1、Designation: D2053 99 (Reapproved 2015)Standard Test Method forColorfastness of Zippers to Light1This standard is issued under the fixed designation D2053; 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 () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the determination of the altera-tion in shade of the textile portion of zippers when exposed tolight, regardl
3、ess 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 used
4、 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-priate
5、 safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

9、tinuous 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 inte
10、ndedend-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
11、 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 from which the disparate test results were ob
12、tained,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 a probability level chosen prior
13、to the testingseries. 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、 collection of proven zippertest methods. They can be used as aids in the evaluation ofzippers without the need for a thorough knowledge of zippers.The enumerated test methods do not provide for the evaluationof all zipper properties. Besides those properties measured bymeans of the enumerated test
18、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 resulting from existi
19、ng unpublished methods requires anintimate and thorough knowledge of zippers.6. Sampling and Test Specimens6.1 Primary Sampling UnitConsider individual containersfrom each shipping carton to be the primary sampling units.6.2 Laboratory Sampling UnitAs a laboratory samplingunit, take at random one zi
20、pper from each primary samplingunit.6.3 Test SpecimensAs a test specimen, take approximatelya 120-mm (4.75-in.) length of the laboratory sample thatconsists of the tape and chain.7. Mounting the Test Specimen7.1 Mount the specimen front face up, as prescribed inAATCC Test Method 16, with approximate
21、ly half the specimencovered 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
22、between them. Consequently, 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 Metho

Report10.1 State that the specimens were tested as directed in theTest Method D2053. Describe the material or product sampled,and the method of sampling
24、 used.10.2 Report the following 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 orAATCCFading
25、Units, as appropriate, 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 r
26、ating scales of color differenceunits, 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
27、 may bedetermined. This test method has no known bias.12.
