1.1 This practice for sampling covers a procedure for obtaining samples from lots of grease, pulled, or scoured wool or related animal fibers in bales or bags for the determination of the clean wool fiber present by a procedure similar to that described in Test Method D 584.

1.2 The practice provides a description of suitable core sampling equipment, the sampling procedure, and the method for determining the number of packages to be bored and the number of cores to be taken from each sampled package.

1.3 Reliable estimates are given for the standard deviation of the percentage clean wool fiber present between packages and within packages for lots of many types of raw wool.

1.4 The values stated in inch-pound units are to be regarded as the standard. The SI units are in parentheses. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this practice.

1.5 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.
