This part of ISO 8466 describes the Steps to be taken in evaluating the statistical characteristics of the linear calibration function. lt is applicable to methods requiring a calibration. Further Parts of ttis lnternationa~ Standard will cover the determina$. i!! ok IGr%t of detection and FEmit of determination, the effect of Ln$erferences and other performante chara,cteristics lt is intended especially for the evaluation of the pure analytical method and for the calculation of Performance characteristics of the calibration function. In Order to derive comparable analytical results and as a basis for analytical quality control the calibration and evaluation of analytical methods have to be performed uniformly.
