Designation:D148909(Reapproved 2021)Standard Test Method forNonvolatile Content of Aqueous Adhesives1This standard is issued under the fixed designation D1489;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.This standard has been approved for use by agencies of the U.S.Department of Defense.This test method replaces Method 4021 of Federal Test Method Standard No.175a.1.Scope1.1 This test method covers the determination of the non-volatile content of aqueous adhesives,such as dextrin,starch,casein,and animal gelatin.1.2 The values stated in SI units are to be regarded as thestandard.The values given in 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D907 Terminology of Adhesives3.Terminology3.1 DefinitionsMany terms in this test method are definedin Terminology D907.4.Significance and Use4.1 Adhesive cost is often related to the solids level(non-volatile content).4.2 This test method can be used to compare the nonvolatilecontent of various adhesives for adhesive selection and productuniformity.4.3 This test method is suitable for quality control andresearch purposes.5.Apparatus and Materials5.1 Analytical Balance,for weighing of specimen,accurateto 60.001 g.5.2 Laboratory Balance,for weighing of sample,accurateto 60.01 g.5.3 Constant-Temperature Oven,capable of maintaining atemperature of 105 6 1C(221 6 2F).5.4 Glass Jar,of sufficient size,1 L or more,to store sampleof adhesive prior to testing.The jar shall be such that it can besealed to prevent the loss of volatile content during the storageperiod.5.5 Beaker,of 100 mL capacity.5.6 Weighing BottlesWide-mouth cylindrical glass weigh-ing bottles,of flat form,about 30 mm in height and 50 mm indiameter,having interchangeable ground-in glass caps.5.7 Volumetric Flasks,of 200-mL capacity,with glass stop-pers.5.8 Volumetric Pipet,of 10-mL capacity.5.9 Desiccator,with drying agent and tray.5.10 Silica Sand.5.11 Water,HotDistilled water heated to at least 80C.5.12 Hot Plate,used to heat the water.6.Sampling6.1 The sample of the adhesive shall be representative of thelot being evaluated.The quantity shall be at least 1.0 L aliquotconsisting of a composite taken,when possible,from three ormore separate containers chosen at random.Thoroughly mixthe sample to uniform consistency.Immediately place thecomposite sample in an airtight glass jar until tested.1This test method is under the jurisdiction of ASTM Committee D14 onAdhesives and is the direct responsibility of Subcommittee D14.10 on WorkingProperties.Current edition approved April 1,2021.Published April 2021.Originallyapproved in 1957.Last previous edition approved in 2016 as D1489 09(2016).DOI:10.1520/D1489-09R21.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.17.Procedure7.1 Make sure that the sample in the glass jar is of uniformconsistency before removing a specimen for testing.Inspectthe sample to ensure that there are no signs of settling orseparation of the adhesive.If settling or separation are noted,mix the samples thoroughly.Other factors,such as foaming orcontamination may require the samples be replaced.7.2 Test three 10-g specimens from each composite sample.7.3 Weigh about 10 g of adhesive into a small beaker to thenearest 0.01 g.Disperse in 50 mL of hot distilled water andtransfer to a 200-mL volumetric flask.Rinse the beaker withsmall portions of hot distilled water and add rinsings to theflask.Dilute to mark with hot distilled water.Perform duplicatetests on each dispersion prepared in this manner.7.4 Pipet 10 mL of the dispers
