Designation:D5570/D5570M10(Reapproved 2015)Standard Test Method forWater Resistance of Tape and Adhesives Used as BoxClosure1This standard is issued under the fixed designation D5570/D5570M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers a procedure to determine thewater resistance of an adhesive or tape as measured by theamount of tape or adhesive dissolved or dispersed in water.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.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 limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D644 Test Method for Moisture Content of Paper andPaperboard by Oven Drying(Withdrawn 2010)3D996 Terminology of Packaging and Distribution Environ-mentsD1974 Practice for Methods of Closing,Sealing,and Rein-forcing Fiberboard Boxes3.Terminology3.1 Definitions:3.1.1 General definitions for packaging and distributionenvironments are found in Terminology D996.3.2 Definitions of Terms Specific to This Standard:3.2.1 box closurethe means of securing the flaps or coversof a box so that the box will not accidentally open duringnormal shipment,handling,and storage.4.Summary of Test Method4.1 Procedure AThe water resistance of a tape(gummedor pressure sensitive)is measured by immersing the tape inwater at least 24 h at 73.4 6 4F 23 6 2C and determiningthe percent of tape that is dissolved or dispersed.4.2 Procedure BThe water resistance of an adhesive ismeasured by coating the adhesive on a paper surface,immers-ing in water at least 24 h at 73.4 6 4F 23 6 2C,anddetermining the percent of adhesive that is dissolved ordispersed.5.Significance and Use5.1 When a box becomes wet,the performance of the boxand its closure are reduced.It is desirable to have box closuremethods that retain an ability to keep the box closed when wet.Sealing or reinforcing methods sometimes are useful to im-prove performance of wet boxes and closures.Water resistanceis sometimes a regulatory or contractual requirement.5.2 A test result indicating that a box closure tape oradhesive is soluble or dispersible in water is an indication thatits function will be significantly impaired when wet.A testresult that does not indicate solubility or dispersibility does notnecessarily ensure that the bonding ability will be satisfactorywhen wet or that the performance of the box closure will besatisfactory when wet.Package performance testing describedin the water resistance section of Practice D1974 is useful tofurther investigate the effects of water on package and closurefunctions.6.Apparatus and Materials6.1 Drying Oven,capable of maintaining 221 6 9F 105 65C and providing adequate air circulation.6.2 Testing Chamber,capable of keeping samples at 73.4 64F 23 6 2C.6.3 Balance,capable of reading the mass of specimens atleast to the nearest 0.00035 oz.1 mg.6.4 Container,capable of holding at least 1 qt 1 L of water.1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.27 on Paper andPaperboard Products.Current edition approved April 1,2015.Published May 2015.Originallyapproved in 1994.Last previous edition approved in 2010 as D5570 10.DOI:10.1520/D5570_D5570M-10R15.2For 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 6.5 Stainless Steel Screen,or other means of holding testspecimens under water and allowing for water to circulate totest specimens.6.6 Water,tap water is usually acceptable.Distilled ordeionized water shall be used for referee purposes.6.7 Dispensing System,as required,when adhesives are tobe tested.6.8 Specimen Marking Device,such as a pencil or a penwith water resistant ink.6.9 Paper or Paperboard,when adhesives are to be tested,which has the ability to remain intact for at least 24 h of waterimmersion.The approximate size shall be 10 10 in.250 250 mm.7.Test Specimens7.1 Samples of tape and adhesives shall be representative of
