DURHAM, N.C.— January 21, 2026 — The 2026 Volume 101 marks a new Era following the Century Edition of the AATCC Manual of International Test Methods and Procedures and will be available starting January 1, 2026. Containing three new standards and twenty-eight revised standards, the latest Manual provides industry professionals with the most up-to-date textile testing procedures and methods available.
To enable textile industry personnel to stay on pace with the newest technologies and achieve excellence in testing and quality control, AATCC makes accessing the 2026 Manual quick and convenient through multiple purchase formats. Interested buyers can acquire the new edition Manual in hardback binding or as a downloadable PDF.
Individual test method standards can also be purchased. All items are available via the AATCC Online Store as a PDF.
To support IT security protocols that discourage the use of USB devices as potential intrusion points or risks to company’s networks, AATCC has discontinued the USB version of the Manual and instead offers a PDF download of the Manual. AATCC recommends companies and testing laboratories switch to the 2026 Manual when it is released as either a hardback or PDF to stay aligned with the most current methods available.
