This International Standard specifies an evaluation procedure that allows the comparis n of two methods with performance characteris ics establis ed in accordance with is /TR 13843 and intended to quantify the same target group or species of microorganis s. It provides the mathematical bases for evaluating the average relative performances of the two quantitative methods in relation to determined comparis n criteria. It does not provide any data enabling the reliability of the methods compared to be assessed. The precis on of methods should be assessed when determining their performance characteris ics.
