1.1 This test method covers a laboratory procedure for the determination of the wool base content and the clean wool fiber present in samples of raw wool. This test method is also applicable to other animal fibers such as mohair, cashmere, alpaca, and camel hair.

Note 1 - Sampling of lots of raw wool in packages is covered in Practice D1060; the determination of vegetable matter and other alkali-insoluble impurities in scoured wool is covered in Test Method D1113; the determination of wool content on a commercial scale is covered in Test Method D1334. For factors for the conversion of woolbase content to its equivalent in terms of scoured wool, top, or noil of various commercially specified compositions (formerly covered in the appendix of this test method), refer to Practice D2720.

Note 2 - Because of the trade practice the term weight is used in this test method instead of the technically correct term mass.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.
