AATCC works closely with other industry organizations to provide members with the most current information, user-friendly resources, and relevant services.

ASTM InternationalASTM International’s Committee D13 develops test methods and specifications for textile materials. In general, AATCC methods and procedures focus on colorfastness, wet testing, and chemical properties. ASTM tests evaluate physical properties of textiles.

AATCC and ASTM have produced several joint publications.

AATCC incorporates ASTM methods in most of its Test Method Training programs. You can also purchase the Textiles volumes (7.01 & 7.02) of the Annual Book of ASTM Standards from AATCC.

Colour Index Direct BlueThe Colour Index is jointly published by AATCC and the SDC Enterprises. First published in 1924, it is now a convenient electronic tool.  It is the definitive guide for essential colorants. The Colour Index describes the essential colorant of a dye or pigment by application class and chemical class. Assigning a generic name and number allows identification by a globally recognized system. Dye manufacturers are invited to register their products.

ISO logoLike AATCC, the International Organization for Standardization (ISO) publishes test methods and procedures for evaluating textile materials. In fact, many ISO colorfastness and water resistance tests are taken directly from AATCC test methods.

For more than 60 years, AATCC was the co-secretariat for ISO/TC38/SC1—Textiles—Tests for Coloured Textiles and Colourants and secretariat for ISO/TC38/SC2—Textiles—Cleansing, finishing and water resistance tests. In 2010, AATCC transitioned these secretariats to other countries to focus on its own test methods and activities.

AATCC and ASTM International (Committee D13) are co-administrators of the Technical Advisory Group (TAG) representing the US in all TC38—Textiles activities. Although each country gets a single vote on ISO ballots, individuals may submit comments and opinions to be used in determining a country’s official position. To become a TAG expert and be consulted on ISO ballots, contact Diana Wyman.

AATCC has exchange membership relationships with numerous organizations around the world. This means additional resources, benefits, and discounts for all members.
