Scope

1.1 This test method covers the determination of the breaking force (or load) and estimation of the tensile strength and tenacity of wool fiber bundles with a 1-in. (25.4-mm) gage length. A procedure for preparation of the fiber bundle is included.

1.2 The values stated in inch-pound units are to be regarded as standard; the values in SI units are provided for information only. Because the instrument is calibrated in inch-pound units, inch-pound units are shown first, contrary to Committee D13 policy.

Note 1--For other methods of measuring breaking tenacity of fiber bundles, refer to Test Methods D1445 and D2524.

Note 2--This test method can be used for other fibers that lend themselves to the same kind of preparation but the difference in density must be taken into account when calculating the tensile strength. It is not necessary to know or correct for the density of a fiber when calculating breaking tenacity.

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.
