Animal feeding stuffs — Determination of phosphorus content — Spectrometric method

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.
