ISO 11950:2016规定了薄板或线圈形式的单次和双次冷还原电解铬/氧化铬涂层钢（ECCS）的要求。 单个冷缩ECC的标称厚度通常为0005 mm的倍数，从0150 mm到0600 mm（包括0600 mm）。双冷缩径ECCS的标称厚度通常为0005 mm的倍数，从0100 mm到0360 mm（包括0360 mm）。 ISO 11950:2016适用于从标称最小轧制宽度为600 mm[1]的卷材上切割的卷材和板材。 [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 11950:2016 specifies requirements for single and double cold-reduced electrolytic chromium/chromium oxide-coated steel (ECCS) in the form of sheets or coils. Single cold-reduced ECCS 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 ECCS 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 11950:2016 applies to coils and sheets cut from coils in nominal minimum rolling widths of 600 mm[1]. [1] Nominal minimum rolling widths of 500 mm may be applied by agreement between the purchaser and the manufacturer.
