Standard Terminology Relating to
Sewn Products Automation
This standard is issued under the fixed designation D 6963; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
