This test method covers the determination of the amount of extractable matter in samples of all forms of wool, except grease wool, that is extractable with trichlorotrifluoroethane (CCl2-FCClF2).

Formerly under the jurisdiction of Committee D13 on Textiles, this test method was withdrawn in June 2004 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 This test method covers the determination of the amount of extractable matter in samples of all forms of wool, except grease wool, that is extractable with a non-flammable vapor degreasing and cleaning solvent.

1.2 This test method does not cover the determination of the amounts of different components in the extracted matter nor their identification.

1.3 This test method is suitable for use with other animal fibers. Note 1The determination of extractable matter in yarns and in felts is covered in Test Methods D 2257 and D 461. For the determination of alcohol-extractable matter in oven-dry scoured wool, refer to Test Methods D 584 and D 1334.

1.4 The values stated in SI units are to be regarded as the standard.

This standard does not purport to address 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. See and Note 3.
