GB/T 3048.2-2007 Test methods for electrical properties of electric cables and wires—Part 2:Test of electrical resistivity of metallic materials
Abstract
This part of GB/T 3048 specifies the terms and definitions, test equipment, sample preparation, test procedures, test results, and calculations and test records for the electrical resistivity of metal materials. The test methods specified in this part are applicable to the determination of the volume resistivity and mass resistivity of solid (non-stranded) copper, aluminum, and their alloy metal conductors and resistive materials, as well as the determination of the unit length resistance of solid metal conductors (with a uniform cross-sectional area). The methods provided in this part are a reference and routine test method for determining the electrical resistivity of solid (non-stranded) materials under standard conditions within the range of (0.01～2.0)Ω·mm2/m (μΩ·m). This part should be used in conjunction with GB/T 3048.1.
