1.1 This test method covers a procedure for determining the extractable material on most fibers, yarns, and fabrics. Three options are included. Option 1 uses heat and Soxhlet extraction apparatus. 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.
Note 1—Other standards for the determination of extractable matter in textiles made of specific fibers include: Specification , Specification , and Test Method D1574.
1.1.1 The solvents for use in this method are any solvents that the party or parties concerned agreed on; such as, Halogenated Hydrocarbon (HH) chloroform, tetrachloroethane, alcohol.
1.1.2 This test method may not extract cross-linked finishes or resins which may be on the textile.
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. See Sections 6 and 7.
