Hello, I work in a liquid calibration Lab and we are applying for ISO 17025. Basically we verify customers flow meters against our standard and capture the data onto our calibration report. An example is I would perform 4 tests of a specific flow rate and calculate the error in % for each test. Ex: test1 = .12%, test2 = .08%, test3 = .14% and test4 = .09%. How would I determine the uncertainty based on the given data.
