1.1 This International Standard applies to cold-reduced carbon steel strip with a maximum mass fraction of carbon of 0,25 %, furnished to two levels of closer tolerances than cold-reduced carbon steel sheet, with specific quality, specific hardness requirements or mechanical properties, specific edge and specific finish. NOTE This International Standard does not apply to the product in narrow widths known as cold-reduced carbon steel sheet slit from wider widths (ISO 3574), nor does it include cold-reduced carbon steel strip with a mass fraction of carbon over 0,25 % (ISO 4960). 1.2 Cold-reduced carbon steel strip is produced with a maximum mass fraction of the specified carbon not exceeding: ⎯ 0,15 % for material specified to mechanical properties; ⎯ 0,25 % for material specified to temper (hardness) requirements. 1.3 This product is commonly produced in thicknesses of 6 mm and under, and in widths of up to 600 mm, in coils and cut lengths.
