Standard Test Method for Determination of Weight Percent Volatile Content of Water-Borne Aerosol Paints

SIGNIFICANCE AND USE
4.1 Calculation of the weight percent volatile organic content of water-borne paints, requires that the water content be known. This test method provides a direct way to determine the weight percent volatile organic matter of water-borne aerosol paints minus the matter content. This test method is modeled after Method 36.4
SCOPE
1.1 This test method is for the determination of the weight percent volatile content of water-borne paints in aerosols.  
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
