1、Designation: D 2058 03Standard Test Method forDurability of Finish of Zippers to Drycleaning1This standard is issued under the fixed designation D 2058; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n

2、umber 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 dura-bility of the enamel or other decorative coating of zippers whensubjected to dryc

3、leaning.1.2 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 safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Refe

7、refer to Terminology D 123.4. Summary of Test Method4.1 A specimen is agitated in a solution of solvent and adrycleaning detergent with steel balls to simulate the actionthat occurs in a drycleaning machine.5. Significance and Use5.1 Test Method D 2058 is useful for determining the effectof repeated

8、 drycleaning on the appearance of the decorativecoating of a zipper.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

9、 be-tween reported test results for two laboratories (or more),comparative tests should be performed to determine if there isa statistical bias between them, using competent stasticalassistance. As a minimum, the test samples should be used thatare as homogeneous as possible, that are drawn from the

10、material from 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 testu

11、npaired 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.5.3 The method(s) in the standard along with those in TestMethods D 2051, D 2052, D 205

12、3, D 2054, D 2057, D 2059,D 2060, D 2061, and D 2062 are a collection of proven testmethods. They can be used as aids in the evaluation of zipperswithout the need for a thorough knowledge of zippers. Theenumerated test methods do not provide for the evaluation ofall zipper properties. Besides those

13、properties measured bymeans of the enumerated test 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 yet1This test method is under the juri

14、sdiction of ASTM Committee D13 on Textiles,and is the direct responsibility of Subcommittee D13.54 on Subassemblies. Themethod was developed in cooperation with the Slide Fastener Assn.

17、from existing unpublished methods requires anintimate and thorough knowledge of zippers.6. Sampling6.1 Lot SampleAs a lot sample for acceptance testing,take at random the number of individual containers from eachshipping carton as directed in an applicable material specifi-cation or other agreement

18、between the purchaser and thesupplier. Consider individual containers from each shippingcarton to be the primary sampling units.NOTE 1An adequate specification or other agreement between thepurchaser and supplier requires taking into account the variability betweenshipping cartons and between zipper

19、s in a container to provide a samplingplan with a meaningful producers risk, consumers risk, acceptablequality level, and limiting quality level.6.2 Laboratory Sample and Test SpecimensAs a labora-tory sample for acceptance testing, take at random two zippersfrom each container in the lot sample. Co

20、nsider the zippers asboth the laboratory samples and the test specimens.7. Test Specimen7.1 The test specimen shall consist either of a completelyassembled zipper or a length of chain. In either case, the lengthshall not be greater than 254 mm (10 in.). In the case of acompletely assembled zipper th

21、at is longer than 254 mm, thespecimen may be made up by cutting out and removing thecentral portion of the chain, and then securely attaching the cutends together, using suitable noncorrosive materials such assewing thread or stainless steel staples. If it is desired to test theentire length of a lo

22、ng zipper, it should be cut into parts 254mm or less in length and those parts tested separately.8. Conditioning8.1 No special environmental conditions are required.9. Procedure9.1 Test each specimen as directed in AATCC TestMethod 86, except air dry only rather than hot press thespecimen.10. Interp

23、retation of Results10.1 Interpret the results of the tests on specimens byvisually examining the chain and components for exposed basemetal and compare observations to samples illustrating anacceptable degree of coating loss as agreed upon between thepurchaser and the supplier.11. Report11.1 State t

24、hat the specimens were tested as directed inASTM Test Method D 2058. Describe the material or productsampled, and the method of sampling used.11.2 Report the following information:11.2.1 Number of specimens tested, and11.2.2 Number of specimens equal to or not equal to theagreed upon standard.12. Pr

25、ecision and Bias12.1 No justifiable statistical statement can be made oneither the precision or the bias of the procedures in ASTM TestMethod D 2058 for testing coating resistance to abrasion indrycleaning, since the method can be used only to secureinformation concerning the conformance of a specim
