1、Designation: D2052 05 (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 revi

2、sion. 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. Th

3、is 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 ex

4、act 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

5、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.

Summary of Test Method4.1 A specimen of the zipper stringer, in conjunction withmultifiber test fabric is subjected to drycleaning

10、. 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 Te

11、st 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.NOTE 1For guidance in evaluating the results of this test method, referto Practice D3692

12、.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 of ASTM Committee D13 on Textilesand is the direct responsibility of Subcommitt

United States15.2.1 If there are differences of practical significance be-tween reported test results for two laboratories (or more),comparative tests should b

16、e 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 assi

17、gned 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 to the testingseries. If a bias is

18、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 this standard along with those in TestMethods D2051, D2053, D2054, D2057, D2058, D2059,D2060, D2061, and D2062 are a collection of proven zippertest me

19、thods. 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 evaluationof all zipper properties. Besides those properties measured bymeans of the enumerated test methods there are other proper-ties

20、 that may be important for the satisfactory performance ofa zipper. Test methods for measuring those properties have notbeen published either because no practical methods have yetbeen developed or because a valid evaluation of the informa-tion resulting from existing unpublished methods requires ani

21、ntimate and thorough knowledge of zippers.6. Apparatus6.1 The apparatus shall be as specified in Methods D2724.6.2 AATCC Chromatic Transference Scale, as specified inAATCC Evaluation Procedure 3.6.3 Gray Scales for Color Change, as specified in AATCCEvaluation Procedure 1.6.4 AATCC Multifiber Test F

Sampling7.1 Lot SampleAs a lot sample for acceptance testing, takeat random the number of individual containers from eachshipping carton as directed in an applicable material specifi-cation or other agreement bet

23、ween the purchaser and thesupplier. Consider individual containers from each shippingcarton to be the primary sampling units.NOTE 2An adequate specification or other agreement between thepurchaser and supplier requires taking into account the variability betweenshipping cartons and between zippers i

24、n a container to provide a samplingplan with a meaningful producers risk, consumers risk, acceptablequality level, and limiting quality level.7.2 Laboratory Sample and Test SpecimensAs a labora-tory sample for acceptance testing, take the number of zippersspecified in Section8 at random from each co

25、ntainer in the lotsample. Consider the zippers as both the laboratory sample andthe test specimens.8. Number of Specimens8.1 Unless otherwise agreed upon, as when specified in anapplicable material specification, take one zipper at randomfrom each individual container selected for sampling.9. Test S

26、pecimen9.1 The test specimen shall consist of approximately 40 cm2(6.4 in.2) of zipper stringer taken from each zipper sample. Thespecimen need not be a continuous length.9.2 A duplicate specimen shall be prepared and held forcomparison in evaluating the results of the test.10. Conditioning10.1 The

27、specimens shall be conditioned for at least4hinthe standard atmosphere for testing textiles prior to beingsubjected to the drycleaning procedure. Preconditioning is notnecessary.11. Procedure11.1 UsingAATCC multifiber test fabric No. 10 for one sideand undyed cotton twill cloth for the other, prepar

28、e a bag withinside dimensions of 200 by 100 mm (8 by 4 in.) by sewing thetwo superimposed fabrics around three sides. Place the speci-men flatly inside the bag. Close the bag by any convenientmeans such as sewing or stapling the open side.11.2 Dryclean the specimen in the bag as directed inProcedure

29、 for Drycleaning D2724, 10.1 through 10.3.11.3 Repeat the drycleaning procedure through two addi-tional cycles, for a total of three cycles. Remove the specimensfrom the specimen bag and evaluate for color change andstaining as directed in Section 12 of this test method.12. Evaluation12.1 Grade the

Precision and Bias14.1 Interlaboratory Test DataAn interlaboratory test wasrun in 1972 using AATCC Method 132 in which randomly4Suitable material is available f

Each laboratory used two operators, each ofwhom tested 12 specimens of each material. Calculation ofcomponents of variance was felt to be inappropriate be

34、cause ofthe restricted and discontinuous rating scale, the nonlinearrelationship between the rating scale and color difference unitsand the increased variability in color difference units as the truevalue of the ratings decrease.14.2 PrecisionBased on the observations described in14.1 and on long ge

35、neral practice in the trade, the half-steprating scale has been found to be satisfactory for determiningthe acceptability or non-acceptability of a given lot. A lot orconsignment of zippers is generally considered as having arating that is significantly worse than a specified value when aspecimen fr

36、om the lot or consignment has a rating for changein color that is more than one-half step below the specifiedrating on the AATCC Gray Scale for Color Change.14.3 BiasNo justifiable statement can be made on the biasof Test Method D2052 for grading zipper assemblages forchange in color during dryclean
