摘　　要：对GB 28011-2011《鞋类钢勾心》中的硬度和纵向刚度两个强制性检测项目的测试不确定度进行了评估,讨论了硬度和纵向刚度的测量不确定度的产生原因及其评定方法,并对不确定度各个分量进行评定、合成,最后给出了合成不确定度及扩展不确定度。通过不确定度的分析提出了试验中的注意事项。Uncertainty of hardness and longitudinal stiffness which are compulsory test items in GB 28011-2011《shanks for footwear》was evaluated. Sources of uncertainty and the evaluating methods were discussed, and each component of uncertainty was estimated and composed. The combined and expended uncertainties were given. Some notes in test were proposed by analyzing uncertainties.
