ASTM D3996-95

Standard Performance Specification for Knit Swimwear Fabrics

SCOPE
1.1 This performance specification covers circular and warp knitted fabrics for use in knit swimwear, composed of any textile fiber or mixture of textile fibers.
1.2 These requirements apply to both the length and width directions for those properties where fabric direction is pertinent.
1.3 The following precautionary statement pertains only to the test methods portion, Section 7, of this 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.
