Abstract On determining the weighing performance of a non-automatic weighing instrument (NAWI) from a weighing test result, there are 2 kinds of misjudgment risks if simple acceptance rule is applied when the measurement result is close to the maximum permissible error. Taking the test results of 3 electronic balances of a same type as an example, the measurement uncertainty for the corrected indication error is evaluated, whose influences on the conformity assessment is analyzed. The three kinds of conformance probabilities were 95.45%, 80.6% and 18.1%, respectively. The experimental results show that in the measurement process of NAWI, the NAWI whose linear measurement load error meets the maximum permissible error limit may still have the risk of failing to meet the requirements of conformity assessment. In legal metrology, the evaluation of measurement uncertainty of NAWI is an effective method to reduce misjudgment results.
