铜管显微维氏硬度测定结果的不确定度评定

Uncertainty Evaluation on Microscopic Vickers Hardness Test Results of a Copper Pipe

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。

Abstract: 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%.
