The International Annealed Copper Standard (IACS) is a standard established in 1914 by the United States Department of Commerce. [1] It is an empirically derived standard value for the electrical conductivity of commercially available copper.
Conductivity is generally specified relative to the 1913 International Annealed Copper Standard of 5.8 × 10 7 S/m. Advances in the refining process now yield OF and ETP copper that can meet or exceed 101% of this standard. (Ultra-pure copper has a conductivity of 5.865 × 10 7 S/m, 102.75% IACS.) Note that OF and ETP coppers have identical ...
Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.
The electrical conductivity of silver is 106% of that of annealed copper on the IACS scale, and the electrical resistivity of silver = 15.9 nΩ•m at 20 °C. [ 14 ] [ 15 ] The high cost of silver combined with its low tensile strength limits its use to special applications, such as joint plating and sliding contact surfaces, and plating for ...
