Designation:D471312Standard Test Methods forNonvolatile Content of Heatset and Liquid Printing InkSystems1This standard is issued under the fixed designation D4713;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.Scope*1.1 These test methods cover the determination of weightcontent of nonvolatile matter in two types of printing inks.1.2 Test MethodAis applicable to heatset-type printing inksand resin solutions;solvents in such systems typically haveinitial boiling points in the range from 240 to 275C(470 to535F)and vapor pressures less than 0.2 mm Hg.1.3 Test Method B is applicable to liquid-type printing inksand vehicles based on aqueous or organic solvents that evapo-rate readily at ordinary room temperatures.NOTE1Test Method A(for heatset systems)specifies a specimen filmthickness that is much thinner than those produced by related testmethods;one exception is Test Method B in Test Methods D1259,whichis recommended as a referee test.NOTE2Test Method B(for liquid ink systems)is similar to TestMethod D2369 except that a solvent is not required for spreading the testspecimen.1.4 The values stated in SI units are to be regarded as thestandard.The values given in parentheses are for informationonly.1.5 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:2D1259 Test Methods for Nonvolatile Content of ResinSolutionsD2369 Test Method for Volatile Content of CoatingsE1 Specification for ASTM Liquid-in-Glass ThermometersE145 Specification for Gravity-Convection and Forced-Ventilation OvensE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method3.Summary of Test Methods3.1 Test Method AHeatset Systems.A 0.15-g specimen ismechanically spread in a 57-mm weighing dish to a nominalthickness of 80 6 10 g/m2and heated in a forced ventilationoven at 110C for 3 h.3.2 Test Method BLiquid Ink Systems.A0.5-g specimen isdispensed into a 57-mm weighing dish by means of a dispos-able syringe,mechanically spread out,and heated in an oven at110C for 1 h.4.Significance and Use4.1 Nonvolatile content of printing inks is useful for speci-fication acceptance between the producer and the user.4.2 In order to obtain accurate results for heatset systemswithin the specified 3-h heating time,the specimen filmthickness must be less than 100 g/m2,and the oven must haveforced ventilation.Thickness of the specimen film is lesscritical for liquid ink systems.5.Apparatus5.1 Balance,accurate to 1 mg.5.2 Oven,forced-ventilation type conforming to Type IIB inSpecification E145 and maintained at 110 6 2C.5.3 Thermometer,capable of reading 110 6 2C and con-forming to Specification E1.Alternately,temperature measur-ing devices such as liquid-in-glass thermometers,thermistors,thermocouples,or platinum resistance thermometers that pro-vide equivalent or better accuracy and precision,that cover thetemperature range specified,may be used.5.4 Weighing Dish,such as an aluminum foil dish 57 mmwide,the lid of a 1-lb ink can 94 mm wide,or otherflat-bottomed container.The bottom of the container must nothave a trough or depression into which the test material mightcollect.5.5 Spatula,or small ink knife.1These test methods are under the jurisdiction of ASTM Committee D01 onPaint and Related Coatings,Materials,and Applications and are the directresponsibility of Subcommittee D01.56 on Printing Inks.Current edition approved Nov.1,2012.Published November 2012.Originallyapproved in 1987.Last previous edition approved in 2007 as D4713 92(2007).DOI:10.1520/D4713-12.2For 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.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.6 Spreading Device,one per weighing dish,of heat-stablematerial,such as a glass stirring rod or thick L-shaped wire.5.7 Forceps,5.8 Desiccator,5.9 Syringe3(for liquid ink systems only),single-use 2 to5-mL capacity without needle,or other weighing device listedin the Apparatus section of Test Methods D1259.6.Reagents6.1 Toluene,technical grade.7.Preparations of Equipment and Sample7.1 Check the levelness of shelving in the oven;adjust,ifnecessary.Lay the thermometer or temperature measuringdevice on shelf with the bulb or sensor at the place where thesamples will
