1.1 This specification covers 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. PVC and other organic polymer coatings hereinafter will be designated as polymer coating.
1.2 Barbed wire strand wire, produced from three classes of wire coatings, is covered as follows:
1.2.1 Class 1, consisting of a polymer coating extruded over zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire;
1.2.2 Class 2a, consisting of a polymer coating extruded and adhered to zinc-coated or aluminum-coated or zinc-5 % aluminum-mischmetal alloy-coated steel wire; and
1.2.3 Class 2b, consisting of a polymer coating fused and adhered to zinc-coated or 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 for information only.
