I just received a test report from a lab we ask to do a surface hardness and core hardness test of a part. They reported the surface & core hardness test results using the Vickers Low Load test. They also reported the "near-surface" test results using the Rockwell test. The part drawing specified a Rockwell C hardness in a certain range. I expected surface & core hardness done with a Rockwell test (in addition to the HV0.3) but I am confused by the "near-surface" moniker. Can someone help explain?
