4.1 Upon mutual agreement between the purchaser and the seller, woven fabrics intended for this end use should meet all of the requirements listed in Table 1 of this specification.
TABLE 1 Specification RequirementsNote 1-The classes of colorfastness in the AATCC methods referenced in this table are based on a numerical scale of 5 for negligible or no color change or color transfer to 1 for very severe color change or color transfer.

A More than one method can be used to measure these properties. These methods cannot be used interchangeably since there can be no overall correlation between them (see Note 2, Note 3, and Note 7).B AATCC Gray Scale for Color Change.C AATCC Gray Scale for Staining.D AATCC 9-Step Chromatic Transference Scale.E It has been reported that the results for staining, obtained by standard AATCC Test Methods, on fabrics dyed to dark shades that contain a combination of polyester and spandex, or their blends, may not show the full staining propensity of such fabrics in consumer use. It is, therefore, recommended that the staining results obtained by these tests not be used for acceptance testing of such fabrics.
4.2 It is recognized that for purposes of fashion or aesthetics the ultimate consumer of articles made from these fabrics may find acceptable fabrics that do not conform to all of the requirements in Table 1. Therefore, one or more of the requirements listed in Table 1 may be modified by mutual agreement between the purchaser and the seller.
4.2.1 In such cases, any references to the specification shall specify that: This fabric meets ASTM Specification D3655 except for the following characteristic(s).
4.3 Where no prepurchase agreement has been reached between the purchaser and the seller, and in case of controversy, the requirements listed in Table 1 are intended to be used as a guide only. As noted in 4.2, ultimate consumer demands dictate varying performance parameters for any particular style of fabric.
4.4 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.
