1、Designation:D219903(Reapproved 2013)Standard Test Method forMeasurement of Plasticizer Migration From Vinyl Fabrics toLacquers1This standard is issued under the fixed designation D2199;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,

2、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.Scope1.1 This test method covers an accelerated test for themeasurement of a tendency for plasticizers in finished vinyl

3、fabric to be transferred to coatings with which they come incontact.NOTE1Age of fabric sample may affect results of test.To ensure mostreliable results,test with fabric sample closest in age to what will becoated.1.2 The values stated in SI units are to be regarded as thestandard.The values given in

4、 parentheses are for informationonly.1.3 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 limita

5、tions prior to use.2.Summary of Test Method2.1 A small sample of vinyl fabric is placed on a condi-tioned coating film under a pressure of 3.45 kPa(12psi).Theassembly is placed in an oven for 3 days at elevated tempera-ture.At the end of that time,the coating is examined formarring or softening.For

6、coatings that may block or print at50C or lower,a lower test temperature and a longer test timemay have to be used.3.Significance and Use3.1 Plasticizers in finished vinyl fabric can be transferred tocoatings with which they come in contact.When this takesplace,objectionable marring and softening oc

7、cur.This testmethod covers an accelerated test for measurement of thistendency.4.Apparatus4.1 Drawdown Blade,125-m(5-mils)clearance to providea wet film of approximately 63 m(2.5 mils)in thickness.4.2 Plate Glass Panels.4.3 Window Glass,51 by 51-mm(2 by 2-in.)square,doublestrength.4.4 Sponge Rubber,

8、51 by 51-mm(2 by 2-in.)square by14in.(6.3 mm)thick.4.5 Weights,flat-bottom,sufficient to place a total weight of910 g(2 lb)on each test sample.4.6 Forced-Convection Oven,thermostatically controlled to62C.4.7 Photograph Roller.24.8 Aluminum Foil.5.Procedure5.1 Apply the coating to the glass panel wit

9、h the drawdownblade to provide a uniform film with an area of at least a51-mm(2-in.)square and a dry thickness of at least 25 m(1mil)or as agreed upon.Dry the coating in accordance with therecommendations of the manufacturer or for a minimum of 24h at room temperature and 2 h at 50C.5.2 Preheat the

10、glass plate bearing the coating,the 51 by51mm(2 by 2-in.)glass square,and the weights for 30 min at50C.Place the square of vinyl fabric on the coating with careand ensure intimate contact by rolling with the photographicroller.Cover the fabric with foil,sponge rubber,glass,andweight in that order.Th

11、e total weight shall be 910 g(2 lb).5.3 Place the assembly in the forced convection oven at atemperature of 50C for 72 h.After removal from the oven andcooling,remove the weight,sponge rubber,and aluminum foil,and carefully remove the vinyl fabric.Note and report anyresistance to removal.Wipe the su

12、rface of the fabric with a softrag dampened with heptane and examine for removal ofexuded plasticizer.6.Rating6.1 Rate the degree of migration by viewing the surface ofthe coating at a low angle against the light within 2 h aftertermination of heating and within 15 min of removal of thefabric.1This

13、test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings,Materials,and Applications and is the direct responsibility ofSubcommittee D01.55 on Factory Applied Coatings on Preformed Products.Current edition approved June 1,2013.Published July 2013.Originally approvedin

15、nochange,faint imprint,severe imprint,or marring.7.2 If plasticizer is evident when the surface is wiped,thisshall be reported.8.Precision and Bias8.1 PrecisionIt is not possible to specify the precision ofthe procedure in Test Method D2199 for measuring plasticizermigration since the test result is

16、 nonquantitative.Repeated testshave demonstrated that several laboratories will assign thesame rating to various coating fabric combinations.Also,replicate tests by one laboratory are in good agreement.8.2 BiasNo information can be presented on the bias ofthe procedure in Test Method D2199 for measuring plasticizermigration since no material having an acceptable referencevalue is available.9.Keywords9.1 lacquer;plasticizer migration;vinyl fabricsASTM International takes no position respecting th
