    1. Scope

    1.1 This test method covers the determination of the content of oven-dried, ash-free, alcohol extractive-free vegetable matter and other alkali-insoluble impurities present in scoured wool. It is also applicable to related fibers such as the hair from the goat, camel, alpaca, and other animals.

    Note 1—The determination of clean wool fiber present on a laboratory scale is covered in Test Method D 584, the determination of clean wool fiber present on a commercial scale is covered in Test Method D 1334, and the calculation of commercial weight and yield of various commercial compositions (formerly covered in Appendix to Test Method D 584) is covered in Practice D 2720.

    1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use.
