New Chain Link Fence Standard Will Have Homeland Security Applications

ASTM Committee F14 on Fences has approved a new chain link fence standard that will have a variety of security applications. The standard, F 2611, Guide for Design and Construction of Chain Link Security Fencing, contains information on the proper material selection, system installation and layout, all of which can substantially increase the difficulty of penetration. F 2611 is under the jurisdiction of Subcommittee F14.50 on High Security Fences and Perimeter Barriers.

According to William Ullrich, principal at Link Consulting LLC and leader of the F 2611 task group, the new standard was developed at the request of Subcommittee E54.05 on Building and Infrastructure Protection, which is part of ASTM International Committee E54 on Homeland Security Applications. Several members of Committee F14 also participate in E54 standards development activities and F 2611 will be incorporated into a proposed standard E54.05 is currently developing, WK10275, Guide for Perimeter Protection for Homeland Security Applications.

“The purpose of F 2611 is to provide the design and security engineers all the proper ASTM chain link material and installation options so that they can design a security fence that will comply with their specific security requirements, especially to detect an intruder and have sufficient delay time to respond and apprehend,” says Ullrich. The standard will be particularly useful for site and security engineers at power plants, refineries, manufacturing facilities, government buildings, military sites, airports and other sensitive areas.

In addition to developing F 2611, Ullrich says that Subcommittee F14.50 is currently working on similar fence design and construction guides that utilize F14 standards for expanded metal (F 2548, Specification for Expanded Metal Fence Systems for Security Purposes) and welded wire (F 2453/F2453M, Specification for Welded Wire Mesh Fence Fabric (Metallic-Coated or Polymer Coated) for Meshes of 6 in.2 [3871 mm2] or Less, in Panels or Rolls, with Uniform Meshes), as well as a guide for ornamental picket fencing.

Ullrich also notes that a recent revision to another F14 standard F 1083, Specification for Pipe, Steel, Hot-Dipped Zinc-Coatedd, (Galvanized) Welded, for Fence Structures, is related to the new F 2611 and the other standards F14.50 is developing. The revision to F 1083 includes the addition of a new schedule 40 pipe design that has exceptional strength. High strength 83000 was introduced to the standard specifically for high security fences that have small security mesh and fences using wind screens or privacy slates subjected to wind load.

Now that F 2611 has been approved, Ullrich says the subcommittee would like users to respond with any feedback that would be useful in future revisions of the standard. Any interested fencing and security experts are encouraged to participate in the ongoing activities of Subcommittee F14.50.
