摘要：

The experimental evaluation of friction coefficient is a common laboratory procedure; however the corresponding measurement uncertainty is not widely discussed. This manuscript examines the experimental uncertainty associated with friction measurements by following the guidelines prescribed in international standards. The uncertainty contributors identified in this analysis include load cell calibration, load cell voltage measurement, and instrument geometric A series of 20 tests, carried out under nominally identical conditions, was performed using a reciprocating pin-on-disk tribometer A comparison between the experimental standard deviation and uncertainty analysis results is provided.
