AATCCnormen

AATCCnormen are the standardized test methods and evaluation procedures published by the American Association of Textile Chemists and Colorists (AATCC) to assess the properties and performance of textiles. They cover a wide range of topics, from colorfastness to laundering, rubbing, perspiration and light exposure, to physical properties such as tensile strength, abrasion resistance, softness, and dimensional stability, as well as chemical and finish analyses and color measurement. The standards are developed by expert committees and are revised periodically to reflect new materials and testing practices.

Each standard typically includes scope, referenced documents, apparatus, specimen preparation, test method or evaluation procedure, calculation and data interpretation, and acceptance criteria. They can be used for quality control, product development, certification, and regulatory compliance. Results are reported in consistent units and rating systems, enabling comparison across labs and products.

AATCC standards are widely adopted internationally and are often used in conjunction with ISO and other regulatory schemes. They are distributed by AATCC, with access typically through membership or purchase; the organization also offers education and technical resources. In practice, laboratories, manufacturers, retailers, and testing houses rely on AATCCnormen to ensure reproducibility of textile testing and to support trade and quality assurance.
