This specification covers poly(vinyl chloride)(PVC) and other conforming organic polymer-coated steel barbed wire consisting of two polymer-coated strands, with four-point barbs of zinc-coated steel or aluminum alloy wire used with chain-link fence. PVC and other organic polymer coatings hereinafter will be designated as polymer coating. Barbed wire strand wire, produced from three classes of wire coatings, is covered as follows: class 1 - polymer coating extruded over zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; class 2a - polymer coating extruded and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; and class 2b - polymer coating fused and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire. Polymer-coated steel barbed wire is supplied in a choice of two types as follows: type I - standard, and type II - high security. Breaking strength of the stranded barbed wire shall be tested to meet the requirements prescribed. Adhesion test, accelerated aging test, and color test shall be made to meet the requirements prescribed.
