1 This European Standard specifies requirements for continuously electrolytic zinc coated cold rolled flat products of low carbon steels suitable for cold forming according to table 1 in rolled widths
> 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.
2 This European Standard may also be applied to continuously electrolytic zinc coated cold rolled flat products of
a) steels according to EN 10139 (cold rolled strip in rolled widths < 600 mm);
b) other types of low carbon steel for cold forming;
c) steels normally characterized by minimum yield strength values in addition to formability parameters, e.g.
— steels with high yield strength and improved formability according to EURONORM 149, Part 4, or other microalloyed steels;
— phosphorous alloyed steels and bake-hardening steels;
— general purpose structural steels.
3 By special agreement at the time of ordering this European Standard may be applied to continuously electrolytic zinc coated hot-rolled steel flat products (e.g. according to EN 10025, EURONORM 111, EURONORM 149 : Part 1 to Part 3 etc.).
4 The coating masses, surface qualities and surface finishes are given in 5.9, 5.11 and table 2. As the mass of the zinc coating applied is relatively small, the material is not intended to withstand outside exposure without further chemical treatment and painting.
5 This European Standard is not applicable to
— hot-dip zinc coated steel sheet and strip (see EN 10142 and EN 10147);
— continuously organic coated steel flat products (see EN 10169).
