AATCC Standard (American Association of Textile Chemists and Colorists)

The AATCC standard is a textile testing method standard established by the American Association of Textile Chemists and Colorists, widely used for testing colorfastness, physical properties, biological properties, etc. In foreign trade, AATCC standards are often used in order contracts, quality inspection reports, and product specifications as a basis for measuring whether product quality meets requirements. Usage scenarios include: textiles exported to the United States must comply with AATCC standards; buyers require AATCC test reports; quality control during production is based on AATCC standards. Notes: AATCC standards differ from ISO standards, GB standards, etc., and test methods and ratings may vary; the specific standard numbers and test items required by the customer must be clarified; some AATCC standards are updated annually, and the latest version should be used. Differences from ISO standards: AATCC standards focus more on the U.S. market, and test conditions (such as temperature, humidity, washing procedures) may be stricter or different; compared with GB standards, AATCC standards are more commonly used in international trade, especially for exports to the U.S. Foreign trade practitioners should be familiar with common AATCC test items, such as colorfastness (AATCC 16, AATCC 61), pilling resistance (AATCC 124), etc., and specify the standard version and test method in the contract.
