Designation: D4713 − 12Standard Test Methods forNonvolatile Content of Heatset and Liquid Printing InkSystems 1This standard is issued under the f i xed 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 275°C (470 to535°F) 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.N OTE 1—Test Method A (for heatset systems) specif i es a specimen f i lmthickness 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.N OTE 2—Test 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.

Summary of Test Methods3.1 Test Method A—Heatset Systems. A 0.15-g specimen ismechanically spread in a 57-mm weighing dish to a nominalthickness of 80 6 10 g/m 2 and heated in a forced ventilationoven at 110°C for 3 h.3.2 Test Method B—Liquid 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 at110°C for 1 h.4. Signif i cance and Use4.1 Nonvolatile content of printing inks is useful for speci-f i cation acceptance between the producer and the user.4.2 In order to obtain accurate results for heatset systemswithin the specif i ed 3-h heating time, the specimen f i lmthickness must be less than 100 g/m 2 , and the oven must haveforced ventilation. Thickness of the specimen f i lm is lesscritical for liquid ink systems.5. Apparatus5.1 Balance, accurate to 1 mg.5.2 Oven, forced-ventilation type conforming to Type IIB inSpecif i cation E145 and maintained at 110 6 2°C.5.3 Thermometer, capable of reading 110 6 2°C and con-forming to Specif i cation 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 specif i ed, 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 otherf l at-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.1 These 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.
