ASTM D2612-99(2011)

1.1 This test method describes the measurement of fiber cohesion as the force required to cause initial drafting in a bundle of fibers in sliver and top. The observed cohesive force required to separate the fibers is converted to cohesive tenacity based on the linear density of the specimen.

Note 1 – For determination of fiber cohesion in dynamic tests, refer to Test Method D4120.

1.2 The values stated in SI units are to be regarded as standard. Inch-pound units appear in parentheses for information only.

1.3 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.
