Estimates ofσH—the uniformity of hardness blocks or the variance of hardness values—made from the results of testing Rockwell blocks (60 HRC and 30 HRC) and their equivalent Vickers blocks (700 HV30 and 300 HV10) to determine their reference values are as follows:σH≦ 0.03 HRC for 60 HRC,σH≦ 0.05 HRC for 30 HRC,σH≦1.2 …
