Standard Test Method for Wool Content of Raw Wool - Commercial Scale
1.1 This test method covers the determination of the wool base content and the clean wool fiber present in a lot of raw wool by commercial-scale scouring of the lot followed by laboratory tests on samples of the scoured wool.
Note 1: The sampling of lots of raw wool in packages is covered in Practice D1060, and the determination of the wool content of such samples is covered in Test Method D584. The determination of vegetable matter and other alkali-insoluble impurities in scoured wool is covered in Test Method D1113. For factors for the conversion of wool base content to its equivalent in terms of scoured wool, top, or noil of various commercially specified compositions, refer to Practice D2720.
Note 2: The values stated in U.S. Customary Units are to be regarded as the standard because of common commercial practice. The S.I. units in parentheses are provided for information only.
Note 3: Because of trade practice the term “weight” is used in this test method instead of the technically correct term “mass”.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
