    Significance and Use

    4.1 Fabrics intended for this end-use should meet all of the requirements listed in Table 1.

    (A) 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 SA 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.
    (C) AATCC Gray Scale for Color Change.
    (D) AATCC Gray Scale for Staining.
    (E) AATCC 9-Step Chromatic Transference Scale.
    (F) For durable-press fabrics only.
    (G) The development of a standard method has been referred to the American Association of Textile Chemists and Colorists.

    4.2 It should be recognized that fabric can be produced utilizing an almost infinite number of construction variables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finished). Additionally, fashion and aesthetics dictate that the ultimate consumer may find acceptable articles made from fabrics that do not conform to all of the requirements in Table 1.

    4.2.1 Hence, no single performance specification can possibly apply to all the various fabrics that could be utilized for this end-use.

    4.3 The uses and significance of particular properties and test methods are discussed in the appropriate sections of the specified test methods.

    1. 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 applicable to all fabrics except those 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 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

    1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
