Title
Standard Test Method for Extractable Matter in Textiles
ASTM International
Publication Date:
Sep 10, 1998
Scope:
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 D 541, Specification D 681, and Test
Method D 1574.
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.
This test method may not extract cross-linked finishes or resins which
may be on the textile.
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.
