标准简介：This part of ISO 5983 specifies a method for the determination of nitrogen content of animal feeding stuffs according to the Kjeldahl method, and a method for the calculation of the crude protein content.
It concerns a semi-micro rapid routine method using block-digestion, copper catalyst and steam distillation into boric acid.
The method is applicable to the determination of greater than 0,5 % Kjeldahl nitrogen in animal feeding stuffs, pet foods and their raw materials.
The method docs not measure oxidized forms of nitrogen nor heterocyclic nitrogen compounds.
The method docs not distinguish between protein nitrogen and non-protein nitrogen.
NOTE If it is of importance to determine the content of non-protein-nitrogen, an appropriate method can be used.
