The American Society for Testing and Materials (ASTM) has published two standards concerning textile terminology and textile fiber testing.
ASTM D3136 - 14 Standard Terminology Relating to Care Labeling for Apparel, Textile, Home Furnishing, and Leather Products provides a uniform language for the disclosure of care instructions on labels that are to be attached to apparel, textile, home furnishing, and leather products according to the Federal Trade Commission’s regulation 16 CFR, Part 423. These terms, definitions and descriptions employ common meanings for the care instructions required to be on textile products sold in the U.S. and is unique to the care of textile and leather products as the meanings are often expressed in phrases for care processes related to home-type washers, dryers, drying techniques and those for professional care.
ASTM D3822 / D3822M - 14 Standard Test Method for Tensile Properties of Single Textile Fibers covers the measurement of tensile properties of natural and man-made single textile fibers of sufficient length to permit mounting test specimens in a tensile testing machine. This test method provides directions for measuring the breaking force and elongation at break of single textile fibers and for calculating breaking tenacity, initial modulus, chord modulus, tangent modulus, tensile stress at specified elongation, and breaking toughness.
