AATCC 
The research committee RA111, Electronically-Integrated Textiles, of the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA, has approved its first evaluation procedure. AATCC EP13, Evaluation Procedure for Electrical Resistance of Electronically-Integrated Textiles, is one of the very first international standards for e-textiles.
The procedure provides detailed instructions for measuring resistance of e-textiles – a key indicator of functionality. It also includes guidance and calculations for determining change in resistance after laundering, stretch, or other treatment. The procedure can be performed on a variety of materials, including those with woven, knitted, printed, or stitched conductive elements. AATCC EP13 is suitable for component fabrics or complete e-textile products. It is designed to be performed in standard atmospheric conditions for textile testing and the apparatus can be purchased inexpensively from a variety of sources.
