1.1?This specification covers concentric-lay-stranded conductors, made from round aluminum-alloy 6201-T81 (hard: solution heat-treated, cold worked, and then artificially aged) wires, for use for electrical purposes. These conductors shall be constructed with a central core surrounded by one or more layers of helically laid wires (Explanatory Notes 1 and 2). Note 1:?The aluminum alloy and temper designations conform to
ANSI H35.1/H35.1[M]. Aluminum-alloy 6201 corresponds to Unified
Numbering System alloy A96201 in accordance with Practice
E527.
1.2?The values stated in inch-pound units or SI units are to be regarded separately as standard. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 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. |
