1、Designation: F2611 11Standard Guide forDesign and Construction of Chain Link Security Fencing1This standard is issued under the fixed designation F2611; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A n

2、umber in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide provides the material and installation stan-dards for selection in the design of a security chain link fencesystem. The prope

3、r material selection, system installation andlayout can substantially increase the difficulty to penetrate;thereby, increasing the intrusion delay time.1.2 This guide does not purport to address all of the physicalprotection security concerns. It is the responsibility of the userof this standard to

4、establish the appropriate design for the levelof physical protection required and determine the applicabilityof regulatory requirements or limitations prior to use.1.3 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to

5、SI units that are provided for information onlyand are not considered standard.1.4 It is recommended that Guide F1553 be followed for theformat of this guide.2.
