The AATCC research committee RA111, Electronically-Integrated Textiles, recently approved the evaluation procedure, AATCC EP13, Evaluation Procedure for Electrical Resistance of Electronically-Integrated Textiles. 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. AATCC standards are developed, approved and periodically reviewed by a global team of volunteer subject matter experts. The standards are recognized and used around the world.
