The ASTM D 3960-2018 standard specifies a method for determining vocs (VOC) content in paints and related coatings. The standard details how VOC content can be calculated using the applicable ASTM test method and provides formulas for calculations including the amount of VOC per unit volume of coating minus water and exempt volatile compounds, Coating solids per unit volume, and Coating solids per unit mass. Determination of VOC content is critical for comparing the amount of VOC released by different coatings under the same application conditions. The standard also states that VOC content calculations should take into account the volume of Coating solids to allow for accurate linear comparisons. The standard applies to solvent-based and water-based paints and provides guidance for the selection of appropriate test methods.
