1.1 This test method covers stiffness properties of nonwoven fabrics by employing the principle of cantilever bending of the fabric under its own weight. Bending length is measured and flexural rigidity calculated.

1.2 This test method applies to most nonwoven fabrics that are treated or untreated, including those heavily sized, coated, or resin-treated.

1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses may be approximate.
