    1. Scope

    1.1 This specification covers bare hard-drawn round copper-clad steel wire for electrical purposes (Note 1).

    Note 1—Wire ordered to this specification is not intended for redrawing. If wire is desired for this purpose, consult the manufacturer.

    1.2 Four grades of wire are specified, designated as follows (Note 2): Grade 40 HS, Grade 40 EHS, Grade 30 HS, and Grade 30 EHS.

    Note 2—The grades covered by this specification correspond to the following commercial designations:

    Grade 40 HS,High Strength, 40 % Conductivity.
    Grade 40 EHS, Extra High Strength, 40 % Conductivity
    Grade 30 HS, High Strength, 30 % Conductivity.
    Grade 30 EHS,
    Extra High Strength, 30 % Conductivity.
