ASTM F668-17

Standard Specification for Polyvinyl Chloride (PVC), Polyolefin and Other Polymer-Coated Steel Chain Link Fence Fabric

ABSTRACT
This specification covers polyvinyl chloride and other conforming organic polymer-coated steel chain-link fabric, coated before weaving. Fabric produced from three classes of wire coatings are covered as follows: Class I consists of polymer coatings extruded over zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire; Class 2a consists of polymer coating extruded and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire; Class 2b consists of polymer coating fused and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire. Materials shall be tested and the individual grades shall conform to material, weave, mesh size, diamond count, wire size, fabric height, selvage, breaking strength, weight of Zinc, Aluminum, or Zinc-5 % Aluminum-Mischmetal Alloy Coatings, polymer coating thickness, polymer-coated wire, and roll length.
SCOPE
1.1 This specification covers polyvinyl chloride and other conforming organic polymer-coated steel chain-link fabric, coated before weaving. Polyvinyl chloride, polyolefin, and other organic polymer coating hereinafter will be designated as polymer coating.  
1.2 Fabric produced from three classes of wire coatings are covered as follows:  
1.2.1 Class I consists of polymer coatings extruded over zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire.  
1.2.2 Class 2a consists of polymer coating extruded and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire.  
1.2.3 Class 2b consists of polymer coating fused and adhered to zinc-coated, aluminum-coated, or zinc-5 % aluminum-mischmetal alloy-coated steel wire.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
