Scope

This International Standard specifies a spectrometric method for the determination of the phosphorus content of
animal feeding stuffs.
The method is applicable to animal feeding stuffs with a phosphorus content less than 50 g/kg. It is particularly
appropriate for the analysis of products with low phosphorus content. For products with higher phosphorus content,
application of a gravimetric method is advised, using for instance quinoline phosphomolybdate.
