Standard Performance Specification for Brassiere, Slip, Lingerie and Underwear Fabrics
ABSTRACT
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.
SCOPE
1.1 This performance specification covers fabrics used in brassieres underwear, slips, and lingerie.
1.2 These requirements apply to the length and width directions for those properties where each fabric direction is pertinent.
1.3 The following safety hazards caveat pertains only to the test methods described in this performance specification: 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.
