15、d satisfactory for ac-ceptance testing of commercial shipments because the testmethods have been used extensively in the trade for thispurpose, and because current estimates of between-laboratoryprecision are acceptable in most cases.4.2.1 In case of a dispute arising from differences inreported tes

16、t results when using Test Methods D2060 foracceptance testing of commercial shipments, the purchaser andthe supplier should conduct comparative tests to determine ifthere is a statistical bias between their laboratories. Competentstatistical assistance is recommended for the investigation ofbias. As

17、 a minimum, the two parties should take a group of testspecimens that are as homogeneous as possible and that arefrom a lot of material of the type in question. The testspecimens should then be randomly assigned in equal numbersto each laboratory for testing. The average results from the twolaborato

18、ries should be compared using Students t-test forunpaired data and an acceptable probability level chosen by thetwo parties before the testing is begun. If a bias if found, eitherits cause must be found and corrected or the purchaser and thesupplier must agree to interpret future test results in the

19、 light ofthe known bias.4.3 The test method(s) in these test methods, along withthose in Test Methods D2051, D2052, D2053, D2054, D2057,D2058, D2059, D2061, and D2062, are a collection of proventest methods. They can be used as aids in the evaluation ofzippers without the need for a thorough knowled

20、ge of zippers.The enumerated test methods do not provide for the evaluationof all zipper properties. Besides those 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 thos

21、e properties have notbeen published either because no practical methods have yetbeen developed or because a valid evaluation of the informa-tion resulting from existing unpublished methods requires anintimate and thorough knowledge of zippers.5. Sampling5.1 Lot SampleAs a lot sample for acceptance t

22、esting,take at random the number of individual containers from eachshipping carton as directed in an applicable material specifi-cation or other agreement between the purchaser and thesupplier. Consider individual containers from each shippingcarton to be the primary sampling units.NOTE 1An adequate

23、 specification or other agreement between thepurchaser and supplier requires taking into account the variability betweenshipping cartons and between zippers in a container to provide a samplingplan with a meaningful producers risk, consumers risk, acceptablequality level, and limiting quality level.

24、5.2 Laboratory Sample and Test SpecimensAs a labora-tory sample for acceptance testing, take the number of zippersspecified in Section 7 at random from each container in the lotsample. Consider the zippers as both the laboratory sample andthe test specimens.6. Test Specimen6.1 The test specimen shal

25、l consist of a completely as-sembled zipper or length of chain.7. Number of Specimens7.1 All Properties Except Slider Mouth WidthTake anumber of zippers per individual container from each shippingcarton such that the user may expect at the 90 % probabilitylevel that the test result for an individual

26、 container is no morethan the amounts shown in Table 1, above or below the trueaverage for the individual container.

Conditioning8.1 For tests made as directed in Sections 12, 18, 37, 41, and49, bring the specimens to moisture equilibrium for testing in

37、the standard atmosphere for testing textiles as directed inPractice D1776. Preconditioning is not required.8.2 For tests made as directed in Sections 25 and 31,specimens need not be preconditioned nor conditioned.LENGTH OF ZIPPER OR PARTS9. Summary of Test Method9.1 The chain or zipper is placed on

38、a flat surface and, withthe aid of a suitable scale, the length of the zipper or desiredzipper part is determined.10. Significance and Use10.1 These measurements are useful in determining con-formance with a purchasing specification and suitability forend use products using zippers.11. Apparatus11.1

39、 Scale, graduated in 0.5 mm or164 in.12. Procedure12.1 Length of Completely Assembled ZipperPlace theclosed zipper flat on a horizontal working surface withouttension, aligning the chain over a straight reference line on theworking surface. Make marks on the working surface corre-sponding to the zip

40、per extremities. Remove the zipper and,using the scale, measure the distance between the marks to thenearest 1.0 mm or132 in.NOTE 2For the bottom end, the zipper extremities are the bottom ofthe bottom stop or interlocking element for a nonseparable zipper. Thebottom end of a separable zipper is the

41、 lowermost tape or reinforcing tapebut not the overhang of the fixed retainer. For the top end, the zipperextremities are the top of the top stop, or top of the last element, whicheveris the extreme for both nonseparable and separable zippers.12.2 Length of ChainPlace the closed chain, withouttensio

42、n, flat on a horizontal working surface, aligning the chainover a straight reference line on the working surface. Place thescale on one stringer flush alongside the outer edge of theinterlockable elements or the outer edge of the bead if the beadextends beyond the elements. Measure the distance betw

43、eenthe extreme ends of the chain to the nearest 1 mm or132 in.12.3 Length of Tape EndPlace the closed zipper, withouttension, flat on a horizontal working surface, aligning the chainover a straight reference line on the working surface. Place theend of the scale against the outermost surface of the

44、outermoststationary component. Measure to the nearest 1.0 mm or132 in.the tape end length along the cord to the outermost point of thepinked or straight-cut edge. In a case where the lengths of thetape ends on the two stringers are different, measure the lengthof the shorter tape end. This test meth

45、od is not applicable totape ends that are cut or pinked on a diagonal in excess of 5in either direction.12.4 Effective Length of Opening, Completely AssembledZipperPlace the closed zipper, without tension, flat on ahorizontal working surface, aligning the chain over a straightreference line on the w

46、orking surface. With a sharp-pointedpencil, make a reference mark even with the top of the slider.Move the slider to the extreme open position and make anotherreference mark even with the top of the slider. Measure thedistance between the marks to the nearest 1.0 mm or132 in.This test method is not

47、applicable to separable zippers.13. Report13.1 State that the specimens were tested as directed inSections 9-14 of Test Methods D2060. Describe the material orproduct sampled and the method of sampling used.13.2 Report the following information:13.2.1 The specific property (or properties) measured,1

48、3.2.2 Number and description, of specimens tested, and13.2.3 Measured length of each specimen.14. Precision and Bias14.1 PrecisionSee Section 53.14.1.1 Precision of the test method is related to the care withwhich the operator reads the 1.0-mm (132-in.) increments onthe scale. The test method, thoug

49、h employing measurement ofa variable, is really descriptive rather than quantitative. The testmethod has been found satisfactory in commercial use fordetermining conformity to an established specification.14.2 BiasThe procedure in Test Methods D2060 formeasuring the length of zipper parts has no known bias.D2060 00 (2010)3TAPE WIDTH15.
