Designation:D5570/D5570M10(Reapproved 2022)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,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Documents2.1 ASTM Standards:2D644 Test Method for Moisture Content of Paper andPaperboard by Oven Drying(Withdrawn 2010)3D996 Terminology of Packaging and Distribution Environ-mentsD1974 Practice for Methods of Closing,Sealing,and Rein-forcing Fiberboard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.1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.27 on FiberboardShipping Containers,Containerboard and Related Structures and Materials.Current edition approved April 15,2022.Published April 2022.Originallyapproved in 1994.Last previous edition approved in 2015 as D5570 10(2015).DOI:10.1520/D5570_D5570M-10R22.2For 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 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.16.2 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 0.00
