Test Methods (See Note 1)7.1 Bursting StrengthDetermine bursting strength of knit fabrics as directed in Test Method D3786 (preferred method) or TestMethod D3787NOTE 3The precision of the bursting strength testers has not been established and the results are not interchangeable. The met

30、hods are accordinglynot recommended for acceptance testing unless preceded by an interlaboratory check in the laboratories of the purchaser and the supplier, usingrandomized replicate specimens of the material to be evaluated.7.2 Colorfastness to LaunderingDetermine the colorfastness to laundering a

31、s directed in AATCC Test Method 61 or asotherwise agreed upon between purchaser and the supplier.NOTE 4It has been reported that the results for staining, obtained by standard AATCC Test Methods, on fabrics dyed to dark shades that contain acombination of polyester and spandex, or their blends, may

32、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.7.3 Colorfastness to DrycleaningFor drycleanable fabrics, determine the colorfastness to laundering

33、 as directed in AATCCTest Method 132 or as otherwise agreed upon between purchaser and the supplier.7.4 Colorfastness to CrockingDetermine the colorfastness to crocking as directed in AATCC Test Method 8 for shades andAATCC Test Method 116 for prints or as otherwise agreed upon between purchaser and

34、 the supplier.supplier (see Note 4).7.5 Colorfastness to LightDetermine the colorfastness to light as directed in AATCC Test Method 16, Option 3.NOTE 5There are distinct differences in spectral distribution between the various types of machines listed inAATCC Test Method 16, with no overallcorrelati

35、ons between them. Consequently, these machines cannot be used interchangeably.
