Standard Test Method for Resistivity of Electrical Conductor Materials
Also Known As:
The ASTM B193-20 standard provides a detailed procedure for determining the electrical resistivity of metallic electrical conductor materials. The standard outlines the definition of resistivity and provides equations for calculating both volume resistivity and weight resistivity.
To ensure accurate measurements, the standard specifies the use of an apparatus with a circuit configuration and instrumentation that has a resistance measurement capability of the prescribed accuracy. The test specimen requirements are outlined, including the determination of dimensions (such as length and cross-section), weight, and density.
The test procedure includes the measurement of resistance using the specified apparatus. Additionally, the standard provides a formula for calculating the corrected resistance when the measurement is made at a temperature other than a reference temperature.
The standard does not provide a statement of precision or planned work to develop such a statement. However, it states that there is no bias in the value for resistivity determined by this test method.
