NOTE- In all other elements (other than 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 exclusión of any ítem whose value this indicated individually.
a To including silver, to a máximum 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.

a In the case of a rectangular tube, the greater dimension between faces determines the applicable thickness tolerance for all wall thicknesses.
b Tolerances on wall thickness are defined as the maximum deviation of wall thickness at any point, expressed as a percentage of the nominal wall thickness
c If all positive and negative tolerances are required, the values given must be multiplied by two.
