Full Description

1.1 This test method covers the determination of the breaking tenacity of wool fibers as a flat bundle with a 1/8-in. (3.2-mm) clamp separation.

1.2 This test method is especially adapted to the fiber bundle clamps and strength testing instruments specified, but may be used on other tensile testing machines when equipped with appropriate adapters to accommodate the prescribed clamps.

1.3 This test method is applicable to wool in any form which can be hand-combed into small bundles of parallelized fibers.

Note 1 - Other test methods for measuring breaking tenacity of fiber bundles include Test Methods D 1294, D 1445, and D 540.

1.4 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.

1.5 The values stated in inch-pound units are to be regarded as the standard. The SI units in parentheses are provided for information only.
