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. |
