Anotácia textu normy ASTM B496-16(2021) :
This specification covers bare compact round concentric-lay-stranded conductors made from uncoated round copper wires for general use for electrical purposes. Welds and brazes shall be made in rods and wires prior to final drawing. The conductors shall conform to the required construction values of nominal cross-sectional area, diameter, mass per unit length and dc electrical resistance. Tests for the physical and electrical properties of wires composing the conductors shall be made before stranding.

1.1?This specification covers bare compact round concentric-lay-stranded conductors made from uncoated round copper wires for general use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid compacted wires (Explanatory Note 1 and Note 2). 1.2?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. 1.2.1?For density, resistivity, and temperature, the values stated in SI units are to be regarded as standard. 1.3?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. |
