1.1 These test methods cover procedures for the determination of the fiber blend composition of mixtures of the fibers listed in 1.2. Procedures for quantitative estimation of the amount of moisture and certain nonfibrous materials in textiles are also described, for use in the analysis of mixtures, but these are not the primary methods for the determination of moisture content for commercial weights.
1.2 These test methods cover procedures for the following fiber types:
1.2.1 Natural Fibers:
1.2.1.1 Cellulose-Base Fibers: Cotton Hemp Flax Ramie
1.2.1.2 Protein-Base Fibers: Animal hairs (other than wool) Silk, cultivated Silk, Tussah Wool
1.2.2 Man-Made Fibers:
1.2.2.1 Cellulose-Base Fibers: Acetate (secondary) Rayon, viscose or cuprammonium Triacetate
1.2.2.2 Synthetic-Base Fibers: Acrylic Aramid Modacrylic Nylon 6, Nylon 6-6, others Olefin Polyester Spandex

1.4 The analytical procedures described in the test methods are applicable to the fibers listed in 1.2. The test methods are not satisfactory for the separation of mixtures containing fibers that fall within the same generic class but differ somewhat, either physically or chemically, from each other. These test methods are not satisfactory for the determination of bicomponent fibers.
Note 1-For other methods of analysis covering specific determinations, refer to: Test Methods D461, Test Method D584, Methods D885, Test Method D1113, Test Method D1334, and Test Method D2130. Methods for moisture are covered in Methods D885, Test Method D1576, Test Method D2462, Test Method D2495 and Test Methods D2654. For the determination of commercial weight, refer to Test Method D2494.
