以布氏硬度为例,讨论了硬度块示值的均匀度,示值稳定度和基准机不确定度等因素对硬度块示值的影响及硬度块示值总不确定度的计算方法。
Taking Brinell hardness as an example, the influence of hardness value indication uniformity, indication stability and reference machine uncertainty on the indication of hardness block and calculation method of total uncertainty of indication value of hardness block are discussed.
