The use and application of uncertainty analysis in engineering has evolved considerably over the past decade. The methods formulated in the 1970’s and 1980’s that were incorporated into ANSI/ASME Standards and that were used during the AGARD-sponsored Uniform Engine Test Programme (UETP) have been superseded by more rigorous approaches. In this paper, the uncertainty methodogy used in the UETP is compared with the newer approaches that will need to be implemented in future turbine test programs.
