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 will occur.NOTE 1For guidance

12、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.5.2.1 If there are differences of practical significance be

As a minimum, the test samples should be used thatare as homogeneous as possible, that are drawn from thematerial from which

17、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

18、 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, D2053, D2054, D2058, D2059, D2060,D

20、 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 evaluation of the informa-tion

Precision and Bias15.1 PrecisionAn

40、 interlaboratory test and calculation ofcomponents of variance was felt to be inappropriate because ofthe restricted and discontinuous rating scales, the non-linearrelationships between the rating scales and color differenceunits, the increased variability in color difference units as thetrue value

41、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 practice in thetrade, a lot or consignment of zippers is generally considered ashaving a rating that is significantly worse than a

42、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 for Color Change orfor degree of staining, a rating that is more than one-half stepbelow the specified rating on the AATCC Chrom
