17、lopment of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.1NOTE 3Since these inks do not contain water or any materialscurrently classified by US EPA as negligibly photochemically reactive(exempt solvents), volat

18、ile organic compound content is the same asvolatile content. The volatile organic compounds in these inks are highboiling hydrocarbon oils which are, according to US EPAguidelines, 95 %retained in the printed substrate or oxidized into the ink film. Therefore,the mass of volatile organic compound em

19、itted from the ink would becalculated as only 5 % of the volatile organic compound content of the inkas derived from the results of this test method.5. Apparatus5.1 Aluminum Foil Dishes, 58 mm in diameter by 18 mmhigh with a smooth (planar) bottom surface. Precondition thedishes for 30 min. in an ov

20、en at 110 6 1C and store in adesiccator prior to use. Use tongs or rubber gloves or both, tohandle the dishes.5.2 Desiccator, equipped with a general purpose desiccantsuch as anhydrous calcium sulfate.5.3 Forced Draft Oven, Type IIA or Type IIB as specified inSpecification E145.NOTE 4Be sure the she

21、lves are level.5.4 Ink Knives or Taper Knives, suitable for transferring thesmall specimen from the original sample container to thealuminum dish.5.5 Paper Clips, bent for use as stirrers. Precondition thebent paper clips along with the aluminum foil dishes, asdescribed in 5.1.5.6 Analytical Balance

22、, capable of weighing to 0.0001 g.5.7 Stopwatch, capable of reading to 1s.6. Reagents6.1 Toluene, technical grade, in accordance with Specifica-tion D362.7. Procedure7.1 Weigh a preconditioned foil dish that has been equippedwith a preconditioned bent paper clip to 0.0001g and record asW1. Similarly

23、 weigh a duplicate.7.2 Mix the sample by hand using an ink knife (taper knife)prior to extracting the exact specimens to be used in the test.7.3 Weigh a 0.300 g 6 0.001 g specimen directly into eachof the weighed dishes. Record the specimen weight to 0.0001gasS.NOTE 5Due to the relatively high visco

24、sity and low volatility ofsheet-fed and coldset web offset inks, this may best be achieved using inkknives (taper knives). The quickest way to achieve this specimen size andprecision is to slightly overweigh and then remove tiny amounts using thetip of a clean ink knife.7.4 To each dish add 1 mL of

25、toluene and stir, using the bentpaper clip, into the ink specimen. Then add a further 2 mL oftoluene (for a total of 3 mL) and repeat the stirring to achievea homogeneous dispersion.7.5 Heat the aluminum foil dishes containing the dispersedspecimens in the forced draft oven (5.3) for exactly 60 min.

26、 at110 6 1C. The bent paper clips should remain in the dishesthroughout the test. Position the dishes as near to the center ofthe oven as possible. Use the stopwatch to time the 60-minoven exposure.7.5.1 Warning:In addition to other precautions, provideadequate ventilation, consistent with accepted

27、laboratorypractice, to prevent solvent vapors from accumulating to adangerous level.7.6 Remove the dishes from the oven, place immediately ina desiccator, cool to ambient temperature, and weigh to0.0001g. Record weight as W2.8. Calculation8.1 For each specimen, calculate the weight percent volatilem

29、ht percent volatile matter.9. Precision and Bias9.1 PrecisionTwo separate interlaboratory studies of thistest method were conducted. In the first, operators in 10laboratories tested in triplicate 5 coldset web offset black inkswhose volatile content ranged from 3 to 39 %. In the second,operators in

30、9 laboratories tested in triplicate 5 sheet-fed offsetinks whose volatile content ranged from 7 to 23 %. The testresults were analyzed in accordance with Practice E691.Inthesame interlaboratory studies, the full range of temperature andsample sizes permitted by Test Method D2369 was alsostudied. The

31、 precision, characterized by repeatability (Sr, r)and reproducibility (SR, R) was much better for the test methoddescribe herein. Repeatability was improved by a factor of 4.2for the web offset inks and 3.1 for the sheet-fed inks.Reproducibility was improved by a factor of 1.3 for the coldsetinks an

32、d by a factor of 1.6 for the sheet-fed inks. Based on thestatistical analysis of the results, the following criteria shouldbe used for judging the acceptability of results at the 95 %confidence level:9.1.1 RepeatabilityTwo results, each the mean of dupli-cate determinations, obtained by the same ope

33、rator should beconsidered suspect if they differ by more than 13 % relative forcoldset web offset inks and by more than 7 % relative forsheet-fed offset inks.9.1.2 ReproducibilityTwo results, each the mean of dupli-cate determinations, obtained by operators in different labora-tories should be consi

34、dered suspect if they differ by more than54 % relative for coldset web offset inks and by more than 16% relative for sheet-fed offset inks.9.2 BiasBias cannot be determined as there are no stan-dard materials.D6419 00 (2017)210.
