Designation:D205803(Reapproved 2014)Standard Test Method forDurability of Finish of Zippers to Drycleaning1This standard is issued under the fixed designation D2058;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 test method covers the determination of the dura-bility of the enamel or other decorative coating of zippers whensubjected to drycleaning.1.2 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D123 Terminology Relating to TextilesD2050 Terminology Relating to Fasteners and ClosuresUsed with 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-deringD2059 Test Method for Resistance of Zippers to Salt Spray(Fog)D2060 Test Methods for Measuring Zipper DimensionsD2061 Test Methods for Strength Tests for ZippersD2062 Test Methods for Operability of Zippers2.2 AATCC Method:Method 86 Drycleaning:Durability of Applied Designs andFinishes33.Terminology3.1 Definitions:3.1.1 For definitions of zipper terms used in this standard,refer to Terminology D2050.For definitions of other textileterminology used in this standard refer to Terminology D123.4.Summary of Test Method4.1 A specimen is agitated in a solution of solvent and adrycleaning detergent with steel balls to simulate the actionthat occurs in a drycleaning machine.5.Significance and Use5.1 Test Method D2058 is useful for determining the effectof repeated drycleaning on the appearance of the decorativecoating of a zipper.5.2 This test method is considered satisfactory for accep-tance testing of commercial shipments because the method hasbeen used extensively in the trade for acceptance testing.5.2.1 If there are differences of practical significance be-tween reported test results for two laboratories(or more),comparative tests should be performed to determine if there isa statistical bias between them,using competent statisticalassistance.As a minimum,the test samples should be used thatare as homogeneous as possible,that are drawn from thematerial from which the disparate test results were obtained,and that are randomly assigned in equal numbers to eachlaboratory for testing.Other materials with established testvalues may be used for this purpose.The test results from thetwo laboratories should be compared using a statistical testunpaired data,at a probability level chosen prior to the testingseries.If a bias is found,either its cause must be found andcorrected,or future test results must be adjusted in consider-ation of the known bias.5.3 The method(s)in the standard along with those in TestMethods D2051,D2052,D2053,D2054,D2057,D2059,D2060,D2061,and D2062 are a collection of proven testmethods.They can be used as aids in the evaluation of zipperswithout the need for a thorough knowledge of zippers.Theenumerated test methods do not provide for the evaluation ofall 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 zipper.Test methods for measuring those properties have not1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.54 on Subassemblies.Themethod was developed in cooperation with the Slide Fastener Assn.Inc.Current edition approved Feb.1,2014.Published March 2014.Originallyapproved in 1961.Last previous edition approved in 2009 as D2058 03(2009).DOI:10.1520/D2058-03R14.2For referenced ASTM standards,visit the ASTM web site,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 web site.3Technical Manual of the American Association of Textile Chemists andColorists,P.O.Box 12215,Research Triangle Park,NC 27709.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 been published either because no practical methods have yetbeen developed or because a valid evaluation of the informa-tion resulting from existing unpublished methods requires anintimate and thorough knowledge of zippers.6.Sampling6.1 Lot SampleAs a lot sample for acceptance testing,takeat random the number of individual containers from eachshipping
