Anotace textu normy ASTM B48-00(2021)e1 :
This specification covers soft or annealed bare copper wire, rectangular or square in shape with rounded corners. For the purpose of this specification, the wire shall be classified as Type A and Type B. The wire shall be annealed after the last drawing or rolling to size and shape, and shall be processed as to produce a uniformly soft product with a clean surface. The finished wire shall not contain joints except such as have passed through drawing dies. Necessary joints in the wire and rods prior to final drawing shall be made in accordance with good commercial practice. Material dimensions, such as thickness and width, shall not vary from that specified by more than the amounts prescribed. The wire shall conform to the requirements for rounded corners and rounded edges. The material shall undergo physical tests, and shall conform to the elongation and bending requirements. For the purpose of this specification, all wire dimensions and properties shall be considered ac occurring at the internationally standardized reference temperature. Nominal cross-sectional areas shall be calculated by subtracting the area reductions due to rounded corners or rounded edges. Nominal mass/unit length and lengths shall be calculated from the nominal wire dimensions in accordance with the following equations and shall be rounded off in the final value only. Electrical resistivity shall be determined on representative samples by resistance measurements. Tests to determine conformance to electrical resistance requirements shall be made on the uninsulated conductor.

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 AFor all applications except those involving edgewise bending. 1.2.2?Type BFor 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. |
