Details requirements for continuously electrolytic zinc-nickel coated cold rolled flat products of low carbon steels suitable for cold forming according to Table 1 and Table 2 in rolled widths equalto or greater than 600 mm and thicknesses from 0.35 mm up to and including 3 mm, delivered as strip (in coil form), sheet, slit strip or cut lengths obtained from slit strip or sheet. The coating is composed of Zn with a Ni-content of 10.5% to 13%. Is also applicable to the coating requirements of continuously electrolytic zinc-nickel coated cold rolled flat products of: a) steels according to EN 10139 - cold rolled strip in rolled widths less than 600 mm. b) other types of low carbon steel for cold forming, c) steels normally characterized by minimum yield strenght values plus formability parameters.
