【国外标准】 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.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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.
