AATCC Test Methods and Evaluation Procedures

AATCC is probably best known for its standardized test methods and evaluation procedures, compiled in the annual AATCC Technical Manual. Each test method is designated by a number followed by a date, which indicates the year in which the method was issued, last revised, or reaffirmed. The designation should be quoted in full in referring to a particular method.

An important feature of all AATCC test methods is that test results are numerically quantified as opposed to being reported as pass-fail. Test results are the basis for describing material or process characteristics that are not in themselves intended to be performance specifications. AATCC policy prohibits endorsement of such specifications. Buyer and seller, or regulatory bodies, may establish pass-fail specifications based on the results of AATCC test methods. AATCC does not define "passing" or "failing" results for any test.
