1、Designation: D 2053 99 (Reapproved 2004)Standard Test Method forColorfastness of Zippers to Light1This standard is issued under the fixed designation D 2053; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision
2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the alter-ation in shade of the textile portion of zippers when exposed tolight, rega
3、rdless of the materials of manufacture.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 equivalents; therefore, eachsystem shall be u
4、sed 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 this standard to establish appro-pri
5、ate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

For definitions of othertextile terminology used in this standard, refer to TerminologyD 123.4. Summary of Test Method4.1 A specimen of zipper tape and chain is exposed tocontinuous
9、artificial light for a predetermined period of expo-sure. Fading of the specimen is evaluated and rated by meansof the AATCC Gray Scale for Color Change.5. Significance and Use5.1 This test method is useful in determining if the loss ofcolor due to light exposure is satisfactory for the intendedend-
10、use.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-tween reported test results for two laboratories (or more),c
11、omparative 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 from which the disparate test results were obtained,a
12、nd 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 a probability level chosen prior to the t
13、estingseries. If a bias is found, either its cause must be found and1This test method is under the jurisdiction of ASTM Committee D13 on Textilesand is the direct responsibility of Subcommittee D13.54 on Subassemblies.

17、st methods. They can be used as aids in theevaluation of zippers without the need for a thorough knowl-edge of zippers. The enumerated test methods do not providefor the evaluation of all zipper properties. Besides thoseproperties measured by means of the enumerated test methodsthere are other prope
18、rties that may be important for thesatisfactory performance of a zipper. Test methods for measur-ing those properties have not been published either because nopractical methods have yet been developed or because a validevaluation of the information resulting from existing unpub-lished methods requir

Sampling and Test Specimens6.1 Primary Sampling UnitConsider individual contain-ers from each shipping carton to be the primary sampling units.6.2 Laboratory Sampling UnitAs a laboratory samplingunit, take at random one zipper from each primary samp
20、lingunit.6.3 Test SpecimensAs a test specimen, take approxi-mately a 120-mm (4.75-in.) length of the laboratory samplethat consists of the tape and chain.7. Mounting the Test Specimen7.1 Mount the specimen front face up, as prescribed inAATCC Test Method 16, with approximately half the specimencover
21、ed and the remainder exposed.8. Procedure8.1 Test the specimen for colorfastness as directed inAATCC Test Method 16.NOTE 1There are distinct differences in spectral distribution betweenthe various types of machines listed in AATCC Test Method 16, with nooverall correlations between them. Consequentl
22、y, these machines cannotbe used interchangeably. In case of controversy, results obtained with thewater-cooled Xenon-arc machine listed in Option E shall prevail.9. Interpretation of Results9.1 Interpret the results of the test on the specimens asdirected in AATCC Test Method 16 for the selected opt
23、ion, asappropriate, using the Classification Based on a SpecifiedNumber of Standard Fading Hours or AATCC Fading Units.10. Report10.1 State that the specimens were tested as directed in theTest Method D 2053. Describe the material or productsampled, and the method of sampling used.10.2 Report the fo
24、llowing information for the laboratorysampling unit and for the lot as applicable to a materialspecification or contract order.10.2.1 Specify the AATCC Test Method 16 option used,10.2.2 Number of specimens tested,10.2.3 Degree of fading as standard fading hours or AATCCFading Units, as appropriate,
25、and10.2.4 Degree of fading for each specimen as the appropri-ate grade on the AATCC Gray Scale for Color Change.11. Precision and Bias11.1 PrecisionIt is not possible to specify the precision ofthis test method because of the restricted and nonlinearrelationships between the rating scales of color d
26、ifferenceunits, and the increased variability in color difference units asthe true value of ratings decrease.11.2 BiasThe procedure of this test method produces atest value that can be defined only in terms of a test method.There is no independent, referee method by which bias may bedetermined. This
27、 test method has no known bias.12.
