United States1structure of the yarns; the construction of the fabrics; and thetype, kind, and amount of finishing material added to the fibers,yarns, or fabric.5.2 The resistance to abrasion is also greatly affected by theconditions of the tests, such as the nature of abrada

    16、nt, variableaction of the abradant over the area of specimen abraded, thetension of the specimen, the pressure between the specimenand abradant, and the dimensional changes in the specimens.5.3 Abrasion tests are all subject to variation due to changesin the abradant during specific tests. The abrad

    17、ant mustaccordingly be discarded at frequent intervals or checkedperiodically against a standard. With disposable abradants, theabradant is used only once or discarded after limited use. Withpermanent abradants that use hardened metal or equivalentsurfaces, it is assumed that the abradant will not c

    18、hangeappreciably in a specific series of tests. Similar abradants usedin different laboratories will not change at the same rate, due todifferences in usage. Permanent abradants may also change dueto pick up of finishing or other material from test fabrics andmust accordingly be cleaned at frequent

    19、intervals. The mea-surement of the relative amount of abrasion may also beaffected by the method of evaluation and may be influenced bythe judgment of the operator.5.4 The resistance of textile materials to abrasion as mea-sured on a testing machine in the laboratory is generally onlyone of several

    20、factors contributing to wear performance ordurability as experienced in the actual use of the material.While “abrasion resistance” (often stated in terms of thenumber of cycles on a specified machine, using a specifiedtechnique to produce a specified degree or amount of abrasion)and “durability” (de

    21、fined as the ability to withstand deteriora-tion or wearing out in use, including the effects of abrasion) arefrequently related, the relationship varies with different enduses, and different factors may be necessary in any calculationof predicted durability from specific abrasion data. Laboratoryte

    22、sts may be reliable as an indication of relative end-useperformance in cases where the difference in abrasion resis-tance of various materials is large, but they should not be reliedupon where differences in laboratory test findings are small. Ingeneral, they should not be relied upon for prediction

    23、 of actualwear-life in specific end uses unless there are data showing thespecific relationship between laboratory abrasion tests andactual wear in the intended end-use.5.5 These general observations apply to all types of fabrics,including woven, nonwoven, and knit apparel fabrics, house-hold fabric

    24、s, industrial fabrics, and floor coverings. It is notsurprising, therefore, to find that there are many different typesof abrasion testing machines, abradants, testing conditions,testing procedures, methods of evaluation of abrasion resis-tance and interpretation of results.5.6 All the test procedur

    25、es and instruments that have beendeveloped for abrasion resistance of fabrics may show a highdegree of variability in results obtained by different operatorsand in different laboratories, however, they represent theprocedures most widely used in the industry. Because there isa definite need for meas

    26、uring the relative resistance toabrasion, this is one of the several procedures that is useful tohelp minimize the inherent variation in results that may occur.5.7 Before definite predictions of fabric usefulness can bedrawn from an abrasion test as made on the rotary platform,double-head (RPDH) abr

    27、ader (Fig. 1), actual end-use trialsshould be conducted and related to the abrasion test. Differenttypes of wear (for example, wear on mens clothing at cuffs,crotch, etc.) may correspond to different ratings of the RPDHtest.5.8 In making a comparison of different fabrics (that is, ofdifferent fibers

    28、, weights, etc.) the RPDH test will not alwaysreveal a difference known to exist when the fabrics are actuallyused. Therefore, end-use trials should be conducted in conjunc-tion with the RPDH abrasion test, at least as a guide for futuretesting of these fabrics.5.9 Uncontrolled manufacturing or fini

    29、shing variations oc-curring within a fabric or within lots of the same style of fabriccan, however, be detected satisfactorily with the RPDH tester.5.10 Because of the conditions mentioned above, techni-cians frequently fail to get good agreement between resultsobtained on the same type of testing i

    30、nstrument both within andbetween laboratories, and the precision of these test methods isuncertain. This test method is accordingly not recommendedfor acceptance testing in contractual agreements betweenpurchaser and supplier because of the poor between-laboratoryprecision of the test method.5.11 If

    31、 there are differences of practical significance 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 statisticalassistance. As a minimum, the test samples used are to be ashomogen

    32、eous as possible, drawn from the material from whichthe disparate test results were obtained, and randomly assignedin equal numbers to each laboratory for testing. The test resultsfrom the two laboratories should be compared using a statis-tical test for unpaired data, at a probability level chosen

    33、priorto the testing series. If bias is found, either its cause must befound and corrected, or future test results must be adjusted inconsideration of the known bias.6.
