Standard Terminology Relating to
Barbed Tape
This standard is issued under the fixed designation F 1379; 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.
1. Scope

1.1 This terminology is intended for use by barbed tape
specifiers and end-users to give a general understanding of the
types, sizes, and configuration of barbed tape.
