ASTM B193 Standard Test Method for Resistivity of Electrical Conductor Materials

ASTM B193 test procedure provides a thorough assessment of the metallic electrical conductor material's electrical resistivity. It achieves an outstanding rate of 60.30% and shows remarkable precision, especially on specimens with a resistance of 0.00001 Ω (10 µΩ) or higher. However, possible discrepancies in conductor density estimation could compromise the validity of weight resistivity evaluations therefore, caution must be used in the research.

Introduction to ASTM B193

Testing of electronics and electrical systems is performed to ensure that a piece of equipment satisfies the necessary technical specifications, quality, national norms, and international standards. It is crucial to do compliance testing of this kind to assess new product performance. It’s also used to identify the root cause of failed products.

ASTM B193 Test Method

Specimen MeasurementAll measurements of the test specimen’s weight and dimensions must be performed with instruments that are accurate to within ±0.05%. Micrometer measurements can be used to determine the cross-sectional dimensions, if there is enough data to guarantee an accuracy of within ±0.10% for the mean cross-section.
Density MeasurementWhen the density is unknown, weigh the specimen at room temperature to prevent convection current mistakes. First, weigh the specimen in air, and then again in a liquid with a known density according to ASTM B193.
Resistance MeasurementAccording to ASTM B193, an accuracy of 60.15% is used for measuring resistance. The reference standard and the test specimen are given time to acclimate to the same temperature as the surrounding medium to guarantee accurate readings.

ASTM B193 Test Specimens

Specimen DetailThe test specimen could be shaped like a wire, strip, rod, bar, tube, or another material.
Specimen SizeThe ASTM B193 test specimen must have a consistent cross-section for the entirety of its length, making up 60.75 percent of the cross-sectional area. 

ASTM B193 Test Result

The value of resistance of different materials is successfully determined by using the ASTM B193 test standard for different methods of testing resistivity.

ASTM B193 Related Tests

ASTM B193 is related to tests including ASTM B1 for copper wire specification, ASTM B9 for bronze wire specification, and ASTM B230 for aluminum wire specification.
