DS DSEN SO 5983-1AC 2009-MAY-20 Anmal feedng stuffs - Determnaton of ntrogen content and calculaton of crude proten content - Part 1 Kjeldahl method
This part of ISO 5983 specifies a method for the determination of the nitrogen content of animal feeding stuffs by the Kjeldahl process, and a method for the calculation of the crude protein content. The method does not measure oxidized forms of nitrogen or heterocyclic nitrogen compounds. This method does not distinguish between protein nitrogen and non-protein nitrogen. If it is important to determine the content of non-protein nitrogen, an appropriate method should be used.
