aatccThe American Association for Textile Chemists and Colors (AATCC) Research Committee has published new guidelines and research procedures. Data are released two times a year: in January in the AATCC Technical Manual and in June in the mid-year Supplement. A total of 11 accepted criteria of 9 updated test methods, 1 editorially updated test method and 1 revised monograph are included in the latest supplement.

AATCC research committees work year-round to develop and update standards. The results are published twice per year—in the AATCC Technical Manual each January and in the Mid-Year Supplement each June. The 2020 Mid-Year Supplement is now available and includes nine revised test methods, one editorially revised test method, and one revised monograph for a total of eleven approved standards since the publication of the 2020 AATCC Technical Manual.
