Designation:D206203(Reapproved 2021)Standard Test Methods forOperability of Zippers1This standard is issued under the fixed designation D2062;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 These test methods cover procedures for determiningthe following characteristics of zippers:SectionsOpening and Closing of Zippers14 17Separator Functioning of Zippers18 22Sticking of Zippers at Stops10 131.2 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.1.3 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:2D123 Terminology Relating to TextilesD2050 Terminology Relating to Subassemblies Used in theManufacture of TextilesD2051 Test Method for Durability of Finish of Zippers toLaunderingD2052 Test Method for Colorfastness of Zippers to Dry-cleaningD2053 Test Method for Colorfastness of Zippers to LightD2054 Test Method for Colorfastness of Zipper Tapes toCrockingD2057 Test Method for Colorfastness of Zippers to Laun-deringD2058 Test Method for Durability of Finish of Zippers toDrycleaningD2059/D2059M Test Method for Resistance of Zippers toSalt Spray(Fog)D2060 Test Methods for Measuring Zipper DimensionsD2061 Test Methods for Strength Tests for Zippers3.Terminology3.1 Definitions:3.1.1 For definitions of zipper terms used in these testmethods,refer to Terminology D2050.For definitions of othertextile terminology used in these test methods,refer to Termi-nology D123.4.Significance and Use4.1 The significance of specific tests is discussed in theappropriate sections.4.2 These test methods are considered satisfactory for ac-ceptance testing of commercial shipments of zippers becausethe methods have been used extensively in the trade for thispurpose,even though current estimates of between-laboratoryprecision are quite large in some cases.4.2.1 If there are differences of practical significance be-tween reported test results for two laboratories(or more),comparative test should be performed to determine if there is astatistical bias between them,using competent statistical assis-tance.As a minimum,the test samples should be used that areas homogeneous as possible,that are drawn from the materialfrom which the disparate test results were obtained,and thatare randomly assigned in equal numbers to each laboratory fortesting.Other materials with established test values may beused for this purpose.The test results from the two laboratoriesshould be compared using a statistical test for unpaired data,ata probability level chosen prior to the testing series.If a bias isfound,either its cause must be found and corrected,or futuretest results must be adjusted in consideration of the knownbias.4.3 The method(s)in the standard along with those in TestMethods D2051,D2052,D2053,D2054,D2057,D2058,D2059/D2059M,D2060,and D2061 are a collection of proventest methods.They can be used as aids in the evaluation ofzippers without the need for a thorough knowledge of zippers.The enumerated test methods do not provide for the evaluation1These test methods are under the jurisdiction of ASTM Committee D13 onTextiles and are the direct responsibility of Subcommittee D13.54 on Subassem-blies.The methods were developed in cooperation with the Slide Fastener Assn.,Inc.Current edition approved July 1,2021.Published July 2021.Originally approvedin 1961.Last previous edition approved in 2014 as D2062 03(2014).DOI:10.1520/D2062-03R21.2For 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.1of all zipper properties.Besides those properties measured bymeans of the enumerated test methods there are other proper-ties that may be important for the satisfactory performance ofa zippe
