American Association of Textile Chemists and Colorists (AATCC) research committee has released the 2020 mid-year supplement in the AATCC Technical Manual which includes nine revised test methods, one editorially revised test method, and one revised monograph for a total of eleven approved standards. AATCC based in US, is the leading not-for-profit association, serving textile professionals since 1921.

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.

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.

In accordance with AATCC M13, Rules of Procedure for AATCC Test Method and Technology Committees, all technical changes are unanimously approved by the responsible research committee and the Technical Committee on Research (TCR) before publication, according to a press release by AATCC.
