Abstract During verification process of instrument error,the test results decide UUT qualified or not.Due to the presence of measurement uncertainty,a wrong decision may be made,so consumer and producer decisional risk are caused.To keeping the consumer,s risk(CR) and producer,s risk(PR) below the given target values,a comprehensive control method for setting both the process capability index(PCI),measurement uncertainty ratio(TUR)and gauging tolerance interval ratio(GTR)in conformance testing procedures is proposed.The relation between the three parameters with CR and PR is established.By graphical configuration mode,some effective guidelines for conformance testing design are described.The results of simulation show that PR and CR can be kept below the given target values by suitably setting both the TUR and GTR with a certain PCI.

Key words： Metrology Conformance testing Decisional risk Test uncertainty ratio Gauging tolerance interval ratio
