ASTM B227-15(2019) PDF

Scope: 1.1 This specification covers bare hard-drawn round copperclad 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. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
