ASTM F2548-12

Standard Specification for Expanded Metal Fence Systems for Security Purposes

ABSTRACT
This specification covers the selection and installation of expanded metal fence systems for applications on new or retrofit fences capable of denying or delaying unwanted access into or out of a commercial, industrial, governmental, or institutional facility as applicable to homeland security, or where the possibility of malevolent incursion is significant. The metal fences can be expanded (Type 1), or expanded and flattened (Type 2); and uncoated (Class 1), hot-dip zinc coated or galvanized (Class 2), or corrosion-resisting steel (Class 3). Fencings shall conform to specified standard sizes and dimensions.
SCOPE
1.1 This specification covers selection and installation of expanded metal fence systems for applications on new or retrofit fences for commercial, industrial, governmental or institutional facilities as applicable to homeland security, or where the possibility of malevolent incursion is significant. See Fig. 1 for typical examples of expanded metal fence applications. This type of fence system is not recommended for residential or public recreational facilities such as pools, schools, and kindergartens.
FIG. 1 Expanded Metal Fencing Applications  
1.2 This specification is intended to guide those responsible for or concerned with the design and installation of an expanded metal fence system capable of denying or delaying unwanted access into or out of an area.  
1.3 No recommendation is made or implied here as to the merits of the product from any particular manufacturer. Choice of component selection for the expanded metal system should be made by the writer of the project specification based on their own perception of the product’s merit and the consequence of a malevolent incursion.  
1.4 The values stated in inch-pound units are to be regarded as standard. Any values given in parentheses are for information only.  
1.5 This specification does not purport to address all of the safety and security concerns, if any, associated with homeland security. It is the responsibility of the user of this standard to establish the required and appropriate level of security.
