19、Table 1.5. Significance and Use5.1 Upon mutual agreement between the purchaser and theseller, fabrics intended for this end use should meet all of therequirements listed in Table 1 of this specification.5.2 It is recognized that for purposes of fashion or aestheticsthe ultimate consumer of articles
20、made from these fabrics mayfind acceptable fabrics that do not conform to all of therequirements in Table 1. Therefore, one or more of therequirements listed in Table 1 may be modifed by mutualagreement between the purchaser and the seller.5.2.1 In such cases, any references to the specification sha
21、llspecify that: “This fabric meets ASTM Specification D 3995except for the following characteristic(s).”5.3 Where no prepurchase agreement has been reachedbetween the purchaser and the seller, and in case of contro-versy, the requirements listed in Table 1 are intended to be usedas a guide only. As
22、noted in 5.2, ultimate consumer demandsdictate varying performance parameters for any particular styleof fabric.5.4 The significance and use of particular properties and testmethods are discussed in the appropriate sections of thespecified test methods.6. Sampling6.1 Tests shall be performed on the

Test Methods (Note 1)7.1 Bursting StrengthDetermine the bursting strength asdirected in Test Methods D 3787 or D 3786.NOTE 3There is no overall correlation between the results obtainedwith
32、the CRT machine equipped with a bursting attachment and thediaphragm bursting tester. Consequently, these two bursting testers cannotbe used interchangeably. In case of controversy, Method D 3787 shallprevail.NOTE 4The precision of the ball burst method using the CRT machineequipped with a bursting
33、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 an interlaboratory check test in the laboratory of thepurchaser and the laboratory of the seller using

38、e the maximum dimensionalchange after three drycleanings as directed in 10.1.3.1 through10.1.3.5 of Test Methods D 2724 (see Notes 5 and 6 ).NOTE 5Launderable fabrics are expected to be drycleanable exceptwhere all or part of the fabric is not drycleanable and is so labeled. Forexample, the fabric c
39、ould contain a functional finish soluble in the solvent,or the fiber could be degraded by the solvent, which would be the casewith poly(vinyl) chloride fiber. “Drycleanable” goods are to be drycleanedonly.NOTE 6Specimens prepared for 7.2.1 may be used for 7.2.2, 7.2.3,and 7.2.4 as desired. When this
40、 is done, the dimensional change due tolaundering or drycleaning is calculated using Eq 1, due to laundering. Thedimensional change to pressing and finishing will have occurred in thefabric before it reaches the user. Therefore, it should not be included as apart of the dimensional change to launder
