| Resumen: | This test method covers the determination of the electrical resistivity of metallic electrical conductor material. Weight resistivity accuracy may be adversely affected by possible inaccuracies in the assumed density of the conductor. The definition of resistivity and the equations for calculating volume resistivity and weight resistivity are given. Resistance shall be measured using an apparatus with a circuit configuration and instrumentation that has a resistance measurement capability of the prescribed accuracy. The test specimen requirements and the test procedure including: (1) determination of dimensions (such as length and cross-section), weight, and density, and (2) resistance measurement are detailed. The formula for calculating the corrected resistance, when the measurement is made at any temperature other than a reference temperature, is given. No statement of precision has been made and no work has been planned to develop such a statement. This test method has no bias because the value for resistivity is determined solely in terms of this test method. |

| Scope: | 1.1 This test method covers the determination of the electrical resistivity of metallic electrical conductor material. It provides for an accuracy of ±0.30 % on test specimens having a resistance of 0.00001 Ω (10 μΩ) or more. Weight resistivity accuracy may be adversely affected by possible inaccuracies in the assumed density of the conductor. 1.2 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. 1.3 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. |
