ASTM D4017-22 Standard Test Method for the Determination of Moisture in Paints and Paints Materials by the Carl Fisher Method specifies standard test procedures for the determination of Moisture content in paints and their raw materials by the Carl Fisher Method. The Carl Fisher Method is an accurate chemical analysis method widely used to quantify moisture in paints, coatings and related materials. The standard details the instrumentation required for the test, reagent preparation, operation procedures and data calculation methods to ensure the accuracy and conformity of the test results. Moisture content determination is crucial for the Stability, quality control and performance evaluation of paints. Excessive moisture may lead to poor Coating drying or affect its durability. This method provides a reliable moisture detection tool for Coating manufacturers and quality control personnel.
