ASTM D3691-95a

Standard Performance Specification for Woven, Lace, and Knit Household Curtain and Drapery Fabrics

SCOPE
1.1 This performance specification covers the requirements for all knit, lace, foam back, stitch-bonded, conventional weights, and sheer woven fabrics to be used in the manufacture of curtains and draperies.  
1.2 This performance specification is not applicable to fabrics made of glass.  
1.3 For those properties where fabric direction is pertinent, these requirements apply to the length and width directions for woven fabric and to both the wale and course directions for knit fabric.
1.4  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

There is more than one standard test method that can be used to measure breaking strength, bursting strength, tear strength, and lightfastness. These test methods
cannot be used interchangeably since there may be no overall correlation between them (see Note 2, Note 3, Note 4, Note 5, and Note 9).
B
Class in colorfastness and DP rating is based on a numerical scale of 5.0 for negligible color change, color transfer, or wrinkling to 1.0 for very severe color change,
color transfer, or wrinkling. The numerical rating in Table 1 or higher is acceptable.
