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 publication of the 2020 AATCC Technical Manual.
These documents are available ONLY as downloadable PDFs for 2020. The 2020 Mid-Year Supplement will be discontinued at the end of 2020 and all standards contained therein will appear in the 2021 AATCC Technical Manual.
