1.1 This specification covers soft or annealed bare copper wire, rectangular or square in shape with rounded corners (Explanatory Note 1).
1.2 For the purpose of this specification, the wire is classified as follows:
1.2.1 Type A—For all applications except those involving edgewise bending.
1.2.2 Type B—For applications involving edgewise bending. Type B wire of thickness less than
0.020 in. (0.51 mm) or with a ratio of width to thickness greater than 30 to 1 is not contemplated in this specification.
1.3 Unless otherwise specified by the purchaser, Type A material shall be furnished.
1.4 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; except for Sections 12 and 13.
1.5 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.
