For hardness test of copper in Brinell hardness tester, the diameter of ball is ___________ Correct Answer 5mm

ASTM E-10 is a standard test for determining the Brinell hardness of metallic materials. The load applied in this test is usually 3,000, 1,500, or 500 kgf, so that the diameter of the indentation is 5 mm.
