Designation:D205499(Reapproved 2015)Standard Test Method forColorfastness of Zipper Tapes to Crocking1This standard is issued under the fixed designation D2054;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 degreeof color that may be transferred from the textile tape of zippersof all fibers to other surfaces by rubbing under wet or dryconditions,or both.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 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 TextilesD1776 Practice for Conditioning and Testing TextilesD2050 Terminology Relating to Fasteners and ClosuresUsed with Textiles2.2 AATCC Methods:3Method 8 Colorfastness to Crocking:AATCC Crockmeter MethodAATCC Chromatic Transference Scale3.Terminology3.1 DefinitionsFor definitions of zipper terms used in thisstandard,refer to Terminology D2050.For definitions of othertextile terminology used in this standard,refer to TerminologyD123.4.Summary of Test Method4.1 A specimen of the zipper tape fastened to the base of acrockmeter is rubbed with white crock test cloth under con-trolled conditions.Color transferred to the white test cloth isassessed by a comparison with the AATCC Chromatic Trans-ference Scale.5.Significance and Use5.1 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.5.1.1 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 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.6.Apparatus6.1 Apparatus,as specified in AATCC Test Method 8.6.2 Smooth Cardboard Cards,50 by 200 mm(2 by 8 in.)approximating index card weight.7.Sampling and Test Specimens7.1 Primary Sampling UnitConsider individual containersfrom each shipping carton to be the primary sampling units7.2 Laboratory Sampling UnitAs a laboratory samplingunit,take at random one zipper from each primary samplingunit.7.3 Test SpecimensConsider the laboratory sample as thetest specimen.1This test method is under the jurisdiction ofASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.54 on Subassemblies.This testmethod was developed in cooperation with the Slide Fastener Association,Inc.Current edition approved Feb.1,2015.Published April 2015.Originallyapproved in 1961.Last previous edition approved in 2010 as D2054 99(2010).DOI:10.1520/D2054-99R15.2For 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 8.Mounting the Test Specimen8.1 Bring the specimens to moisture equilibrium for testingin the standard atmosphere for testing textiles as directed inPractice D1776.Preconditioning is not required.9.Procedure9.1 Center the specimen on the base of the crockmeter sothat it rests flatly on the abrasive cloth with its long dimensionin the direction of rubbing.Secure the specimen card and testfor colorfastness to crocking as directed in Section 5.1.2 andsubsequent sections of AATCC Test Method 8.1
