ASTM D5325-03 (2021) "Standard Test Method for Determining Percent Volatile Content of Waterborne Aerosol Coatings Weight" specifies a test method for determining the weight percentage of volatile components in waterborne aerosol Coatings. This method calculates the content of volatile components by heating and weighing the Coating sample, providing important information about the Coating composition. The standard details the test equipment, sample preparation, test conditions and data calculation methods to ensure the accuracy and conformity of the test. This method is suitable for the research and development, quality control and regulatory compliance testing of waterborne aerosol Coatings, providing a scientific basis for the environmental performance evaluation and formulation optimization of Coatings.
