ISO 20482:2013规定了一种标准试验方法,用于测定厚度为0.1 mm至2 mm、宽度为90 mm或更大的金属板材和带材在拉伸成形中承受塑性变形的能力。
对于较厚且只有较窄条带可用的材料,提供指定尺寸的工具,在这种情况下使用下标,如表1所示。
ISO 20482:2013 specifies a standard test method for determining the ability of metallic sheets and strips having a thickness from 0,1 mm up to 2 mm and a width of 90 mm or greater to undergo plastic deformation in stretch forming.
For materials that are thicker and when only narrower strips are available, tools of specified dimensions are provided, in which case subscripts are used, as shown in Table 1.
