Abstract

A method for determining a failure rate of an electrochemical sensor type for a process, wherein the process is defined by determined values, or value intervals, of a plurality of specified process parameters, and wherein a plurality of defect types is specified for the sensor type, comprising steps as follows: assigning, by means of expert knowledge, a defect rate to each combination of one of the values, or value intervals, of the specified process parameters and one of the specified defect types; and calculating the failure rate of the sensor type according to a calculational specification with application of the defect rates assigned to the combinations of a value, or value interval, of a process parameter and a defect type.
