NOTE - The total of other elements ( different from copper) is defined as the sum of Ag, As, Bi, Cd, Co, Cr, Fe, Mn, Ni, O, P , Pb, S, Sb, Se, Si, Sn, Te and Zn, with the exclusion of any of the elements whose value is indicated individually.
a Including silver (Ag), up to a maximum of 0.015%
b Up to 0.060% of oxygen content is permitted, subject to an agreement between client and supplier.
c Oxygen content must be such that the material complies with the requisites for embrittlement by heating in a hydrogen atmosphere as in Norm En 1976.

NOTE 1 - The IACS % values are calculated as percentages of the normalized value of high conductivity annealed copper, according to those established by the International Electrotechnical Commission. Copper whose volume resistivity is of 0,017 24 Ω x m, at 20ºC, is defined as that corresponding to a conductivity of 100%.
NOTE 2 - 1 MS/m is equivalent to 1 m/(Ω x mm2).
a Calculated with a copper density of 8.89 g/cm3.
b IACS: International Annealed Copper Standard.
