1、Designation: F 1911 05Standard Practice forInstallation of Barbed Tape1This standard is issued under the fixed designation F 1911; 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 parentheses i

2、ndicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice covers the installation procedure forbarbed tape.1.2 The primary purpose of this practice is to guide thoseresponsible for, or concerned with,

3、the installation of barbedtape on chain link fences, masonry walls, roofs or used asground barriers. This practice is not intended to cover aspectsof perimeter security for establishing levels of product perfor-mance or give analysis relating to various design comparisons.1.3 This practice involves

4、the use of material, that maycause injury, including exposure to hazardous materials, andoperation of specialized equipment.1.4 This standard does not purport to address all of thesafety concerns, if any associated with its use. It is theresponsibility of the user of this standard to establish appro

10、 recom-mended for top of the fence installations. Single 45 barb armswith a single strand of barbed wire or tension wire located inthe outer position of the arm will support coils deployed at thetop of the fence. Barb arms are positioned so that arms are outof reach from the approach side. “V” arms

11、are not recom-mended for security applications where climbing is a threat orwhere only one row of barbed tape is specified. Two rows ofbarbed tape are recommended where “V” arms are specified.See Fig. 1.6.2.2.1 DeploymentStretch the coils out and allow themto rotate (spiral) naturally around their c

12、entral axis. Allowingthe coil to rotate will ensure that there is no mechanical stresswithin the obstacle before tying. Locate the coil loops uni-formly at the specified coil spacing. The coil spacing ispredetermined by one or more permanently attached cablesrunning the entire length of the roll. Th

13、e number of cablesdepends largely on the diameter and application. Coil loopspacing for non-reinforced products are generally 12.0 inches.See Fig. 2.6.2.2.2 Tie PointsBefore making the final attachment tothe fence, inspect the coils for tangles and proper coil spacing.Attach the first ties to the si

Improper coil loop spacing and tang

Every coil intersecting the fence need not be tied. Tiesfor detention applications are stainless steel 16 gage minimum;for commercial and industri

22、the Fence InstallationGround barriers arecoils placed horizontal, in vertical stacks at the base of thefence and tied consecutively together. Stacked coils are tiedapproximately 36 in. to 48 in. on center (o.c.) to adjacent rows.See Fig. 3.6.2.4.1 DeploymentFollow deployment instructions de-scribed

Connect the tworolls at the point where the cable (or cables) from each rollcome together. Tie the cable loops and closest barb

24、 clustertogether with the minimum 18 gage stainless steel tie wire.This tie secures the ends of the cables and matching barbclusters together. Maintain a uniform diameter by aligning theremaining barb clusters around the perimeter of the coil.Complete the splice by tying the end turns of the leading

25、 andtrailing rolls together. Place additional ties where the coilswould have been spot welded if manufactured into onecontinuous roll. Additional ties may be required to strengthenor improve on the appearance of the splice.NOTE 2It is important that larger diameter coils with two or morecables have

26、at least one cable continue uninterrupted through the entirerun. This prevents diameter distortion at the splice.6.2.6 Ground AnchorsCoils deployed on the ground shallbe anchored as required, depending on the application andsecurity threat.
