ASTM D3792-16 (2022) Standard Test Method for Direct Injection Gas Chromatograph of Water Content in Coatings specifies a standard test method for the determination of Moisture content in coatings by direct injection of Gas Chromatograph. This method uses gas phase chromatograph technology to directly analyze the moisture content in coatings and coatings. It has the characteristics of high-precision and fast, and is suitable for various coating materials, such as paints, varnish, etc. This test method can effectively evaluate the effect of moisture in coatings, thereby helping to control the mass and performance of coatings, and avoid the adverse effects of moisture on coating curing, adhesion and Miscellaneous physical properties. This standard provides a scientific and standardized testing tool for the coatings industry, which is widely used in the fields of quality control, Product Research & Development, and technical testing.
