Continuously hot-dip coated strip and sheet of structural steels - Technical delivery conditions

1.1   This European Standard specifies requirements for continuously hot-dip coated products made of structural steels coated with zinc (Z), zinc-iron alloy (ZF), zinc-aluminium alloy (ZA), aluminium-zinc alloy (AZ) and aluminium-silicon alloy (AS) (see Table 1) with thicknesses from 0,35 mm up to 3,0 mm unless otherwise agreed (see 1.2). The thickness is the final thickness of the delivered product after coating.
This European Standard applies to strip of all widths and to sheets cut from it (= 600 mm width) and cut lengths
(< 600 mm width).
1.2   If agreed at the time of enquiry and order, this European Standard may also be applied to continuously hot-dip coated flat products in thicknesses > 3,0 mm. In this case the mechanical property, adhesion of coating and surface condition requirements shall also be agreed at the time of enquiry and order.
1.3   The products covered by this European Standard are mainly used where minimum yield strength and corrosion resistance are the most important factors. Corrosion resistance of the alloy is proportional to the coating thickness, hence to its mass (see also 7.3.2).
NOTE   +ZF coated products should not be used without additional organic coating.
1.4   This European Standard is not applicable to:
· continuously hot-dip coated flat products of low-carbon steel strip and sheet for cold forming (see prEN 10327);
· electrolytic galvanized cold rolled steel flat products (see EN 10152);
· continuously organic coated (coil coated) flat steel products (see EN 10169-1, ENV 10169-2 and
EN 10169-3);
· continuously hot-dip coated strip and sheet of steels with higher yield strength for cold forming (see EN 10292).

Kontinuierlich schmelztauchveredeltes Band und Blech aus Baustählen - Technische Lieferbedingungen

1.1   Dieses Dokument legt die Anforderungen an kontinuierlich schmelztauchveredelte Flacherzeugnisse aus Baustählen mit Überzügen aus Zink (Z), Zink-Eisen-Legierung (ZF), Zink-Aluminium-Legierung (ZA), Aluminium-Zink-Legierung (AZ) und Aluminium-Silicium-Legierung (AS) (siehe Tabelle 1) in Dicken von
0,35 mm bis 3,0 mm fest, falls nicht anders vereinbart (siehe 1.2). Als Dicke gilt die Enddicke des gelieferten Erzeugnisses nach dem Schmelztauchveredeln.
Dieses Dokument gilt für Band aller Breiten sowie für daraus abgelängte Bleche (= 600 mm Breite) und Stäbe (< 600 mm Breite).
1.2   Nach Vereinbarung bei der Anfrage und Bestellung kann dieses Dokument auch auf kontinuierlich schmelztauchveredelte Flacherzeugnisse in Dicken > 3,0 mm angewendet werden. Die Anforderungen an die mechanischen Eigenschaften, die Haftung des Überzugs und die Oberflächenbeschaffenheit sind in diesem Fall ebenfalls bei der Anfrage und Bestellung zu vereinbaren.
1.3   Die Erzeugnisse nach diesem Dokument eignen sich für Verwendungszwecke, bei denen die Mindeststreckgrenze und die Korrosionsbeständigkeit von vorrangiger Bedeutung sind. Der durch den Überzug bewirkte Korrosionsschutz ist der Überzugsdicke und damit der Auflagenmasse proportional (siehe auch 7.3.2).
ANMERKUNG   Erzeugnisse mit Überzug + ZF sollten nicht ohne einen zusätzlichen organischen Überzug verwendet werden.
1.4   Dieses Dokument Norm gilt nicht für
·   kontinuierlich schmelztauchveredelte Flacherzeugnisse aus weichen Stählen zum Kaltumformen (siehe
EN 10327);
·   elektrolytisch verzinkte kaltgewalzte Flacherzeugnisse aus Stahl (siehe EN 10152);
·   kontinuierlich organisch beschichtete (bandbeschichtete) Flacherzeugnisse aus Stahl (siehe EN 10169-1,
ENV 10169-2 und EN 10169-3);
·   kontinuierlich schmelztauchveredeltes Band und Blech aus Stählen mit hoher Streckgrenze zum Kaltumformen (siehe EN 10292).

Bandes et tôles en aciers de construction doux revêtues en continu par immersion à chaud - Conditions techniques de livraison

1.1   Le présent document a pour objet de spécifier les exigences relatives aux produits en acier de construction revêtus par immersion à chaud en continu de zinc (Z), d'alliage de zinc et de fer (ZF), d'alliage de zinc et d'aluminium (ZA), d'alliage d'aluminium et de zinc (AZ) et d'alliage d'aluminium et de silicium (AS) (voir Tableau 1), avec des épaisseurs allant de 0,35 mm à 3,0 mm sauf indication contraire (voir 1.2). L'épaisseur considérée est l'épaisseur finale du produit livré après revêtement.
Le présent document est applicable aux bandes et bandes refendues de toutes largeurs (largeur ³ 600 mm) de même qu'aux feuilles et aux flans  qui y sont découpées (largeur < 600 mm).
1.2   Par accord lors de la commande, le présent document peut également être utilisé pour les produits plats en acier revêtus par immersion à chaud en continu d'épaisseur > 3,0 mm. Dans ce cas, les propriétés mécaniques et les caractéristiques d'adhérence du revêtement et de finition doivent également faire l'objet d'un accord à la commande.
1.3   Les produits conformes au présent document sont principalement utilisés lorsque la limite d'élasticité minimale et la résistance à la corrosion sont les facteurs primordiaux. La résistance du revêtement à la corrosion est proportionnelle à la masse du revêtement pour une famille de revêtements donnée (voir aussi 7.3.2).
NOTE   L'utilisation de produits revêtus +ZF n'est pas recommandée sans revêtement organique supplémentaire.
1.4   Le présent document ne s'applique pas :
-   aux bandes et tôles en acier doux revêtues par immersion à chaud en continu pour formage à froid (voir EN 10327) ;
-   aux produits plats en acier, laminés à froid, revêtus de zinc par voie électrolytique (voir EN 10152) ;
-   aux produits plats en acier revêtus en continu de matières organiques (prélaqués) (voir EN 10169-1, ENV 10169-2 et EN 10169-3) ;
