3 PROCEDURE FOR THE ESTIMATION OF UNCERTAINTY IN CREEP TESTS
  3.1 GENERAL PROCEDURE
  3.2 ANALYTICAL PROCEDURE
      Step 1 - Identification of the parameters for which
               uncertainty is to be estimated
      Step 2 - Identification of all sources of uncertainty
               in the test
      Step 3 - Estimation of sensitivity coefficient and
               standard uncertainty for each source of uncertainty
      Step 4 - Calculation of the combined uncertainties of the
               measurands and expanded uncertainty
      Step 5 - Presentation of results
