24、06 EN ISO 9445-2:2010 (E) 3 1 Scope This part of ISO 9445 specifies the tolerances on dimensions and form for continuously cold-rolled stainless steel wide strip and plate/sheet, in thicknesses from 0,30 mm to 8,0 mm and in rolling widths from 600 mm to 2 100 mm. It also applies to slit cold-rolled
25、wide strip in widths less than 600 mm manufactured from wide strip by longitudinal slitting and to cut lengths manufactured from such strip. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited
26、applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
