1、Designation: D2054 99 (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 re
2、vision. 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 al
3、l 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 equivalent
4、s; 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 t
5、his standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

8、C 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 rep
9、orted 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 fr
10、om 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
11、 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.
