This document specifies a method for the determination of the water content of water-borne coating materials and their raw materials by using a gas chromatograph. The preferred working range of this test method is from a water mass fraction of 15 % to a water mass fraction of 90 % but the method can be applied outside of this range.<\/p>\n
