As the voice of the U. Option 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue. Option 1 uses heat and Soxhlet extraction apparatus.

Subscription pricing is determined by: Option 2 uses room temperature and extraction funnels.

Option 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue. As a minimum, the two parties should take a group of test specimens which are as homogeneous as possible and which are from a lot of material of the type in question.

The test method may be used as a step in the determination of the commercial weight of fiber, yarn, and textile shipments. This test method atsm used astk the determination of the amounts of naturally present oily or waxy impurities that have not been completely removed from textiles made from animal fibers, and for the determination of the amounts of oily or waxy finishing materials applied to raw materials or textiles during manufacture.
