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

4.2 It should be recognized that fabric can be produced utilizing an almost infinite number of combinations of construction variables (e.g., type of fibers, percentage of fibers, yarn twist, yarn number, warp and pick count, chemical and mechanical finishes). Additionally, fashion or 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.

This performance specification covers fabrics used in brassieres underwear, slips, and lingerie. The requirements apply to the length and width directions for those properties where each fabric direction is pertinent. The fabric shall conform to the required breaking strength, tearing strength, resistance to yarn slippage, bursting strength, dimensional change, colorfastness, appearance, and flammability.
