18、 at the latest by October 2003, and conflicting national standards shall be withdrawn at the latest by October 2003. This document supersedes EN 10152:1993. Annex A is normative.

20、. 1 Scope 1.1 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 co
21、il form), sheet, slit strip or cut lengths obtained from slit strip or sheet. 1.2 This European Standard can 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
22、 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 EN 10268, or other microalloyed steels, high strength IF(without interstitial atoms) steels, p
23、hosphorous alloyed steels and bake-hardening steels, dual phase steels, general purpose structural steels. 1.3 By special agreement at the time of enquiry and order this European Standard can be applied to continuously electrolytic zinc coated hot-rolled steel flat products (e.g. according to EN 100
24、25, EN 10111, EN 10149-1 to EN 10149-3, etc.). EN 10152:2003 (E) 4 1.4 The coating masses, surface qualities and surface finishes are given in 6.9, 6.11 and Table 2. As the mass of the zinc coating applied is relatively small, the material is not intended to withstand outside exposure without furthe
25、r chemical treatment and painting. 1.5 This European Standard is not applicable to hot-dip zinc coated steel strip and sheet (see EN 10142 and EN 10147); continuously organic coated steel flat products (see EN 10169-1, ENV 10169-2 and prEN 10169-3). 2 Normative references This European Standard inco

32、olution by the use of an electric current NOTE Flat products can have a zinc coating on one or both surfaces. If both surfaces are zinc coated, a different coating thickness can be applied on each side (this process being referred to as differential zinc coating). 4 Classification and designation 4.
33、1 Classification The steel grades specified in this standard are classified in accordance with EN 10020 as non-alloy quality steels (DC01, DC03, DC04, DC05) and alloy quality steel (DC06) and by their increasing suitability for cold forming as follows: DC01: drawing quality; DC03: deep drawing quali
34、ty; DC04, DC05: special deep drawing quality DC06: extra deep drawing quality. 4.2 Designation 4.2.1 The steel names are allocated in accordance with EN 10027-1 and CR 10260; the steel numbers are allocated in accordance with EN 10027-2. 4.2.2 The products covered by this European Standard shall be
35、designated as follows in the order given: a) Type of product (e. g. strip, sheet, cut length), b) Number of this standard (EN 10152), c) Steel name or steel number and symbol for the type of electrolytical coating (see Table 1), d) Numbers denoting the nominal coating thickness on each surface (e. g
