1、Designation:D520105a(Reapproved 2014)Standard Practice forCalculating Formulation Physical Constants of Paints andCoatings1This standard is issued under the fixed designation D5201;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the

3、ribes procedures for calculating formulation values forweight solids,volume solids,solvent content,volatile organiccompound(VOC)content,hazardous air pollutant(HAP)content,and density of liquid paints and coatings.These valuesare calculated from basic formulation data.These calculationsmay be relate
