Foreword
This document EN 10152:2003 has been prepared by Technical Committee ECISS/TC 27 "Surface coated flat
products - Qualities, dimensions, tolerances and specific tests", the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by October 2003, and conflicting national standards shall be withdrawn at the latest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.
This document includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,
Slovakia, Spain, Sweden, Switzerland and the United Kingdom.
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 coil 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 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,
phosphorous 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 10025, EN 10111,
EN 10149-1 to EN 10149-3, etc.).

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
further 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).

EN 10152:2003 (E)
6.2 Steelmaking and manufacturing processes
Unless otherwise agreed at the time of enquiry and order, the steelmaking and manufacturing processes are left to
the discretion of the manufacturer. The purchaser shall be informed of these processes, if he requires it.
6.3 Deoxidation
The method of deoxidation shall be in accordance with that specified in Table 1.
6.4 Chemical composition
The chemical composition based on ladle analysis shall be as given in Table 1.
6.5 Delivery condition
The steel substrates are normally supplied in the skin-passed condition. By agreement at the time of enquiry and
order non skin-passed products may be supplied.
6.6 Choice of properties
The products covered by this standard shall comply with the requirements of Table 1. By agreement at the time of
enquiry and order they may be delivered as suitable for making a particular part; in this case a maximum
percentage of scrap may be agreed and acceptance on the basis of mechanical properties is not applicable.
6.7 Mechanical properties
6.7.1 The mechanical properties are given in Table 1; they apply only to skin-passed products.
NOTE The properties in Table 1 are those specified for cold rolled non-coated low carbon steel flat products according to
EN 10130 with the exception of the R , A and n values for the grades DC04+ZE, DC05+ZE and DC06+ZE which have been
e 80 90
altered with respect to the influence of the electrolytical treatment on those properties.
The mechanical properties are valid for the period specified in Table 1 from the date on which the products are
made available. The date of availability shall be notified to the purchaser with reasonable prior notice compatible
with the validity of the mechanical properties. Prolonged storage of products of grade DC01+ZE could result in
some change in the mechanical properties leading to a reduction in formability.
6.7.2 The tensile test values apply to transverse samples and relate to the test piece cross-section without zinc
coating.
