European foreword
This document (prEN 10152:2015) has been prepared by Technical Committee ECISS/TC 109 “Coated
and uncoated flat products to be used for cold forming”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 10152:2009.

1 Scope
This European Standard specifies requirements for continuously electrolytic (or produced with an
alternative process on cold rolled finish substrate) 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 below and including 3 mm, delivered as strip (in coil form), sheet, slit strip or cut lengths
obtained from slit strip or sheet.
NOTE 1 This European Standard can also be applied to continuously electrolytic zinc coated flat products of:
a) steels according to EN 10139 (cold rolled strip in rolled widths < 600 mm),
b) steels normally characterized by minimum yield strength or minimum tensile strength values in
addition to formability parameters, e.g.
1) steels with high yield strength and improved formability according to EN 10268 (cold rolled
flat products),
2) multiphase steels (cold rolled or hot rolled) according to prEN 10338,
3) steels for construction according to national or regional standards (see e.g. DIN 1623).
NOTE 2 By 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 10025–1 and −2, EN 10111, EN 10149–
1 to EN 10149–3, etc.).
NOTE 3 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.
NOTE 4 The products covered by this European Standard can be used as substrates for organic coated flat
products specified in EN 10169 for building and general engineering applications.

3.1
electrolytic zinc coating (ZE)
application of a zinc coating by electrolysis on a suitably prepared steel surface from an aqueous zinc
salt solution by the use of an electric current
Note 1 to entry 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
4.1 Classification
The steel grades specified in this European Standard are classified in accordance with
EN 10020:2000 as non-alloy quality steels (DC01, DC03, DC04, DC05) and alloy quality steels (DC06,
DC07) and by their increasing suitability for cold forming as follows:
— DC01: drawing quality;
— DC03: deep drawing quality;
— DC04, DC05: special deep drawing quality;
— DC06: extra deep drawing quality;
— DC07: super deep drawing quality.
4.2 Designation
4.2.1 The steel names are allocated in accordance with EN 10027-1. The steel numbers are allocated
