1、Designation:D147602(Reapproved 2012)Standard Test Method forHeptane Miscibility of Lacquer Solvents1This standard is issued under the fixed designation D1476;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A
2、 number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope*1.1 This test method covers determination of the miscibility
3、of lacquer solvents with heptane.It may also be used to detectqualitatively the presence of moisture in esters and ketones.NOTE1For the quantitative determination of water content,see TestMethod D1364.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are i

6、agent Titration Method)3.Significance and Use3.1 Water in a solvent may interfere with many uses of thesolvent.This test method provides a measure of the miscibilityof lacquer solvents with a nonpolar medium-heptane.It alsoprovides a qualitative indication of the presence or absence ofmoisture in th
7、ese solvents(often esters and ketones).Theresults of these measurements may be used for specificationacceptance.4.Reagents4.1 Heptane,containing not less than 99%n-heptane.NOTE2Detailed requirements for 99%n-heptane are specified inTable 1 of Test Method D611.5.Procedure5.1 Both the specimen and the
8、 heptane shall be at atemperature of 20 6 1C.Transfer 5 mL of the specimen to a100-mL glass-stoppered(graduated)cylinder and add 5-mLincrements of heptane until the total specified volume(usuallyspecified as 19 volumes or 95 mL)has been added,shakingwell after each addition.A clear solution indicate
9、s miscibilityand a turbid solution indicates immiscibility or the presence ofwater in the specimen,or both.6.Report6.1 If the solution remains clear after the addition of thespecified amount of heptane,report the specimen as passingthis test.7.Precision and Bias7.1 Because of the pass-fail nature of
