Each AATCC standard is reviewed at least once every five years. Be sure to use and reference only the most current versions.


Letters indicate the type of standard: TM = test method, LP = laboratory procedure, EP =  Evaluation Procedure, M = monograph. Each AATCC standard is designated by a number followed by the year of last technical revision. The last subsequent reaffirmation may appear in parentheses. A small letter “e” indicates editorial changes and a small letter “t” indicates additional technical changes in the same year.
