Electrolytically zincdip coated cold rolled steel flat products for cold forming - Technical delivery conditions
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. 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.
Elektrolytisch verzinkte kaltgewalzte Flacherzeugnisse aus Stahl zum Kaltumformen - Technische Lieferbedingungen
Diese Europäische Norm legt die Anforderungen an kontinuierlich elektrolytisch verzinkte, kaltgewalzte Flacherzeugnisse
aus weichen Stählen zum Kaltumformen nach Tabelle 1 in gewalzten Breiten ≥ 600 mm und mit
einer Dicke von 0,35 mm bis 3 mm fest, die als Band (in Rollen), Blech, längs geteiltes Band oder daraus
abgelängte Stäbe geliefert werden.
ANMERKUNG 1 Diese Europäische Norm kann auch auf kontinuierlich elektrolytisch verzinkte, kaltgewalzte
Flacherzeugnisse aus
a) Stählen nach EN 10139 (Kaltband in Walzbreiten < 600 mm),
b) Stählen, die üblicherweise in Ergänzung zu den Anforderungen an die Umformbarkeit durch Mindestwerte für die
Streckgrenze oder Zugfestigkeit gekennzeichnet sind, z. B.
⎯ Stähle mit hoher Streckgrenze und verbesserter Umformbarkeit nach EN 10268 (kaltgewalzte Flacherzeugnisse),
⎯ Mehrphasenstähle (kaltgewalzt oder warmgewalzt) nach prEN 10338,
⎯ Stähle für die Anwendung im Bauwesen nach nationalen oder regionalen Normen (siehe z. B. DIN 1623)
angewendet werden.
ANMERKUNG 2 Nach Vereinbarung bei der Anfrage und Bestellung kann diese Europäische Norm auf kontinuierlich
elektrolytisch verzinkte, warmgewalzte Flacherzeugnisse aus Stahl (z. B. nach EN 10025, EN 10111, EN 10149-1 bis
EN 10149-3 usw.) angewendet werden.
ANMERKUNG 3 Da die Masse der Zinkauflage verhältnismäßig klein ist, sind die Erzeugnisse nicht ohne weitere
chemische Behandlung und Beschichtungen für die Verwendung im Außeneinsatz vorzusehen.

froid) ;
- aciers multiphasés (laminés à froid ou laminés à chaud) conformes au prEN 10338 ;
- aciers pour la construction conformes aux normes nationales ou régionales (voir par exemple DIN 1623).
NOTE 2 Par accord au moment de l’appel d’offres et à la commande, cette Norme européenne peut être appliquée aux

10025-1 et -2, EN 10111, EN 10149-1 à EN 10149-3, etc.).
NOTE 3 Comme la masse du revêtement de zinc appliqué est relativement faible, le matériau n'est pas censé résister
à une exposition extérieure sans traitement chimique supplémentaire et application de peinture.
Elektrolizno cinkani hladno valjani ploščati izdelki za hladno preoblikovanje - Tehnični dobavni pogoji
Ta evropski standard določa zahteve za trajno elektrolizno cinkane hladno valjane ploščate izdelke iz maloogljičnega jekla, primerne za hladno preoblikovanje v skladu s preglednico 1, z valjano širino ≥ 600 mm in debelino od 0,35 mm do vključno 3 mm, dobavljene v obliki traka (zvitki), pločevine, razrezanega traka ali narezanih dolžin iz razrezanega traka oziroma pločevine. OPOMBA 1: Ta evropski standard se lahko uporablja za trajno elektrolizno cinkane ploščate izdelke iz:
a) jekla v skladu s standardom EN 10139 (hladno valjan trak v valjanih širinah < 600 mm),
b) jekla, ki ga poleg parametrov oblikovalnosti običajno opredeljujejo najmanjše vrednosti meje tečenja ali natezne trdnosti , npr.
1) jekla z visoko mejo tečenja in izboljšano oblikovalnostjo v skladu s standardom EN 10268 (hladno valjani ploščati izdelki),
2) večfazna jekla (hladno valjana ali vroče valjana) v skladu s standardom prEN 10338,
3) jekla za gradnjo v skladu z nacionalnimi ali regionalnimi standardi (glejte npr. DIN 1623).
OPOMBA 2: Ta evropski standard je mogoče po dogovoru v času povpraševanja in naročila uporabiti za trajno elektrolizno cinkane vroče valjane ploščate izdelke (npr. v skladu s standardi EN 10025-1 in -2, EN 10111, EN 10149-1 do EN 10149-3 itd.). OPOMBA 3: Ker je masa nanesenega cinkovega premaza sorazmerno majhna, material ni namenjen za uporabo na prostem brez dodatne kemične obdelave in barvanja.

The date of availability shall be notified to the purchaser with reasonable prior notice compatible with the validity of the mechanical properties.
NOTE 2 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. 6.7.3 Strain ratio r90 (see Table 1) and the strain hardening exponent n90 shall be determined in the range of homogeneous deformation, within the strain range of 10 % to 20 %.
