21、 is evidence that the test specimenis defective or is not representative of the lot of material,retesting shall be performed in accordance with Test MethodsE8/E8M.8. Bend Properties8.1 Limits:8.1.1 Class 20A, 25A and Class 30A bars shall withstand aflatwise bend at room temperature, through an angle
22、 of 90around mandrel having a radius shown in Table 2 withoutcracking or obvious orange peel or evidence of slivers or otherimperfections on the surface (the cladding layer), or blisterphenomenon inside the bending width. In macrostructure, nearthe curved areas, interface holes or cracks should not
23、appear,and no separation phenomenon between the cladding layer andthe aluminum core. For a flatwise bend, the mandrel shall be90 from the rolling direction, and across the greater (width)dimension of the bar. The required 90 bend shall be in therolling direction. This is a longitudinal guided bend a
