ISO 11951:2016规定了按照ISO 11949或ISO 11950制造电解马口铁或电解铬/氧化铬涂层钢（ECCS）的线圈形式的单板和双板冷轧黑板的要求。 单块冷轧黑板的标称厚度通常为0005 mm的倍数，从0150 mm到0600 mm（含0600 mm）。双冷缩径黑板的标称厚度通常为0005 mm的倍数，从0100 mm到0360 mm（包括0360 mm）。 ISO 11951:2016适用于标称最小轧制宽度为600 mm[1]且边缘经过修整或未经修整的线圈。 [1] 经买方和制造商同意，可采用500 mm的标称最小轧制宽度。

ISO 11951:2016 specifies requirements for single and double cold-reduced blackplate in the form of coils which are intended for manufacturing electrolytic tinplate or electrolytic chromium/chromium oxide-coated steel (ECCS) in accordance with ISO 11949 or ISO 11950. Single cold-reduced blackplate 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 is generally specified in nominal thicknesses that are multiples of 0,005 mm, from 0,100 mm up to and including 0,360 mm. ISO 11951:2016 applies to coils in nominal minimum rolling widths of 600 mm[1] with either trimmed or untrimmed edges. [1] Nominal minimum rolling widths of 500 mm may be applied by agreement between the purchaser and the manufacturer.
