at the same specified temperature. This method shall also need a wide-mouth cylindrical glass weighing bottle, an open-tube manometer, a glass desiccator, an oil vacuum pump, and an analytical balance.
