Electrolytically zinc 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 above or equal to 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.

Produits plats en acier, laminés à froid, revêtus de zinc par voie électrolytique pour formage à froid - Conditions techniques de livraison
La présente Norme européenne définit les prescriptions relatives aux produits plats laminés à froid revêtus de zinc en continu par voie électrolytique (ou produit par un autre procédé sur un support laminé à froid), en aciers à bas carbone aptes au formage à froid selon les indications du Tableau 1, en largeurs laminées ≥ 600 mm et en épaisseurs comprises entre 0,35 mm et 3 mm inclus, livrés sous forme de bandes (en bobines), de tôles, de bandes refendues coupées à longueur ou non ou dans des tôles.
NOTE 1 La présente Norme européenne peut également s'appliquer aux produits plats revêtus de zinc en continu, par voie électrolytique, en :
a) aciers conformes à l'EN 10139 (feuillards laminés à froid en largeurs de laminage < 600 mm),
b) aciers normalement caractérisés par une valeur minimale de limite d'élasticité ou de résistance à la traction en plus de leur aptitude au formage et par exemple ;
1) aciers à haute limite d'élasticité et à formabilité améliorée conformes à l’EN 10268 (produits plats laminés à froid) ;
2) aciers multiphasés (laminés à froid ou laminés à chaud) conformes au EN 10338 ;
3) 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 produits plats laminés à chaud revêtus de zinc en continu par voie électrolytique (par exemple, conforme aux normes EN 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.
NOTE 4 Les produits conforme à cette norme européenne peuvent être utilisés comme substrats pour les produits plats à revêtement organique spécifiés dans l'EN 10169 pour des applications dans la construction et la mécanique générale.
Elektrolizno cinkani hladno valjani ploščati izdelki iz jekla za hladno preoblikovanje - Tehnični dobavni pogoji
Ta evropski standard določa zahteve za trajno elektrolizno cinkane hladno valjane ploščate izdelke iz jekla z nizko vsebnostjo ogljika, primerne za hladno preoblikovanje v skladu s preglednico 1, z valjano širino vsaj 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 tudi 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 (glej 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.

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.
