Source: ASTM International

This specification covers gabions and revet mattresses produced from double-twisted metallic-coated wire mesh, and metallic-coated wire for lacing wire, stiffeners, and fasteners used for manufacturing, assembling, and installation of the product. Double-twisted wire gabions and revet mattresses are classified according to coating, as follows: Style 1, Style 2, Style 3, Style 4. The wire used in the manufacture of double-twisted mesh for use in gabions and revet mattresses shall conform to the specific styles. Lacing wire and stiffeners shall be made of wire having the same coating material as the double-twisted wire mesh. The mechanical properties such as tensile strength shall be meet for the different styles of wires. Coatings shall conform to the required specific gravity, tensile strength, modulus of elasticity, hardness, and brittleness temperature, resistance to abrasion, salt spray exposure and ultraviolet exposure.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers gabions and revet matresses produced from double-twisted metallic-coated wire mesh, and metallic-coated wire for lacing wire, stiffeners, and fasteners used for manufacturing, assembling, and installation of the product. This specification also covers gabions and revet mattresses in which the wire mesh, lacing wire, and stiffeners are poly(vinyl chloride) (PVC) coated after the metallic coating.

1.2 Double-twisted wire mesh for gabions and revet mattresses is produced in different styles, based on type of coating, as described in Section 4.

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

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, Section 13, 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.
