1、Designation: D 2052 05Standard Test Method forColorfastness of Zippers to Drycleaning1This standard is issued under the fixed designation D 2052; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number i

2、n parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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

3、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

4、; 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 stand

9、g terms are relevant to this standard:colorfastness, drycleaning.3.2 For all other terminology relating to textiles, see Termi-nology D 123.4. Summary of Test Method4.1 A specimen of the zipper stringer, in conjunction withmultifiber test fabric is subjected to drycleaning. The dry-cleaned specimen

10、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 D 2052 is useful

11、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,refer to Practice D 3692.5.2 This test method is

12、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),1This test method is under th

13、e jurisdiction of ASTM 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 Sept. 1, 2005. Published October 2005. Originallyapproved in 1961. Last previou

Box 12215, Research Triangle Park, NC 27709.1Copyright ASTM International, 100 Barr Harbor Drive, PO Box C700, West Conshohocken, PA 19428-2959, United Sparative tests should be performed to determine if their isa statistical bias betwe

16、en 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 m

17、aterials 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 found, either its cause must be found andcorrected, or futur

18、e 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 D 2051, D 2053, D 2054, D 2057, D 2058, D 2059,D 2060, D 2061, and D 2062 are a collection of proven zippertest methods. They can be used as aids in the evaluation o

19、fzippers 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 that may be important for the satisfactory perform

20、ance 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 anintimate and thorough knowledge of zippers.6. Appara

21、tus6.1 The apparatus shall be as specified in Methods D 2724.6.2 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 Fabric No. 10.46.5 Undyed Cotton Twill Cloth, weigh

Sampling7.1 Lot SampleAs a lot sample for acceptance testing,take at random the number of individual containers from eachshipping carton as directed in an applicable material specifi-cation or other agreement between the purchaser and thesupplier. Consider indiv

23、idual 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 in a container to provide a samplingplan with a mea

Consider the zippers as

25、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 Specimen9.1 The test specimen shall consist of appr

26、oximately 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 specimens shall be conditioned for at least4hinthe

27、 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, prepare a bag withinside dimensions of 200 by 100 mm (8

28、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 for Drycleaning D 2724, 10.1 through 10.3.11.3 Re

29、peat 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 textile portion of the specimens for changein col

Precision and Bias14.1 Interlaboratory Test DataAn interlaboratory test wasrun in 1972 using AATCC Method 132 in which randomlydrawn samples of two materials were tested in each of threelaboratories. Each lab

33、oratory used two operators, each ofwhom tested 12 specimens of each material. Calculation ofcomponents of variance was felt to be inappropriate because of4Suitable material is available from Testfabrics, Inc., P.O. Drawer 0, Middlesex,NJ 08846.D2052052the restricted and discontinuous rating scale, t

34、he 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 general practice in the trade, the half-steprating scale h

A lot orconsignment of zippers is generally considered as having arating that is significantly worse than a specified value when aspecimen from the lot or consignment has a rating for changein colo

36、r 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 D 2052 for grading zipper assemblages forchange in color during drycleaning since the true value of thisproperty cannot be esta
