35、 or coils forsubsequent cutting into sheets. Tinmill products consist of single and double reduced low carbon mildsteel electrolytically coated with either tin (tinplate) or chromium/chromium oxide (ECCS).Single reduced tinmill products are specified in nominal thicknesses that are multiples of 0,00

36、5 mmfrom 0,17 mm up to and including 0,49 mm. Double reduced tinmill products are specified in nominalthicknesses that are multiples of 0,005 mm from 0,13 mm up to and including 0,29 mm.This European Standard applies to coils and sheets cut from coils in nominal minimum widths of600 mm.NOTE Standard

37、 width coils for specific uses, e.g. tabstock, may be slit into narrow strip for supply in coilform.Page 4EN 10202:20012 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from otherpublications.
