1、Designation:D471312(Reapproved 2020)Standard 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
2、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 These test methods cover the determination of weightcontent of nonvolatile matter in two types of printing inks.1.2
3、 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
4、 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 r
5、eferee 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
6、 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international sta
