来自十一个国家计量研究所的专家于1980年10月21日至23日在色弗尔国际计量局举行会议。不确定度表述方法工作组讨论了本报告中提到的各项建议,它们是为使对实验数据不确定度的给定能取得一个一致和一般可以接受的方法而提出的。这个新方法放弃了偶然不确定度和系统不确定度的传统分类法,而代之以建议对一些量的直接估计,这些是可以考虑作为一般误差传播定律所需方差和协方差的合理近似。所取得的大多数一致的意见表达在一份建议书中,该建议书共有五条,将提交国际计量委员会批准。
Experts from eleven national metrology institutes met at the International Metrology Institute in Severn from October 21 to 23, 1980. The Working Group on Methods of Expression of Uncertainty discussed the recommendations contained in the present report in order to arrive at a consistent and generally acceptable method of assigning uncertainty to experimental data. This new method gives up the traditional taxonomy of occasional uncertainty and system uncertainty, and instead suggests direct estimates of some quantities, which are reasonable approximations that can be taken into account as the variances and covariances needed for the law of general error propagation. Most of the consensus that has been reached is expressed in a proposal that has five in all and will be submitted to the International Committee on Metrology for approval.
