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.
