ASTM E476

ASTM E476 is a standard test method used to measure the electrical resistivity or conductivity of materials, typically metals or conductive coatings. It provides procedures to determine how easily electric current can pass through a material, which is important for assessing corrosion resistance, material quality, or performance in electrical applications. The method involves applying a known current and measuring the resulting voltage, then calculating resistivity from these measurements. This standardized approach ensures consistent and accurate results, helping engineers and scientists evaluate material properties for various industrial uses.
