Designation:D 5328 92(Reapproved l997)Standard Test Method forVolatile Organic Compound(VOC40)Content of Non-HeatsetPaste Printing Ink Systems at 40C1This standard is issued under the fixed designation D 5328;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of the volatileorganic compound(VOC40)content of non-heatset printingink systems of the paste type using a baking cycle of 1 h at40C.1.2 This test method is applicable to paste printing inks andvehicles that dry primarily by absorption,polymerization,orrelated means without the application of heat.Such systems donot contain appreciable quantities of low-boiling solvents thatevaporate readily at ordinary room temperatures.NOTE1The 40C baking temperature in this test method is the sameas that specified in Bay Area Method 30.The temperature of heating is110C in several related test methods,for example,D 2369,D 4713 andEPA Reference Method 24.VOC determinations are reviewed in ASTMManual Series MNL 4.21.3 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.2.Referenced Documents2.1 ASTM Standards:D 1475 Test Methods for Density of Paint,Varnish,Lacquerand Related Products3D 2369 Test Methods for Volatile Content of Coatings3D 3792 Test Method for Water Content of Water-ReduciblePaints by Direct Injection into a Gas Chromatograph3D 3960 Practice for Determining Volatile Organic Com-pound(VOC)Content of Paints and Related Coatings3D 4017 Test Method for Water in Paints and Paint Materialsby Karl Fischer Method3D 4713 Test Methods for Nonvolatile Content of Heatsetand Liquid Printing Ink Systems4E 1 Specification for ASTM Thermometers5E 145 Specification for Gravity-Convection and Forced-Ventilation Ovens6E 691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of Test Methods62.2Other Standards:EPA Federal Reference Method 24Determination ofVolatile Matter Content,Water Content,Density,VolumeSolids,and Weight Solids of Surface Coatings7Method 30Determination of Volatile Organic Compounds(VOC)in Solvent-Based Non-Heatset Inks83.Terminology3.1 DefinitionsDefinitions pertaining to this test methodare covered in Practice D 3960.4.Summary of Test Method4.1 The test material is spread in a weighing dish to anominal thickness corresponding to about 115 g/m2.Theweight percent of total volatile compounds is determined afterheating at 40C for one h.4.2 The typical paste ink does not contain water or exemptsolvents;in such cases,the volatile organic content is the sameas the total volatile content.If the test sample is based on anemulsion system or is suspected of containing more than 5%water,the water content is determined by the Karl Fischermethod or by gas chromatography.4.3 The density of the test sample is measured,and thevolatile organic content in weight percent at 40C is convertedto units of grams per litre or pounds per gallon.Alternatively,if the water content was found to be greater than 5%,thevolatile organic content is calculated in accordance with Note3.5.Significance and Use5.1 VOC content data are required by various regulatoryagencies.This test method determines the volatile organiccontent of non-heatset paste printing ink systems at 40C inaccordance with Bay Area Method 30.This temperature isconsidered more realistic in terms of end use than the 110C1This test method is under the jurisdiction of ASTM Committee D-1 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.56 on Printing Inks.Current edition approved Nov.15,1992.Published January 1993.2Brezinski,J.J.,Manual on Determination of Volatile Organic Compounds inPaints,Inks,and Related Coatings,ASTM Manual Series MNL4,ASTM,1989.3Annual Book of ASTM Standards,Vol 06.01.4Annual Book of ASTM Standards,Vol 06.02.5Annual Book of ASTM Standards,Vol 14.03.6Annual Book of ASTM Standards,Vol 14.02.7Available from the Superintendent of Documents,U.S.Government PrintingOffice,Washington,DC 20402.8Available from Bay Area Quality Measurement District(BAAQMD),939 EllisStreet,San Francisco,CA 94109.1AMERICAN SOCIETY FOR TESTING AND MATERIALS100 Barr Harbor Dr.,West Conshohocken,PA 19428Reprinted from the Annual Book of ASTM Standards.Copyright ASTMused in several similar test methods.Due to the complexchemical composition and boiling characteristics of the oilsused in these inks,temperature of 110C may cause volatileloss that would not occur at ambient temperatures,even overextended periods of time.5.2 The inverse value,non
