Significance and Use4.1 Upon mutu

20、al 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 or aesthet-ics, the ultimate consumer of articles made from these fabri

21、csmay 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 purchaser and the supplier.4.2.1 In such cases, any references to the specification shallspecify that: “

22、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, the requirements listed in Table 1 are intended tobe used as a guide only. As noted in 4.2, ultimat

23、e 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 thespecified test methods.

31、Sampling5.1 Acceptance Testing LotUnless there is prior agree-ment, consider as a lot for acceptance testing all material of asingle item as a single shipment.5.2 Lot Samples and Laboratory SamplesFor acceptancetesting, take lot samples and laboratory samples as directed ineach of the applicable tes

32、t methods.5.3 SpecimensTake the number of specimens directed ineach of the applicable test methods. Perform the tests on theproducts as it reaches the customer. Any “partially finished” or“post-finish” fabrics should be processed in accordance withthe fabric manufacturers instructions.5.4 If the app

33、licable test method does not specify thenumber of specimens, use the procedures in Practice D 2905 todetermine the number of specimens per laboratory sample unit.5.4.1 Use a reliable estimate of the variability of individualobservations on similar materials in the users laboratory,5.4.2 A 95 % proba

35、otential specimens from that laboratory samplingunit.6. Specification Requirements6.1 The properties of institutional and household sheetproducts shall conform to the specification requirements inTable 1 or by mutual agreement between the purchaser and thesupplier.7. Testing For Household and Instit

36、utional 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-traverse (CRT)

37、 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 overallcorre

38、lation 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 fabrics in th

39、e standard atmosphere fortesting textiles, as directed in Test Method D 3786 or TestMethod D 3787 as agreed upon between the purchaser and thesupplier.NOTE 3There is no overall correlation between the results obtainedwith the CRT machine equipped with a bursting attachment and thediaphragm bursting

40、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 not recomme

41、nded 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 Method D 1424.NO

42、TE 5If preferred, the use of Test Method D 2261 or D 2262 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. Consequently, these three testerscannot be used inte

43、rchangeably. 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 permanentlyattached care label

44、 instructions and as directed in AATCCMethod 135 for household use or AATCC Method 96 forinstitutional use as agreed upon between the purchaser and thesupplier.7.1.5.1 The wash conditions and drying procedure shall beas specified by the seller when using AATCC Method 135 forhousehold products or AAT

45、CC Method 96 for institutionalproducts.7.1.5.2 When chlorine bleach is to be used, introduce onecup of any liquid chlorine household bleach containing 5.25 %sodium-hypochlorite (5.0 % available chlorine) into the washerin the manner directed on the bleach container. When non-chlorine bleach is to be

46、 used, introduce it into the washer in theamount and manner directed on the bleach container.NOTE 6Nondurable press items can be flat bed pressed after tumbledrying to eliminate wrinkles before measuring.7.1.6 Fabric AppearanceDetermine the smoothness ap-pearance of non-flannel fabric products after

47、 five launderingsas directed in Test V-A of AATCC Method 124 unlessotherwise agreed upon between the purchaser and the supplier.7.1.7 Bow and SkewnessBefore and after laundering,determine the bias of the sheeting fabrics as directed in MethodD 3882 or by mutual agreement between the purchaser and th

48、esupplier.7.1.8 Colorfastness:7.1.8.1 LaunderingDetermine the colorfastness to laun-dering as directed in Test 4-A of AATCC Method 61 unlessotherwise agreed upon between the purchaser and the supplier.Use Multifiber Test Fabric No. 105, to determine the stainingcharacteristics.NOTE 7For all unbleach

49、able items, Test 3-A will be used.5Multifiber Test Fabric, No. 10 is available from Test Fabrics, Inc., P.O. Box420, Middlesex, NJ 08841.D54310837.1.8.2 CrockingDetermine colorfastness to dry and wetcrocking as directed in AATCC Method 8 for solid shades andAATCC Method 116 for prints or as agreed upon between thepurchaser and the supplier.7.1.8.3 LightDetermine colorfastness to light as directedin AATCC Method 16 Option 1 or Option 3.NOTE 8In case of controversy,AATCC TM16, Option 3 shall prevail.7.1.8.4 PerspirationDetermine colorfastness to p
