This document specifies requirements for tinmill products in the form of sheets or coils. Tinmill products consist of single and double reduced low carbon mild steel electrolytically coated with either tin (tinplate) or chromium/chromium oxide (ECCS) or (ECCS-RC) (see 3.3). Single reduced tinmill products are specified in nominal thicknesses that are multiples of 0,005 mm from 0,16 mm up to and including 0,49 mm. Double reduced tinmill products are specified in nominal thicknesses that are multiples of 0,005 mm from 0,12 mm up to and including 0,29 mm. 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.
