ASTM F2919/F2919M-12

Standard Specification for Welded Wire Mesh Fence Fabric (Metallic-Coated or Polymer Coated) with Variable Mesh Patterns or Meshes Greater than 6 in.² [3871 mm²] in Panels

ABSTRACT
This specification covers welded wire mesh fence fabric produced from steel wire or metallic-coated steel wire. The metallic-coated fabric may be polymer coated after fabrication. This specification identifies the three major classifications of welded wire mesh fence fabric - Panel Sizes Model A, B, and C - and the test methods conducted on the welded wire fabric. It also indicates the physical properties, dimension, tolerance, and workmanship of the welded wire mesh fence fabric.
SCOPE
1.1 This specification covers welded wire mesh fence fabric produced from steel wire or metallic-coated steel wire. The metallic-coated fabric may be polymer coated after fabrication.
1.2 Welded wire mesh fence fabric is produced in four types, based on the kind of coating, as described in Section 4.
1.3 This specification is applicable to orders in either inch-pound units or SI units. Values stated in either inch-pound or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values in the two systems are not exact equivalents; therefore, each system shall be used independent of the other, without combining values in any way.
1.4 This specification references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this specification.
1.5 The following safety hazards caveat pertains only to the test methods portion, 13.4, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
