This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 459/SC 9.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

1 Scope
This document specifies requirements for blackplate product in the form of coils intended for direct use
and mostly for the production of electrolytically zinc coated plate, or coils electrolytically coated with
either tin (tinplate) or chromium/chromium oxide (ECCS or ECCS-RC).
Blackplate can be a single or double reduced product and is specified in nominal thicknesses that are
multiples of 0,005 mm from typical 0,10 mm up to 0,60 mm.
This document applies to coils in nominal minimum widths of 600 mm.
In addition to this document, the general technical delivery conditions of EN 10021 apply.
NOTE Standard width coils for specific uses, e.g. tab stock, can be slit into narrow strip for supply in coil form.
