2、the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This performance specification covers the performancerequirements for woven, knitted, or flocked fabrics t

It is theresponsibility of th
4、e user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use4.1 Fabrics intended for this end-use should meet all of therequirements listed in Table
14、1.4.2 It should be recognized that fabrics can be producedwith an almost infinite number of construction variables (forexample, type of fibers, percentage of fibers, yarn twist, yarnnumber, warp and pick count, chemical and mechanical fin-ishes). Additionally, fashion or aesthetics dictate that theu
15、ltimate consumer may find acceptable articles made fromfabrics that do not conform to all of the requirements in Table1.4.2.1 Hence, no single performance specification can possi-bly apply to all the various fabrics that could be utilized for thisend-use.4.3 The uses and significance of particular p
16、roperties andtest emthods are discussed in the appropriate sections of thespecified test methods.5. Test Methods5.1 Breaking Force (Woven Fabrics Only) Determine thedry breaking strength (load), as directed in the grab testprocedure of Test Methods D 5034 using a constant-rate-of-extension (CRE) ten
17、sile grab machine.NOTE 2If preferred, a constant-rate-of-traverse (CRT) tensile testingmachine may be used. There may be no overall correlation between theresults obtained with the CRT machine and with the CRE machine.Consequently, these two breaking load testers cannot be used interchange-ably. In
18、case of controversy, the CRE method shall prevail.5.2 Bursting Strength (knit fabrics only)Determine thebursting strength of knit fabrics in accordance with TestMethod D 3786 using an approved type of diaphragm burstingtester or as directed in D 3787 using an approved constant-rate-of-traverse (CRT)
19、 machine equipped with a burstingattachment.NOTE 3Care should be taken to subtract the tare diaphragm pressurefrom the gross pressure to obtain actual bursting strength of fabric whenusing the diaphragm bursting tester. Calibrate the equipment according tothe manufacturers instruction before using.
20、Since there is no overallcorrelation between the results obtained with the CRT machine equippedwith a bursting attachment and the diaphragm bursting tester, these twobursting testers cannot be used interchangeably. In case of controversy, theCRT machine equipped with a bursting attachment method sha
21、ll prevail.NOTE 4The precision of the ball burst method using the CRT machineequipped with a bursting attachment and the precision of the diaphragmbursting tester method are being established by Subcommittee D13.59.The methods are accordingly not recommended for acceptance testingunless preceded by
22、an interlaboratory check test in the laboratory of thepurchaser and the laboratory of the seller using randomized replicatespecimens of the material to be evaluated.5.3 Tearing Strength (woven fabrics only)Determine tearstrength as directed in Test Method D 2261.TABLE 1 Specification RequirementsNOT

Theremay be no overall correlation between the results obtained with the tonguetear machine and with the Elmendorf machine. Consequently, these twotester
29、s cannot be used interchangeably. However, in case of controversy,Method D 2261 shall prevail.5.4 Dimensional Change:5.4.1 LaunderingDetermine the dimensional change after5 launderings as directed in Test (I) (II A) of AATCCMethod 135 .NOTE 6Launderable fabrics are expected normally to be dry-cleana
