Abstract:

This specification covers gabions and gabion mattresses produced from metallic-coated welded wire fabric, and metallic-coated wire for spiral binders, lacing wire, and stiffeners used to assemble the product. The material shall conform to the required values of tensile strength, weld shear strength, panel-to-panel joint strength. Salt spray and ultraviolet exposure tests shall be performed wherein the PVC coating shall conform to the required values of specific gravity, tensile strength, elastic modulus, hardness, brittleness temperature and resistance to abrasion.

Scope:

1.1 This specification covers gabions and gabion mattresses produced from metallic-coated welded wire fabric, and metallic-coated wire for spiral binders, lacing wire, and stiffeners used to assemble the product. The metallic-coated fabric may be polyvinyl chloride (PVC) coated after fabrication. The spiral binders, lacing wire, and stiffeners may be PVC coated after metallic coating. olyvinyl chloride hereinafter will be designated as PVC.

1.2 Welded wire fabric for gabions and gabion mattresses is produced in five styles, based on the kind of coating, as described in Section 4.

1.3 The values stated ihn inch-pound 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.
