- Scope
- This standard specifies the method for determining the fiber content in a two-component mixture of cross-linked lyocell fiber and viscose fiber, cupro fiber or modal fiber by using the formic acid/zinc oxide method after removing non-fiber substances. This standard applies to two-component mixtures of cross-linked lyocell fiber and viscose fiber, copper-nitrogen fiber or modal fiber. This standard does not apply to mixtures containing cross-linked lyocell fibers that have been severely chemically degraded, nor does it apply to mixtures containing certain viscose fibers, copper-nitrogen fibers or modal fibers that cannot be completely decomposed .
