Abstract  Through researching the uncertainty evaluation method of natural gas physical properties using in the natural gas flowrate measurement standard,and the uncertainty evaluation method of natural gas component analysis using to calculate those physical properties,derives the uncertainty evaluation method of the natural gas flowrate measurement standard,with GUM method. Using those methods and the testing data of some domestic natural gas flowrate meter calibration station, to evaluate measurement uncertainties of mt primary measurement standard,critical flow venture nozzle secondary measurement standard,turbine meter working measurement standard and their calibrating meters. At the same time, gives the suggestion of the CRMs class using in natural gas component analysis for defferent measurement standard.
