Scope

1.1 This specification covers round, extra-high-strength and ultra-high-strength, Class A zinc-coated (galvanized), steel core wire used for use in Overhead Electrical Conductors.

1.2 This specification covers wire of diameter from 0.0500 to 0.1900 in. inclusive or 1.27 to 4.82 mm inclusive.

1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard.
