Designation:D205205(Reapproved 2015)Standard Test Method forColorfastness of Zippers to Drycleaning1This standard is issued under the fixed designation D2052;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 change inshade and of staining of zipper stringers under drycleaningconditions.This test method is applicable to the textile portionof zipper stringers of all materials.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as the standard.Within the text,the inch-pound units are shown in parentheses.The valuesstated in each system are not exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in nonconformancewith this test method.1.3 This standard does not purport to address all of thesafety problems associated with its use.It is the responsibilityof whoever uses this standard to consult and 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 toLaunderingD2053 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 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 ZippersD2724 Test Methods for Bonded,Fused,and LaminatedApparel FabricsD3692 Practice for Selection of Zippers for Care-LabeledApparel and Household Furnishings2.2 AATCC Methods:Evaluation Procedure 1,AATCC Gray Scale for ColorChange3Evaluation Procedure 3,AATCC Chromatic TransferenceScale33.Terminology3.1 For all terminology related to D13.54,Subassemblies,refer to Terminology D2050.3.1.1 The following terms are relevant to this standard:colorfastness,drycleaning.3.2 For all other terminology relating to textiles,see Termi-nology D123.4.Summary of Test Method4.1 A specimen of the zipper stringer,in conjunction withmultifiber test fabric is subjected to drycleaning.The dry-cleaned specimen is compared with an original specimen(see10.1)and any change in color of the specimen or staining of themultifiber test cloth is then assessed using the AATCC GrayScale for Color Change or theAATCC Chromatic TransferenceScale,as appropriate.5.Significance and Use5.1 Test Method D2052 is useful for testing to determine ifthe degree of alteration in shade is satisfactory for the intendedend-use and for determining if unacceptable staining of colorinto adjacent fabric will occur.NOTE1For guidance in evaluating the results of this test method,referto Practice D3692.5.2 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.1This 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.1,2015.Published April 2015.Originallyapproved in 1961.Last previous edition approved in 2010 as D2052 05(2010).DOI:10.1520/D2052-05R15.2For 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.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 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 their 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 test forunpaired data,at probability level chosen prior t
