Gives a calibration method and a standard addition method for determining the potassium and sodium contents of animal feeding stuffs by flame-emission spectrometry.

This International Standard specifies a calibration method and a standard addition method for the determination of potassium and sodium contents of animal feeding stuffs by flame-emission spectrometry.

The standard addition method applies if it is not known whether the emissions measured for potassium or sodium are subject to matrix effects. The limit of determination for potassium and sodium is 0,04 g/kg.

The calibration method applies if such matrix effects have been shown to be absent.
