NOTE 1   Other thicknesses can be ordered upon agreement.
This document applies to coils and sheets cut from coils in nominal minimum widths of 600 mm.
NOTE 2   Standard width coils for specific uses, e.g. tabstock, can be slit into narrow strip for supply in coil form.

Einfach kaltgewalzte Verpackungsblecherzeugnisse werden in Nenndicken von 0,16 mm bis 0,49 mm in Stufen von 0,005 mm geliefert. Doppeltreduzierte Verpackungsblecherzeugnisse werden in Nenndicken von 0,12 mm bis 0,29 mm in Stufen von 0,005 mm geliefert.
ANMERKUNG 1   Auf Anfrage können auch andere Dicken bestellt werden.
Dieses Dokument gilt für Band in Rollen und für aus Band geschnittene Tafeln in Nennbreiten von mindestens 600 mm.
ANMERKUNG 2   Für besondere Anwendungen, z. B. "Laschenband", darf das Band auch als durch Längsteilen hergestelltes schmaleres Band in Rollen geliefert werden.

Aciers pour emballage laminés à froid - Fer blanc électrolytique et acier revêtu de chrome/d'oxyde de chrome électrolytique

Le présent document spécifie les exigences relatives aux aciers pour emballage sous la forme de feuilles ou de bobines. Les aciers pour emballage sont constitués d’acier doux à faible teneur en carbone à simple et double laminage recouvert par électrolyse d’étain (fer blanc) ou de chrome ou d’oxyde de chrome (ECCS ou ECCS-RC) (voir 3.3).
Les aciers pour emballage à simple laminage sont spécifiés dans des épaisseurs nominales qui sont des multiples de 0,005 mm à partir de 0,16 mm jusqu’à 0,49 mm inclus. Les aciers pour emballage à double laminage sont spécifiés dans des épaisseurs nominales qui sont des multiples de 0,005 mm à partir de 0,12 mm jusqu’à 0,29 mm inclus.
NOTE 1   Après accord, il est possible de commander d’autres épaisseurs.
Le présent document s’applique aux bobines et aux feuilles découpées dans des bobines dont les largeurs nominales sont égales à 600 mm au minimum.
NOTE 2   Les bobines de largeurs normalisées pour usages spéciaux, tels que feuillard, peuvent être découpées en bandes refendues à longueur pour conditionnement en bobines.

European foreword

This document (prEN 10202:2021) has been prepared by Technical Committee CEN/TC 459/SC 9

“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 10202:2001.

In comparison with the previous edition, the following technical modifications have been made:

— normative references have been updated;

— revision of the definition of electrolytic chromium coated steel with the addition of the symbol ECCS-

RC which allows the use of a trivalent process;

— rewording of Clause 5 with the split into mandatory information (5.1) and options (5.2);

— modification of Clause 6 with the rewording of 6.1 and the addition of 6.2 and 6.3 about annealing

and finish respectively;
— Table 1 has been updated;
— major modifications of 6.4 about passivation;

— addition of a new subclause 6.6 on imperfections that includes 6.6.1 and 6.6.2 for coils and sheets

respectively;

— major modifications of Clause 7 about coatings including changes of Table 2, Table 3 and Table 4;

— major modifications of Clause 8 about mechanical properties with the addition of stress-strain curves

for batch and continuous annealed material, curve showing the plateau height for continuous

annealed material and stress-strain curves for the determination of the yield strength of some

continuous annealed grades;

— removal of the tensile strength values from Table 5 and transfer into informative Annex J;

— modification of 9.4.6 about test method for centre fullness;
— modifications of the ordering of Annexes;
— new Annex I about tensile testing conditions in case of dispute;
— deletion of the Annex giving the previous designations.
