Related Organizations


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

ASTM International

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

AATCC and ASTM have published several joint Testing Supplements. These supplements are compilations of procedures and guidelines for textile products, not yet included in the official AATCC Technical Manual or Annual Book of ASTM Standards. Some are based on long standing industry practices or protocols developed by specific companies for in-house use.

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

The Colour Index is jointly published by AATCC and the Society of Dyers and Colourists (SDC). 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 for free.


Like AATCC, the International Organization for Standardization (ISO) publishes test methods 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 secretary for ISO/TC38/SC2—Textiles—Cleansing, finishing and water resistance tests. In 2010, AATCC transitioned these secretariats to other countries in order to focus on its own test methods and 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.

AATCC and ASTM International-Committee D13 Textiles are co-administrators of the Technical Advisory Group (TAG) representing the US in all TC38—Textile activities. To become a TAG expert and be consulted on ISO ballots, contact Diana Wyman.
