20、at for purposes of fashion or aesthet-ics, the ultimate consumer of articles made from these fabricsmay find acceptable products that do not conform to all of therequirements in Table 1. Therefore, one or more of therequirements listed in Table 1 may be modified by mutualagreement between the purcha
21、ser and the supplier.4.2.1 In such cases, any references to the specification shallspecify that: “This product meets ASTM Specification _except for the following characteristic(s).”4.3 Where no prepurchase agreement has been reachedbetween the purchaser and the supplier, and in case ofcontroversy, t
22、he requirements listed in Table 1 are intended tobe used as a guide only. As noted in 4.2, ultimate consumerdemands dictate varying performance parameters for anyparticular product.4.4 The uses and significance of particular properties andtest methods are discussed in the appropriate sections of the

Testing For Househol
35、d and Institutional Use7.1 Test MethodsFabricThe physical and colorfastnessproperties of the fabrics in the sheet products shall be evaluatedas directed as follows:7.1.1 Breaking ForceDetermine the breaking force asdirected in the grab test procedure of Test Method D 5034,using a constant-rate-of-tr
36、averse (CRT) tensile testing machinewith the speed of the pulling jaw at 300 6 10 mm/min (12 60.5 in./min).NOTE 2If preferred, a constant-rate-of-extension (CRE) tensile test-ing machine may be used. The crosshead speed should be as agreed uponbetween the purchaser and the supplier. There may be no
37、overallcorrelation between the results obtained with the CRT machine and withthe CRE machine. Consequently, these two breaking load testers cannot beused interchangeably. In case of controversy, the CRT method shallprevail.7.1.2 Bursting Force (Knit Fabrics Only)Determine thebursting force of knit f

39、gm bursting tester. Consequently, these two bursting testers cannotbe used interchangeably. In the case of controversy, the motor-drivendiaphragm tester method (Test Method D 3786) shall prevail.NOTE 4The precision of the bursting strength testers has not beenestablished. The methods are accordingly
40、 not recommended for accep-tance testing unless preceded by an interlaboratory check in the labora-tories of the purchaser and the supplier, using randomized replicatespecimens of the material to be evaluated.7.1.3 Tear ResistanceDetermine the tear resistance ofwoven fabrics as directed in Test Meth

Theremay be no overall correlation between the results obtained with the tonguetear testers and the Elmendorf Tester. Consequently, these three testerscannot
42、 be used interchangeably. In case of controversy, Test MethodD 1424 shall prevail.7.1.4 PillingDetermine pilling as directed in Test MethodD 3512 with a test time (run time) of 30 min.7.1.5 Dimensional ChangeDetermine the maximum di-mensional change after five launderings following permanentlyattach
