Designation:D520003(Reapproved 2014)Standard Test Method forDetermination of Weight Percent Volatile Content of Solvent-Borne Paints in Aerosol Cans1This standard is issued under the fixed designation D5200;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method is for the determination of the weightpercent volatile organic compounds of solvent-borne paints inaerosol cans.It offers a unique way to obtain paint specimensfrom aerosol cans.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.A specific hazardstatement is given in 6.7.2.Referenced Documents2.1 ASTM Standards:2E145 Specification for Gravity-Convection and Forced-Ventilation OvensE180 Practice for Determining the Precision of ASTMMethods for Analysis and Testing of Industrial and Spe-cialty Chemicals(Withdrawn 2009)32.2 Other Standard:Method 35 Determination of Percent Volatile Organic Com-pounds(VOC)in Solvent Based Aerosol Paints43.Summary of Test Method3.1 Adesignated quantity from an aerosol coating is sprayedinto an adapter glass tube assembly and heated in an oven at110 6 5C for 60 min.The percent volatile is calculated fromthe loss in weight.4.Significance and Use4.1 This test method is the procedure of choice for deter-mining the volatile content in aerosol coatings under specifiedtest conditions modeled after Method 35.4The inverse value,nonvolatile,is used to determine the weight percent solidscontent.This information is useful to the paint producer,user,and to environmental interests for determining the grams ofvolatile organic compounds per gram of solids emitted fromaerosol cans.5.Apparatus5.1 Adapter Glass Tube Assembly,(Fig.1).5.1.1 Sample Adapter Tube,straight connecting with 35/25spherical joints.Loosely fill with glass wool and preconditionfor 30 min in an oven at 110 6 5C and store in a dessicatorprior to use.5,65.1.2 Charcoal Adapter Tube,straight connecting with35/25 spherical joints.Fill with activated charcoal and plugboth ends with glass wool.This tube is used to prevent thesolvent vapors from contaminating the vacuum pump.6,75.1.3 Adapters,connecting hose with 35/25 socket joints.6,85.1.4 Adapter,6,9connecting hose with 35/25 ball joint.1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.21 on Chemical Analysis of Paints and Paint Materials.Current edition approved July 1,2014.Published July 2014.Originally approvedin 1991.Last previous edition approved in 2008 as D5200 03(2008)1.DOI:10.1520/D5200-03R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.4Bay Area Air Quality Management District,(BAAQMD)Manual ofProcedures,Vol III,939 Ellis St.,San Francisco,CA 94109.5The sole source of supply of the adapter tube,No.5035-35 known to thecommittee at this time is Ace Glass Inc.,P.O.Box 688,1430 Northwest Blvd.,Vineland,NJ 08360.6If you are aware of alternative suppliers,please provide this information toASTM International Headquarters.Your comments will receive careful consider-ation at a meeting of the responsible technical committee,1which you may attend.7The sole source of supply of the charcoal adapter tube,No.5035-3 known tothe committee at this time is Ace Glass Inc.8The sole source of supply of the adapters(socket joints)No.5217-35 known tothe committee at this time is Ace Glass Inc.9The sole source of supply of the adapter(ball joint)No.5216-35 known to thecommittee at this time is Ace Glass Inc.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.1.5 Clamps,pinch type,with screw-locking device.6,105.1.6 Glass Wool,medium-fine silk.5.1.7 Activated Charcoal,coconut,8 to 12 mesh.5.1.8 Tygon Tubing.5.1.9 Iron Stands.5.1.10 Utility Clamps.5.2 Vacuum Pump.5.3 Forced Draft Oven,Type II A or Type II B as specifiedin Specification E145.5.4 Actuators(Valves),with extension tubes.5.5 Top-Loading Balance,capable of weighing to 0.01 g.5.6 Shaker,similar to the Eberbach shaker in Fig.2.6.Procedure6.1 Mix the aerosol can thoroughly using a shaker,similarto the Eberbach shaker in Fig.2,f
