GB/T50784—2013实施多年以来,有些概念检测人员不是很清楚。本文对于分位值,对于错判概率和漏判概率的理解,以及上下限值系数的来源进行了梳理。举例说明混凝土抗压强度特征值的推定和判断,同时对GB/T50784—2013存在的一些印刷错误进行指正。
GB / T50784-2013 implementation for many years, some of the concept of inspectors is not very clear. In this paper, the disaggregation values, the understanding of the probability of misjudgment and the probability of misjudgment, as well as the sources of the upper and lower limit coefficients are also reviewed. An example is given to illustrate the estimation and judgment of the characteristic value of compressive strength of concrete. At the same time, some printing errors of GB / T50784-2013 are corrected.
