摘　　要：在链条极限拉伸载荷测量中引入了不确定度,通过大量的试验测试找出了影响不确定度的主要因素。在此基础上,推导出计算链条极限拉伸载荷不确定度的公式,给出了不确定度在报告中的表述方法,讨论了不确定度对测量结果的影响。The value of uncertainty in measurement decides reliability of the testing results. Both of the influence factors on uncertainty and calculating method of uncertainty are different for different products and the testing way. Uncertainty was introduced for the first time into the measurement of ultimate strength of chain. A lot of experiments have been conducted and the key influence elements on uncertainty were found out, then the calculating method of uncertainty was educed. At the same time, the expression of uncertainty was presented, and the influence of uncertainty on testing results was discussed.
