The 2023 edition of the Manual of International Test Methods and Procedures has been released by the AATCC. This is the 98th volume of the AATCC Manual and will be available for purchase from January 2023. It is available as a hardbound book, USB, and individual standard PDFs.
There are 15 new or technically revised standards in the 2023 Manual from the American Association of Textile Chemists and Colorists (AATCC), Research Triangle Park, NC/USA. Several methods have been reorganized for easier use. Most notably, AATCC TM197 was separated into 2 methods for vertical wicking.
TM197 is now specifically for evaluating wicking rate to specified distances. AATCC TM213 is a new method for evaluating wicking rate to specified times. Both methods provide guidance and troubleshooting for everything from timing multiple specimens to optimal viewing for dark specimens.
