An uncertainty analysis is applied to resistance test of a ship model, according to Performance Test Code of ASME, in which all possible error sources are listed, evaluated, and summed up with sensitivity coefficients to the final results. The uncertainty analysis for resistance test is divided into two steps. The first step is the analysis on measurement uncertainty itself, and the second is on the process of standardization of the test results. Through these analysis one can easily find main error sources and their routes of the error propagation. In the second step of the uncertainty analysis, i.e., in the analysis of the test results, new error sources come out from the processes of correcting measured data to a standard condition by use of empirical correction formulas, and of fitting data to some functions. These errors should also be analyzed, in accordance with the ordinary error propagation from the measured data to the final results.
