This document applies to:

—     single cold-reduced blackplate which is generally specified in nominal thicknesses that are multiples of 0,005 mm from 0,150 mm up to and including 0,600 mm;

—     double cold-reduced blackplate which is generally specified in nominal thicknesses that are multiples of 0,005 mm, from 0,100 mm up to and including 0,390 mm.

This document applies to coils in nominal minimum rolling widths of 600 mm¹⁾ with either trimmed or untrimmed edges.
