Designation:D133710Standard Practice forStorage Life of Adhesives by Viscosity and Bond Strength1This standard is issued under the fixed designation D1337;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 practice describes a laboratory method by whichthe storage life of an adhesive may be measured usingviscosity,adhesive strength,or a combination thereof.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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D618 Practice for Conditioning Plastics for TestingD897 Test Method for Tensile Properties of Adhesive BondsD906 Test Method for Strength Properties of Adhesives inPlywood Type Construction in Shear by Tension LoadingD907 Terminology of AdhesivesD1002 Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Ten-sion Loading(Metal-to-Metal)D1084 Test Methods for Viscosity of Adhesives2.2 Other Standard:3ISO 2555 PlasticsResins in the liquid state or as emulsionsor dispersionsDetermination of apparent viscosity bythe Brookfield Test method3.Terminology3.1 DefinitionsMany terms in this practice are defined inTerminology D907.4.Significance and Use4.1 This practice may be used to determine the storage lifeof any adhesive where this information is required.4.2 This practice is intended to determine whether thestorage life conforms to the minimum specified storage liferequired of an adhesive by viscosity tests(Procedure A)or bybond strength tests(Procedure B),or by both.It does so byproviding results before and after a set of standard conditionsthat simulate storage life.The determination of what therequirements for percentage of the original property retained orthe minimum value for a property is found in the relevantmaterial specification,or as agreed between manufacturer anduser.PROCEDURE AVISCOSITY TEST5.Apparatus5.1 ViscometerUse the apparatus as described in ISO2555.5.2 Controlled-Temperature Chamber,capable of maintain-ing temperature to 63C(65F),to provide temperaturestorage conditions.6.Storage of Adhesive6.1 Store the adhesive and all its components,if there areany,in their original and unopened containers when thecontainer is approximately litre(or quart)size.When theadhesive is supplied in larger containers,the desired number ofsamples is withdrawn from the large container.In this lattercase,the size,type of closure,and nature(such as glass,steel,or tin-coated steel)of the small storage container is agreedupon by the purchaser and the manufacturer.6.2 For storage temperature,use any one of the standardtemperatures specified in Practice D618.The time of storage isany time agreed upon by the purchaser and the manufacturer.Ifthe effect of storage time is desired,it is suggested that at leastthree quantities of the adhesive be stored under the prescribedconditions,and tested at various intervals of time.Use aseparate,unopened container at each such test.7.Conditioning7.1 Condition all containers after storage at 23 6 3C(73.46 5F)before opening.If the adhesive consists of two or more1This practice is under the jurisdiction of ASTM Committee D14 on Adhesivesand is the direct responsibility of Subcommittee D14.10 on Working Properties.Current edition approved Nov.1,2010.Published December 2010.Originallyapproved in 1954.Last previous edition approved in 2004 as D1337 04.DOI:10.1520/D1337-10.2For 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.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 components,blend the components in accordance with theinstructions from the manufacturer,and again adjust thetemperature to 23 6 3C,if required.NOTE1Contact the adhesive manufacturer for recommendationswhen working with moisture sensitive materials or for details concerningspecific viscosity measurements.8.Procedure8.1 Measure the viscosity on both the original adhesive asreceived,and on the adhesive after being subjected to storage.Test the adhesive in either its original container or aftertransferring into a more suitable container.9.Report9.1 Report the following information:9.1.
