1、Designation: F 1379 95 (Reapproved 2003)Standard Terminology Relating toBarbed Tape1This standard is issued under the fixed designation F 1379; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in

2、parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This terminology is intended for use by barbed tapespecifiers and end-users to give a general understanding of thetypes, sizes, and configuratio

3、n of barbed tape.2. Terminologyattachment points, npoints where alternate pairs of coilloops are joined around the circumference creating theconcertina effect. (1992)barb length, nmeasured from the barb point to the centerline of the barb cluster. (1992)barb length classification, ncommonly used bar

4、bed typesdescribing length and shape; such as long barb, mediumbarb, and short barb. (1995)barb spacing, nthe circumferential or linear distance be-tween the center lines of the barb clusters. (1992)barbed tape, nstrip of metal, machined to produce clustersof sharp points. (1992)clip, na mechanical

5、means of joining two loops. (1992)coil loop, none complete rotation (360) of barbed tape.(1995)coil rotation, nthe spiraling effect that occurs as the concer-tina coils are deployed. (1993)concertina, na pattern formed by attaching adjacent loops ofhelical coils to one another at specified points on

6、 thecircumference, resulting in an accordion-like configuration.(1992)concertina spacing, ndistance between adjacent concertinaattachments in a concertina configuration, as measured downthe length of the extended coil (also called concertinaattachment spacing). (1992)cross section, nshows the width

7、and thickness of material,including the center sections shape, core diameter, and corewrap. (See Figs. 1-3 for types.) (1993)deployed length, nthe coils as extended for use. It isspecified by the coverage where:Helical coverage = number of coil loops per unit 3 helical loopspacingConcertina coverage

8、 = number of coil loops divided by 2 3 concer-tina loop spacing. (1992)diameter, nspecified size diameters shall be measured acrossthe center line of the packaged coil with a tolerance of 62in.; installed diameters are always less than the packageddiameter of the coil. (1992)double coil, na configur

9、ation where a smaller diameter coilis placed inside a larger diameter coil. The assembled rollsmay be either concertina style or helical style. (1993).DISCUSSION 1. Concertina style, for example, the 24 and 30-in. 61and 76-mm diameter coils are attached together at both ends forinstallation purposes

10、.DISCUSSION 2. Helical style, for example, the 24 and 30-in. 61 and76-mm diameter coils are alternately attached together throughout theroll in four places around the circumference. In addition, one coil isfabricated in reverse helix to the companion coil.double loop ties, ntwistable ties used to se

11、cure the barbedtape at the tie point (also known as bag ties). (1993)flange, nthe extension of the wrap beyond the core wire orstiffening groove. See Fig. 4. (1993)helical, nthe most simple pattern in a barbed tape coil wherethere are no concertina attachments and each coil loop is leftfree in its n

14、a helical coil configuration. (1992)long barb, nbarbs having an average length of 1.2 6 5%.(1995)loop spacer wire, nwire that is attached loop-to-loop (or onconsecutive attachment points) on the barbed tape to presetthe loop spacing. (1992)medium barb, nbarbs having an average length of 0.4 65 %. (1

15、995)off set barbs, nangling of the barb cluster from the centerline of the tape in opposite directions. See Fig. 5. (1993)short barb, nbarbs having an average length of 0.1875 65 %. (1995)single coil, na configuration where there is one coil with onediameter, the coil being either helical or concert

(1993)splicing tail, nthe barb clusters extending beyond the lastattachment at both ends of the coil. (1993)ti
