依据GB/T 4340.1-2009对锆合金带材进行了维氏硬度测试，并按照JJF 1059.1-2012对测试结果进行了不确定度评定。结果表明：锆合金维氏硬度测试的不确定度主要来源于压痕对角线长度测量、试验力值测量、标准硬度块不均匀度、硬度计自身不确定度等多个方面；当取包含因子k=2时，扩展不确定度U₉₅=15.82 HV，相对扩展不确定度U_95，rel=7.87%。

According to GB/T 4340.1-2009, the Vickers hardness of zirconium alloy strip was measured, and the uncertainty of the measurement results was evaluated according to JJF 1059.1-2012. The results show that the uncertainty of Vickers hardness measurement of zirconium alloy mainly comes from many aspects such as measurement of indentation diagonal length, test force value measurement, unevenness of standard hardness block and itself uncertainty of hardness tester. When the coverage factor k=2, the extended uncertainty U₉₅=15.82 HV, and the relative extended uncertainty U_95,rel=7.87%.
