AATCC M11-2018, A Glossary of AATCC Standard Terminology, collects the definitions of terms used across AATCC test methods and evaluation procedures so that wording is applied consistently from one document to another. Entries cover fiber, yarn, fabric, coloration, finishing and testing vocabulary, including the terms that carry a specific meaning inside AATCC methods. Laboratories, technical writers and quality staff use the glossary alongside the individual test methods.
