ASTM D2057-05(2015)

Standard Test Method for Colorfastness of Zippers to Laundering

SIGNIFICANCE AND USE
5.1 Test Method D2057 is useful for testing to determine if the degree of alteration in shade is satisfactory for the intended end-use and for determining if unacceptable staining of color into adjacent fabric will occur.
Note 1: For guidance in evaluating the results of this method, refer to Practice D3692.  
5.2 This test method is considered satisfactory for acceptance testing of commercial shipments because the method has been used extensively in the trade for acceptance testing.  
5.2.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if their is a statistical bias between them, using competent statistical assistance. As a minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.  
5.3 The method(s) in this standard along with those in D2051, D2052, D2053, D2054, D2058, D2059, D2060, D2061, and D2062 are a collection of proven zipper test methods. They can be used as aids in the evaluation of zippers without the need for a thorough knowledge of zippers. The enumerated test methods do not provide for the evaluation of all zipper properties. Besides those properties measured by means of the enumerated test methods there are other properties that may be important for the satisfactory performance of a zipper. Test methods for measuring those properties have not been published either because...
SCOPE
1.1 This test method covers the determination of alteration in shade and of staining under conditions similar to that experienced in domestic washing of zipper stringers. This test method is applicable to the textile portion of zipper stringers that utilize tapes made of cotton, linen, or manufactured organic fibers, and to combinations thereof.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. combining values from the two systems may result in nonconformance with this test method.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

4. Summary of Test Method
4.1 Specimens in contact with a multifiber test cloth are laundered in home laundry and drying equipment, with or without
bleach, under appropriate temperature conditions to produce the effect of home laundering on zipper color. The alteration in shade
and the degree of staining of the multifiber test cloth are graded by reference to the AATCC Gray Scale or to the AATCC Chromatic
Transference Scale, as appropriate.
5. Significance and Use
5.1 Test Method D2057 is useful for testing to determine if the degree of alteration in shade is satisfactory for the intended
end-use and for determining if unacceptable staining of color into adjacent fabric will occur.
NOTE 1—For guidance in evaluating the results of this method, refer to Practice D3692.
5.2 This test method is considered satisfactory for acceptance testing of commercial shipments because the method has been
used extensively in the trade for acceptance testing.
5.2.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative
tests should be performed to determine if their is a statistical bias between them, using competent statistical assistance. As a
minimum, the test samples should be used that are as homogeneous as possible, that are drawn from the material from which the
disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials

D2062 are a collection of proven zipper test methods. They can be used as aids in the evaluation of zippers without the need for
a thorough knowledge of zippers. The enumerated test methods do not provide for the evaluation of all zipper properties. Besides
those properties measured by means of the enumerated test methods there are other properties that may be important for the

practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished
methods requires an intimate and thorough knowledge of zippers.
