Scope1.1 This test method covers the determination of alterationin shade and of staining under conditions similar to thatexperienced in d
3、omestic washing of zipper stringers. This testmethod is applicable to the textile portion of zipper stringersthat utilize tapes made of cotton, linen, or manufacturedorganic fibers, and to combinations thereof.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately

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 s

Significance and Use5.1 Test Method D2057 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 wil
12、l occur.NOTE 1For guidance in evaluating the results of this method, refer toPractice 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 j

16、nificance 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 dra
17、wn 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 statis
18、tical 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.5.3 The method(s) in this standard along with those inD2051, D2052, D205
19、3, D2054, D2058, D2059, D2060,D2061, and D2062 are a collection of proven zipper 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
20、 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 notbeen published either because no practical methods have yetbeen developed or because a valid
21、evaluation of the informa-tion resulting from existing unpublished methods requires anintimate and thorough knowledge of zippers.6.

Number of Specimens9.1 Unless otherwise agreed upon, as when specified in anapplicable material specification, take one zipper at randomfrom each individual container selected for sampling.10. Test Specimen10.1 The test specimen shall consist of approximately 7740mm2(12 in.2) of zipper chai

The specimen need not be acontinuous length.10.2 A 51-mm (2-in.) square of multifiber test cloth No. 10as specified in AATCC Method 61 shall be sewn or stapled tothe stringer length, with the filling stripes running at rightangles to the stringer length. The multifiber test cloth shall beattached

35、of which household detergent is used. Because ofdifferences in water hardness, different detergents may affect shadebecause of varying degrees of deposition from the hard water. However,the depositions would be the same on the entire item into which the zipperwas applied.12.4 Repeat the washing - dr

39、or each multifiber stripe specimen as thegrade on the AATCC Chromatic Transference Scale.15. Precision and Bias15.1 PrecisionAn interlaboratory test and calculation ofcomponents of variance was felt to be inappropriate because ofthe restricted and discontinuous rating scales, the non-linearrelations
40、hips between the rating scales and color differenceunits, the increased variability in color difference units as thetrue value of the ratings decrease, and the restriction of the datafor degree of staining to the cotton portion of the multifiber testfabric. Based on these reasons and on general prac
41、tice in thetrade, a lot or consignment of zippers is generally considered ashaving a rating that is significantly worse than a specified valuewhen a specimen from the lot or consignment has a rating forchange in color that is more than one-half step below thespecified rating on theAATCC Gray Scale f
42、or Color Change orfor degree of staining, a rating that is more than one-half stepbelow the specified rating on the AATCC Chromatic Transfer-ence Scale.15.2 BiasNo justifiable statement can be made on the biasof Test Method D2057 for grading zippers for change in coloror for degree of staining, sinc
