# Commission Decision of 12 August 2002 implementing Council Directive 96/23/EC concerning the performance of analytical methods and the interpretation of results (notified under document number C(2002) 3044) (Text with EEA relevance) (2002/657/EC), Division 3.1.1.5: Calibration curves

Extent: E+W+S+N.I.

When calibration curves are used for quantification:
at least five levels (including zero) should be used in the construction of the curve,
the working range of the curve should be described,
the mathematical formula of the curve and the goodness-of-fit of the data to the curve should be described,
acceptability ranges for the parameters of the curve should be described.
When serial calibration based on a standard solution is necessary, acceptable ranges shall be indicated for the parameters of the calibration curve, which may vary from series to series.
