摘要
依据GB/T 4340.1—2009对某铜管进行了显微维氏硬度测试,并对显微维氏硬度测定结果的不确定度进行了评定。结果表明:当置信概率取95%时,该铜管的显微维氏硬度的测定结果为(86.5±2.8)HV0.1,k=2。
According to the metallic materials Vickers hardness test standard GB/T 4340. 1--2009, the microscopic Vickers hardness test was done to a copper pipe, and the uncertainty for the microscopic Vickers hardness test results was evaluated. The results show that the microscopic Vickers hardness test results for the copper pipe was （86. 5±2.8） HV0. 1, k=2 under the confidence probability was 95%.
