Significance and Use4.1 Upon mutual agreement between the purchaser and thesupplier, woven and knitted products intended for this end useshould meet all of the requirements listed in Table 1 of thisspecification.4.2 It is recognized that for purposes of fashion oraesthetics,
21、the ultimate consumer of articles made from thesefabrics may find acceptable products that do not conform to allof the requirements in Table 1. Therefore, one or more of therequirements listed in Table 1 may be modified by mutualagreement between the purchaser and the supplier.4.2.1 In such cases, a

Perform the tests on theproducts as it reaches the customer. Any “partially finished” or“post-finish” fabrics should be processed in accordance
33、withthe fabric manufacturers instructions.5.4 If the applicable test method does not specify thenumber of specimens, use the procedures in Practice D2905 todetermine the number of specimens per laboratory sample unit.5.4.1 Use a reliable estimate of the variability of individualobservations on simil

Specification Requirements6.1 The properties of institutional and household sheetproducts shall conform to the specification requirements inTable 1 or by mutual agreement between the purchas
36、er and thesupplier.7. Testing For Household 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
37、 Method D5034,using a constant-rate-of-traverse (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 testingmachine may be used. The crosshead speed should be as agreed uponbetween the purch
38、aser and the supplier. There may be no 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 Onl
39、y)Determine thebursting force of knit fabrics in the standard atmosphere fortesting textiles, as directed in Test Method D3786 or TestMethod D3787 as agreed upon between the purchaser and thesupplier.NOTE 3There is no overall correlation between the results obtainedwith the CRT machine equipped with
40、 a bursting attachment and thediaphragm bursting tester. Consequently, these two bursting testers cannotbe used interchangeably. In the case of controversy, the motor-drivendiaphragm tester method (Test Method D3786) shall prevail.NOTE 4The precision of the bursting strength testers has not beenesta
41、blished. The methods are accordingly 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 ofwo
42、ven fabrics as directed in Test Method D1424.NOTE 5If preferred, the use of Test Method D2261 or D2262 ispermitted, with existing requirements as given in this specification. Theremay be no overall correlation between the results obtained with the tonguetear testers and the Elmendorf Tester. Consequ
43、ently, these three testerscannot be used interchangeably. In case of controversy, Test MethodD1424 shall prevail.7.1.4 PillingDetermine pilling as directed in Test MethodD3512 with a test time (run time) of 30 min.7.1.5 Dimensional ChangeDetermine the maximum di-mensional change after five launderin
