Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 457-2003 "double zero foil cold-rolled strip." Compared with this standard YS/T 457-2003, the main differences are as follows. --- Increasing the thickness of 0.01mm ~ 0.20mm single zero foil and foil with non-zero cold-rolled strip; --- Delete the definition of "double zero aluminum foil" in; --- Modify the definition of convex and flatness; --- Increased 1050,1060,3003,3102,3104,3105,5A02,5052,8006,8021,8111 grades; --- Increased H14, H16, H18 state 1050,1060,3105 grades; H18 state 3102,3104 grades; 5A02, O, H14 grade status 5052; 8006 grades H14, H16 state; 8021 brands H14 state; 3003,8111 Grades O, H14, H16, H18 state; --- Modified tag example; --- Amend the relevant provisions of the chemical composition; --- Tightened size deviation; --- Increasing the single zero foil, foil with non-zero mechanical properties of cold-rolled strip, foil, double zero with the mechanical properties of cold-rolled strip has been adjusted; --- Tightened the double zero foil cold-rolled strip hydrogen content requirements, increasing the single zero foil, foil with non-zero cold rolled strip hydrogen content requirements; --- Increasing the strip method for determination of hydrogen; --- Increased low magnification requirements; --- Remove the casting (casting) grain size related provisions; --- Increased surface roughness; --- Modify the test result of the determination of the relevant provisions. The standard reference method using redrafted EN12482.1998 "and rolled aluminum and aluminum alloys for general purpose use blanks" EN485.1.2008 "aluminum and aluminum alloy sheet, strip and plank - Part 1. Technical conditions for inspection and delivery", EN485.2.2008 "Aluminum and aluminum alloy sheet, strip and plank - Part 2. mechanical properties", EN485.4.1994 "aluminum and aluminum alloy sheet, strip and Planks Part 4. cold-rolled product size and shape bias "be revised. This standard EN12482.1998, EN485.1.2008, EN485.2.2008, EN485.4.1994 is non-equivalent. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
