Standard Test Method for Durability of Finish of Zippers to Laundering
SIGNIFICANCE AND USE
Test Method D 2051 is useful for testing to determine the effect of repeated laundering on the appearance of the decorative coating of a zipper.
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 labortories (or more), comparative test should be performed to determine if there is a statistical bias between them, using compentent 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.
The test method(s) in the standard along with those in Test Methods D 2052, D 2053, D 2054, D 2057, D 2058, D 2059, D 2060, D 2061, and D 2062 are a collection of proven 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 no practical methods have yet been developed or because a valid evaluation of the information resulting from existing unpublished methods requires an intimate ...
SCOPE
1.1 This test method covers the determination of the durability of the enamel or other decorative coating of a zipper when subjected to laundering.
1.2 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.
