Designation:D187416Standard Specification forWater-or Solvent-Soluble Liquid Adhesives for AutomaticMachine Sealing of Top Flaps of Fiberboard ShippingCases1This standard is issued under the fixed designation D1874;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.Scope1.1 This specification covers starch,dextrin,casein,resinbase,and other liquid adhesives(excepting pressure-sensitivetypes)used for sealing the top flaps of fiberboard shippingcases.It includes provisions for adhesive selection based on:(1)satisfactorymachiningcharacteristicsonspecificequipment,and(2)adequate adhesion under specified storageconditions.This specification further provides for the controlof uniformity between lots of an adhesive selected on the abovebases by limiting variations in nonvolatile content and viscos-ity.1.2 This specification provides bases for adhesive selectionas well as product uniformity control.Test methods arespecifiedformeasuring(1)nonvolatilecontent,(2)consistency,and(3)bonding permanency under specifiedstorage conditions.1.3 The values stated in acceptable metric units are to beregarded as the standard.The values given in parentheses areprovided for information purposes only.2.Referenced Documents2.1 ASTM Standards:2D907 Terminology of AdhesivesD1084 Test Methods for Viscosity of AdhesivesD1489 Test Method for Nonvolatile Content of AqueousAdhesivesD1581 Method of Test for Bonding Permanency of Water-orSolvent-Soluble Liquid Adhesives for Labeling GlassBottles(Withdrawn 1991)3D1714 Test Method for Water Absorptiveness of FiberboardSpecimens for Adhesives(Withdrawn 1990)33.Terminology3.1 Many terms in this specification are defined in Termi-nology D907.4.Physical Properties4.1 The general consistency shall be uniform,and theadhesive shall be free of lumps and particles.4.2 The machining properties shall be such that the adhesive(when diluted in accordance with to the manufacturers instruc-tions)shall not string when machine transfer surfaces areseparated,shall not build up excessively on machine parts,andshall not foam.4.3 The bonding permanency of the adhesive shall providea minimum of 75%paper fiber tear when tested under theexposure conditions specified in the contract or purchase order.The exposure conditions shall be selected from those in Table 1of Test Method D1581.5.Permissible Variations5.1 The nonvolatile content of the adhesive shall be within61.5%of that specified in the contract or purchase order.5.2 The consistency of the adhesive shall be within 620%of that specified in the contract or purchase order.6.Sampling6.1 The adhesive sample shall be a 0.9-L(1-qt)aliquotconsisting of a composite taken when possible from three ormore separate containers chosen at random.Samples also shallbe taken from containers that appear to be nonrepresentativeand shall be tested separately.Before a sample is withdrawn,mix the contents in the container to uniform consistency.Placethe sample immediately in an airtight glass jar until tested.6.2 Samples of adhesives used on fiberboard cases shall beof the same type used on the production line.Samples ofboards used for all bonding permanency tests shall be within adefined range of water absorptiveness to eliminate this variable1This specification is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.14 on Tape andLabels.Current edition approved May 1,2016.Published June 2016.Originallyapproved in 1961.Last previous edition approved in 2010 as D1874 62(2010).DOI:10.1520/D1874-16.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 from the test.The specific range shall be selected by thepurchaser and shall be based upon the adhesive for shippingcases used on the production line.6.3 Test a minimum of six board or board-facing materialssamples in selecting the sample for each adhesion study.Rejectsamples that fail to fall within 650%of the selected waterabsorptiveness values.6.4 Condition samples at 23 6 1C(73.4 6 1.8F)and 506 2%relative humidity prior to each adhesion test to ensureuniformity.7.Test Methods7.1 Nonvolatile ContentTest Method D1489.7.2 ConsistencyMethod B(rotational viscometer)orMethod C(Stormer viscometer)of Test Methods D1084.7.3 Bonding PermanencyTest Method D1581.7.4 Water AbsorptivenessTest Method D1714.8.Number of Tests8.1 The number of test specimens shall be as specified ineach metho
