PROCEDURE FOR DETERMINING THE UNCERTAINTY IN REPORTED TEST RESULTSNOTE A1.1This procedure is based on the ASHRAE method fordetermining the confidence interval for the average of sever

45、al test results(ASHRAE Guideline 2-1986 (RA90). It should only be applied to testresults that have been obtained within the tolerances prescribed in thismethod (for example, thermocouples calibrated and the appliance operat-ing within 5 % of rated input during the test run).A1.1 For the cooking-ener

46、gy efficiency and productioncapacity results, the uncertainty in the averages of at least threetest runs is reported. For each loading scenario, the uncertaintyof the cooking-energy efficiency and production capacity mustbe no greater than 610 % before any of the parameters for thatloading scenario

47、can be reported.A1.2 The uncertainty in a reported result is a measure of itsprecision. If, for example, the production capacity for theappliance is 30 lb/h (13.6 kg/h), the uncertainty must not begreater than 63 lb/h (61.4 kg/h). Thus, the true productioncapacity is between 27 and 33 lb/h (12.2 and

48、 15 kg/h). Thisinterval is determined at the 95 % confidence level, whichmeans that there is onlya1in20chance that the trueproduction capacity could be outside of this interval.A1.3 Calculating the uncertainty not only guarantees themaximum uncertainty in the reported results, but is also used todet

49、ermine how many test runs are needed to satisfy thisrequirement. The uncertainty is calculated from the standarddeviation of three or more test results and a factor from TableA1.1, which lists the number of test results used to calculate theaverage. The percent uncertainty is the ratio of the uncertaintyto the average expressed as a percent.A1.4 Procedure:NOTE A1.2Section A1.5 shows how to apply this procedure.A1.4.1 Step 1Calculate the average and the standarddeviation for the test result (cooking-energy efficiency orp
