ASTM B263 – Standard Test Method for Determination of Cross-Sectional Area of Stranded Conductors
This test method covers the standard procedure for determining the cross-sectional area of stranded conductors by the mass method. The apparatus shall consist of a balance for mass measurement, a steel scale for length measurement, and a jig or equivalent equipment for cutting the conductor to length and at right angles to its axis. Cross-sectional area of stranded conductors such as those with only one type of conducting material, cored annular conductors and steel-reinforced aluminum conductors, composite copper and copper-covered steel conductors, and composite aluminum 1350 and aluminum alloy 6201 conductor shall be calculated.
1.1 This test method covers the procedure for determining the cross-sectional area of stranded conductors by the mass method.
1.2 The values stated in inch-pound or SI units are to be regarded separately as the 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.
